Hubble Hangouts

Live Hangouts Each Week!

We have a lot of great hangouts planned, all designed to get everyone engaged in astronomy research and outreach. Comment, present your questions, or just watch. We hope to see you there!

All Hubble Hangout events will also be announced on the Hubble Space Telescope Google Plus page

  1. Mocking the Universe: Better Science Through Data Simulation

    Have you ever wondered how astronomers simulate the large-scale structure of the universe? How do they answer questions like, 'What will #JWST show us?' or 'What can we expect to learn from #WFIRST ?'

    The Space Telescope Science Institute is hosting a mini-workshop this week featuring techniques for simulating the universe where they delve into these questions and many more.

    This workshop will focus on the interface of models and survey design: how can we best inject and extract astrophysical insight into and from data simulations?

    One of the main aims is to identify common ground between various ongoing data simulation efforts associated with diverse facilities on the ground and in space (e.g., ELTs, JWST, LSST, PanSTARRS, WFIRST, ALMA, etc.).

How to Attend a Hangout

All Hubble Hangout events will be announced on the Hubble Space Telescope Google+ page and our YouTube Channel.

  1. The Atmosphere of Exoplanet WASP-33b


    Researchers using NASA's Hubble Space Telescope have detected a stratosphere and temperature inversion in the atmosphere of a planet several times the mass of Jupiter, called WASP-33b.

    Earth's stratosphere sits above the troposphere, the turbulent, active-weather region that reaches from the ground to the altitude where nearly all clouds top out. In the troposphere, the temperature is warmer at the bottom — ground level — and cools down at higher altitudes. The stratosphere is just the opposite: There, the temperature rises at higher altitudes. This is called a temperature inversion, and it happens because ozone in the stratosphere absorbs some of the sun's radiation, preventing it from reaching the surface and warming this layer of the atmosphere. Similar temperature inversions occur in the stratospheres of other planets in our solar system, such as Jupiter and Saturn.

    But WASP-33b is so close to its star that its atmosphere is a scathing 10,000 degrees Fahrenheit, and its atmosphere is so hot the planet might actually have titanium oxide rain.

    Please join Tony Darnell Dr, Carol Christian and Scott Lewis as they discuss the atmosphere of this Jupiter-sized #exoplanet with the astronomers who made the observations.

  2. Hubble Finds Giant Halo Around the Andromeda Galaxy

    he Andromeda galaxy is our Milky Way's nearest neighbor in space. The majestic spiral of over 100 billion stars is comparable in size to our home galaxy. At a distance of 2.5 million light-years, it is so close to us the galaxy can be seen as a cigar-shaped smudge of light high in the autumn sky.

    But if you could see the huge bubble of hot, diffuse plasma surrounding it, it would appear 100 times the angular diameter of the full Moon!

    The gargantuan halo is estimated to contain half the mass of the stars in the Andromeda galaxy itself. It can be thought of as the "atmosphere" of a galaxy. Astronomers using Hubble identified the gas in Andromeda's halo by measuring how it filtered the light of distant bright background objects called quasars. It is akin to seeing the glow of a flashlight shining through a fog.

    This finding promises to tell astronomers more about the evolution and structure of one of the most common types of galaxies in the universe.

    Please join Tony Darnell Dr.Carol Christian and Scott Lewis as they discuss this latest finding from Hubble with the astronomers who made the observations.

  3. Planet Orbiting around Nearby Star Gives Clues to the Formation of Atmospheres

    Astronomers have uncovered new clues about the formation of planets around other stars. One question is, do the atmospheres around planets survive or how are they stripped off? Some of the Earth's atmosphere was stripped off during formation. What happens in other exoplanet systems?

    The question is, why? Please join Tony Darnell Dr.Carol Christian and Scott Lewis as we discuss a peculiar observation made with the Hubble Space Telescope around a nearby exoplanet.

  4. Hubble Observes One-of-a-Kind Star


    Astronomers using NASA's Hubble Space Telescope have uncovered surprising new clues about a hefty, rapidly aging star whose behavior has never been seen before in our Milky Way galaxy. In fact, the star is so weird that astronomers have nicknamed it "Nasty 1," a play on its catalog name of NaSt1. The star may represent a brief transitory stage in the evolution of extremely massive stars.

    First discovered several decades ago, Nasty 1 was identified as a Wolf-Rayet star, a rapidly evolving star that is much more massive than our sun. The star loses its hydrogen-filled outer layers quickly, exposing its super-hot and extremely bright helium-burning core.

  5. Hubble Observations Reveal New Insights into the Behavior of Pluto’s Moons

    Surprising new results from Hubble Space Telescope observations show new, hitherto unknown behavior of Pluto’s moons. Astronomers have been monitoring and imaging the Pluto system at various times throughout Hubble’s mission. Many of these observations were used to support science planning for NASA’s New Horizons’ observations.

    Please join us for this week's #HubbleHangout to learn about these exciting Hubble findings in anticipation of the New Horizons spacecraft flyby of Pluto in July 2015!

  6. Shock Collision Inside Black Hole Jet

    Observations over the past 20 years reveal high-energy collisions inside the black hole jet in NGC 3862! While it has been known that the jets from black holes are extremely energetic, shooting out particles at about 98% the speed of light, astronomers were quite "shocked" to see that there were collisions inside the jets themselves!

    This week, join Tony Darnell, Dr. Carol Christian and Scott Lewis as they host the HubbleHangout , discussing the science behind this discovery with the astronomers that used the Hubble Space Telescope to make the observations and publish their findings!

  7. White Dwarf Migration in Ancient Star Clusters

    Using NASA's Hubble Space Telescope astronomers have captured for the first time snapshots of fledgling white dwarf stars beginning their slow-paced, 40-million-year migration from the crowded center of an ancient star cluster to the less populated suburbs.

    White dwarfs are the burned-out relics of stars that rapidly lose mass, cool down, and shut off their nuclear furnaces. As these glowing carcasses age and shed weight, their orbits begin to expand outward from the star cluster's packed downtown. This migration is caused by a gravitational tussle among stars inside the cluster. Globular star clusters sort out stars according to their mass, governed by a gravitational billiard-ball game where lower mass stars rob momentum from more massive stars. The result is that heavier stars slow down and sink to the cluster’s core, while lighter stars pick up speed and move across the cluster to the edge. This process is known as "mass segregation." Until these Hubble observations, astronomers had never definitively seen the dynamical conveyor belt in action.

    Astronomers used Hubble to watch the white-dwarf exodus in the globular star cluster 47 Tucanae, a dense swarm of hundreds of thousands of stars in our Milky Way galaxy. The cluster resides 16,700 light-years away in the southern constellation Tucana.

  8. New Galaxy Distance Record Made with HST


    With images like the eXtreme Deep Field, we’ve seen how the +Hubble Space Telescope is used to observe remarkable distances in our Universe, approaching moments after the Universe ceased to be opaque. Astronomers have done it again, detecting and measuring the distance to some of the earliest objects in our Universe!

    Since light has a finite speed limit, we know that the further back we look, we are also looking further back in time as well. In a joint effort between HST, The Spitzer Space Telescope and the W. M. Keck Observatory in Mauna Kea, Hawai’i, astronomers have observed light from a galaxy that left over 13 billion years ago! Due to the fact that the Universe is expanding at an accelerated rate, researchers measure the “red-shifting” of light of distant objects in order to see how much the light has stretched as space-time itself is stretched. However the further back we go, the fainter the objects are and make this form of spectroscopy extremely difficult to utilize.

    So how did astronomers measure this distant object? Find out in this week’s HubbleHangout! Join your hosts Tony Darnell, Dr.Carol Christian and Scott Lewis as they discuss the findings published in Science with authors Dr. Pascal Oesch and Dr. Garth Illingworth.

  9. Hubble's 25th Anniversary Celebration

    Twenty five years ago today, the +Hubble Space Telescope was launched aboard the Space Shuttle Discovery to usher in a new era of observing the Universe.

    For this special Friday HubbleHangout , your trusty co-hosts +Tony Darnell, Dr.Carol Christian and Scott Lewis will be discussing their favorite images, discoveries and accomplishments that have been made over the past quarter century with our grand telescope.

    Also joining the team is European Space Agency, ESA's Georgia Bladon who will be presenting the winners of the OdeToHubble competition! Many fantastic entries were submitted and you can view the "Shortlist" here: http://www.spacetelescope.org/projects/Hubble25/odetohubble/

    We're also looking to hear from you about YOUR favorite memories, images and breakthroughs from Hubble. Please search through our image gallery and News Center, and let us know in comments below or tweet at us with the hashtag #HubbleHangout

  10. Hubble: The Man Behind the Name


    As we approach the 25th anniversary of the Hubble Space Telescope launching into space, we will be taking time to recognize the man who the famous telescope is named after: Edwin Hubble.

    Edwin Hubble is most widely known for being the astronomer that observed and detected the cepheid variable inside M31 The Great Nebula in Andromeda (now known as the Andromeda Galaxy), which was the evidence needed to show that the Universe we reside in is not a static one, but was expanding.

    These observations were made at the Mount Wilson Observatory in the 1920s and heralded a new way for humanity to understand the Universe.

    Please join Tony Darnell, Dr. Carol Christian and Scott Lewis, who will be on location at the Carnegie Observatories office in Pasadena Calfornia, with Dr. John Mulchaey the acting director of the Carnegie Observatories as well as Nicholas (Nik) Arkimovich, a senior docent at the Mount Wilson Observatory. Together, they will bring fascinating insights into who Edwin Hubble was, as well as his remarkable achievements in astronomy.

  11. Stellar Evolution in Milky Way Type Galaxies

    Star formation and evolution in galaxies like our Milky Way have distinct characteristics that are only now being surveyed and understood. With help from the Hubble Space Telescope, astronomers are beginning to get more information to help them fill in pieces of the puzzle.

    Please join Tony Darnell Dr.Carol Christian and Scott Lewis as they discuss some of the latest results of a survey recently completed by Hubble that sheds more light on what we know about stellar evolution in galaxies like ours.

  12. Quasars and Active Galactic Nuclei

    Most galaxies have at their cores a supermassive black hole hundreds of millions of times the mass of our Sun. They emit powerful ultraviolet radiation from the supermassive black hole at the core of the host galaxy.

    The most active of these galaxy cores are called quasars, where infalling material is heated to a point where a brilliant searchlight shines into deep space. The beam is produce by a disk of glowing, superheated gas encircling the black hole.

    Please join Tony Darnell Dr. Carol Christian and Scott Lewis as they discuss some fascinating new observations of quasars made by the Hubble Space Telescope

  13. Astronomers Find Dark Matter Even Darker than Previouosly Thought


    Astronomers using observations from NASA’s Hubble Space Telescope and Chandra X-ray Observatory have found that dark matter interacts with itself even less than previously thought by researchers. This finding narrows down the options for what this mysterious substance might be, say researchers.

    By finding that dark matter interacts with itself even less than previously thought, the team has successfully narrowed down the properties of dark matter. Particle physics theorists have to keep looking, but they now have a smaller set of unknowns to work with when building their models.

    Please join Tony Darnell, Dr.Carol Christian and Scott Lewis as they discuss these amazing observations with the team that made them.

  14. The Hubble Source Catalog: Find Everything Hubble Has Ever Seen

    Astronomers at the Space Telescope Science Institute and the Johns Hopkins University, both in Baltimore, Md., have created a new master catalog of astronomical objects called the Hubble Source Catalog. The catalog provides one-stop shopping for measurements of objects observed with NASA’s Hubble Space 
Telescope.

    Hubble has amassed a rich legacy of images and other scientific data over its 25 years of exploring the universe. All of the images are stored in the computer-based Barbara A. Mikulski Archive for Space Telescopes (MAST), which astronomers use for their research. The archive is bursting with more than a million images, which contain roughly 100 million small sources ranging from distant galaxies to compact star clusters to individual stars. For astronomers, however, a major challenge is the difficulty involved with sifting through the archival gold mine to collect the data they want to analyze. The Hubble Source Catalog now allows astronomers to readily perform a computer search for characteristics of these sources.

    The Hubble Source Catalog is a database from which astronomers can obtain the Hubble measurements of specific astronomical objects they want to investigate. A query to this database can take just seconds or minutes, while previously it might have required a few months of hard work by searching separate files throughout the archive. This capability promises to open the door to exciting new areas of research with Hubble that otherwise might have been too cumbersome to tackle.

  15. Hubble Observations Suggest Subsurface Ocean on Jupiter's Largest Moon Ganymede

    Nearly 500 million miles from the Sun lies a moon orbiting Jupiter that is slightly larger than the planet Mercury and may contain more water than all of Earth’s oceans. Temperatures are so cold, though, that water on the surface freezes as hard as rock and the ocean lies roughly 100 miles below the crust. Nevertheless where there is water there could be life as we know it.

    Identifying liquid water on other worlds – big or small – is crucial in the search for habitable planets beyond Earth. Though the presence of an ocean on Ganymede has been long-predicted based on theoretical models, NASA’s Hubble Space Telescope found the best circumstantial evidence for it. Hubble was used to watch aurorae glowing above the moon’s icy surface. The aurorae are tied the moon’s magnetic field which descends right down to the core of Ganymede. A saline ocean would influence the dynamics of the magnetic field as it interacts with Jupiter’s own immense magnetic field that engulfs Ganymede.

    Because telescopes can’t look inside planets or moons, tracing the magnetic field through aurorae is a unique way to probe the interior of another world.

    Please join Tony Darnell Dr. Carol Christian and Scott Lewis as they discuss these observations with the science team.

  16. Hubble Sees Supernovae Split into Four Images by Gravitational Lens


    Astronomers using NASA’s Hubble Space Telescope have spotted for the first time a distant supernova split into four images. The multiple images of the exploding star are caused by the powerful gravity of a foreground elliptical galaxy embedded in a massive cluster of galaxies.
    This unique observation will help astronomers refine their estimates of the amount and distribution of dark matter in the lensing galaxy and cluster. Dark matter cannot be seen directly but is believed to make up most of the universe’s mass.

    These observations were taken as part of the Frontier Fields Survey.

    Please join Tony Darnell Dr.Carol Christian and Scott Lewis as they discuss these exciting observations with members of the Frontier Fields Team.

  17. Hypergiants, Hypernovae and Hubble

    Hypergiant stars are among the largest and most luminous in the universe and when they die, they create an enormous explosion, known as hypernovae. Astronomers using the Hubble Space Telescope have observed several supernovae in galaxies NGC 266 and NGC 7714 and believe them to be caused by the deaths of these hypergiant stars.

    Please join Tony Darnell Dr. Carol Christian and Scott Lewis as they explore the realm of hypergiant stars and discuss recent Hubble observations of SN 2005gl and others.

  18. Hubble and the Debris Disk of Beta Pictoris


    Beta Pictoris remains the only directly imaged debris disk that has a giant planet (discovered in 2009) with an orbital period short enough (estimated to be between 18 and 22 years) that astronomers can see large motion in just a few years. This allows scientists to study how the Beta Pictoris disk is distorted by the presence of a massive planet embedded within the disk.

    Please join Tony Darnell, Dr. Carol Christian and Scott Lewis as they discuss new visible-light Hubble images that traces the disk in closer to the star to within about 650 million miles of the star with the astronomers who made them.

  19. 25 Images Celebrating 25 Years of Hubble


    This year marks 25 years of amazing images and science from the Hubble Space Telescope. To celebrate, we've assemble 25 images that represent both the beauty of the universe captured by Hubble and the important science realized by this wonderful telescope orbiting over our heads.

    Please join Tony Darnell, Dr Carol Christian and Scott Lewis as they discuss these images with Dr. Ken Sembach, Hubble Mission Head at STScI.

  20. Hubble Observes Rare Jupiter Conjunction

    Europa, Callisto, and Io, three of Jupiter’s four largest moons, can commonly be seen transiting the face of the giant planet and casting shadows onto its cloud tops. However, seeing three moons transiting the face of Jupiter at the same time is rare, occurring only once or twice a decade.

    On Janurary 24th, 2015, the Hubble Space Telescope captured a rare look at three of Jupiter’s largest moons zipping across the banded face of the gas giant planet.

    Please join Tony Darnell, Dr Carol Christian and Scott Lewis as they discuss the observations with Zolt Levay and Mike Wong.

  21. More Hubble History


    Given the long, storied history of the Hubble Space Telescope including 25 years of discoveries, we are holding a series of Hubble Hangouts dedicated to exploring its history. This is the second hangout in that series.

    Please join Tony Darnell, Dr Carol Christian and Scott Lewis as they discuss some of the early discoveries of Hubble with the author of several books on Hubble, Carolyn Collins Petersen and ESA Mission Head for Hubble, Dr. Antonella Nota.

  22. Hubble Discovers Powerful Winds in Milky Way Core


    At a time when our earliest human ancestors had recently mastered walking upright, the heart of our Milky Way galaxy underwent a titanic eruption, driving gases and other material outward at 2 million miles per hour. Now, at least 2 million years later, astronomers are witnessing the aftermath of the explosion: billowing clouds of gas towering about 30,000 light-years above and below the plane of our galaxy.

    The enormous structure, dubbed the Fermi Bubbles, was discovered five years ago as a gamma-ray glow on the sky in the direction of the galactic center. The balloon-like features have since been observed in X-rays and radio waves. But astronomers needed NASA's Hubble Space Telescope to measure for the first time the velocity and composition of the mystery lobes. They now seek to calculate the mass of the material being blown out of our galaxy, which could lead them to determine the outburst's cause from several competing scenarios. The graphic shows how Hubble probed the light from a distant quasar to analyze the outflow. The quasar's light passed through one of the bubbles. Imprinted on that light is information about the outflow's speed, composition, and eventually mass.

  23. The First Stars and Galaxies


    The first stars and galaxies formed in the early universe had very distinctive properties we've only just begun to understand. With the help of Frontier Fields, we've looked back into time as far as Hubble will allow and we've learned some remarkable things about these early times.

    We await the launch of JWST to learn more, and this hangout will feature Massimo Stiavelli, an astronomer who specializes in the early universe and manager of the JWST Mission at STScI.

    Please join Tony Darnell and Dr Carol Christian as they look towards the exciting science the James Webb Space Telescope will provide to help us understand the first stars and galaxies in the early universe.

  33. Hubble and Dawn Collaborate to Observe Ceres

    As the Dawn Spacecraft approaches the dwarf planet Ceres in a matter of months, it's difficult to forget the amount of teamwork and collaboration that took place in order for amazing feats like this to be accomplished.

    As of right now, the +Hubble Space Telescope has the highest resolution image of Ceres, but that's all about to change as Dawn arrives and gives us all a completely new perspective of the largest object in the asteroid belt. In fact, the images taken by Hubble have been highly instrumental in the planning phases of getting Dawn to Ceres, as well as Vesta.

    To continue in the spirit of collaboration, this week's #HubbleHangout will be with those involved in imaging Ceres with Hubble as well as members of the +Dawn Mission Education and Communications (E/C) team!

    Please join Tony Darnell Dr Carol Christian and Scott Lewis, who will be on location at NASA Jet Propulsion Laboratory with +Keri Bean as we discuss the long journey Dawn has made to get to Ceres. Joining them as well is Max Mutchler and Jianyang Li who worked on getting the gorgeous view from Hubble.

    Bring your questions and comments and we'll read them on air throughout the hangout!

  34. Hubble Surveys Debris Disks Around Stars


    Astronomers using NASA's Hubble Space Telescope have completed the largest and most sensitive visible-light imaging survey of dusty debris disks around other stars. These dusty disks, likely created by collisions between leftover objects from planet formation, were imaged around stars as young as 10 million years old and as mature as more than 1 billion years old.

    Once thought to be simply pancake-like structures, the unexpected diversity and complexity of these dusty debris structures strongly suggest they are being gravitationally affected by unseen planets orbiting the star. Alternatively, these effects could result from the stars' passing through interstellar space.

    Please join Tony Darnell Dr Carol Christian and Scott Lewis as we talk with the Principal Investigators of this exciting discovery.

    Bring your questions and comments and we'll read them on air throughout the hangout!

  35. Hubble Finds Extremely Distant Galaxy in Gravitational Lens

    Peering through a giant cosmic magnifying glass, NASA's Hubble Space Telescope has spotted one of the farthest, faintest, and smallest galaxies ever seen. The diminutive object is estimated to be over 13 billion light-years away.
    This new detection is considered one of the most reliable distance measurements of a galaxy that existed in the early universe, said the Hubble researchers. They used two independent methods to estimate its distance.

    The galaxy was detected as part of the Frontier Fields program, an ambitious three-year effort, begun in 2013, that teams Hubble with NASA's other Great Observatories — the Spitzer Space Telescope and the Chandra X-ray Observatory — to probe the early universe by studying large galaxy clusters. These clusters are so massive that their gravity deflects light passing through them, magnifying, brightening, and distorting background objects in a phenomenon called gravitational lensing. These powerful lenses allow astronomers to find many dim, distant structures that otherwise might be too faint to see.

    Please join Tony Darnell, Dr Carol Christian and Scott Lewis as we talk with the Principal Investigators of this exciting discovery.

  36. How to Operate the Hubble Space Telescope


    Have you ever wondered how +NASA and the Space Telescope Science Institute actually drive Hubble? How do we point it? How do we get the data down from orbit? How do we communicate with it? How do we know when something goes wrong and what do we do about it?

    Please join Tony Darnell, Dr Carol Christian and Scott Lewis as we talk with the engineers/scientists from +NASA Goddard who operate our beloved Hubble Space Telescope.

    Bring your questions and comments and we'll read them on air throughout the hangout!

  37. The Thermal Map of Exoplanet WASP 43b

    Located 260 light-years away, exoplanet WASP-43b is no place to call home. It is a world of extremes, where seething winds howl at the speed of sound from a 3,000-degree-Fahrenheit day side, hot enough to melt steel, to a pitch-black night side with plunging temperatures below 1,000 degrees Fahrenheit. The Hubble Space Telescope has been used to make the most detailed global map yet of the thermal glow from this turbulent world. The astronomers were also able to map temperatures at different layers of the world's atmosphere and traced the amount and distribution of water vapor. The Jupiter-sized planet lies so close to its orange dwarf host star that it completes an orbit in just 19 hours. The planet is also gravitationally locked so that it keeps one hemisphere facing the star.

    Please join Tony Darnell, Dr Carol Christian and Scott Lewis as we talk with the principal investigators of this interesting science.

    Hope you can all make it, please bring your questions and comments!

  41. The Exciting Possibilities of 3D Printing in Zero-G


    NASA is currently engaged in exploring of 3D printing in space using a printer designed by Made In Space. This printer is designed to work in a microgravity environment to produce space assets in... well... SPACE!

    NASA wants to test the idea of making parts inexpensively in orbit as opposed to down here on Earth and launching them to where they need to be.

    3D printing serves as a fast and inexpensive way to manufacture parts on-site and on-demand, reducing the need for costly spares on the International Space Station and future spacecraft. Long-term missions would benefit greatly from having onboard manufacturing capabilities. Data and experience gathered in this demonstration will improve future 3-dimensional manufacturing technology and equipment for the space program, allowing a greater degree of autonomy and flexibility for astronauts.

    Please join Tony Darnell Dr Carol Christian and Scott Lewis as they discuss this new experiment from NASA with Jason Dunn and Michael Snyder from Made in Space, the company contracted by NASA to build the 3D printer currently being used.

  42. The Scientific and Cultural Impact of Hubble; Meet ATLAST, a Next Generation Space Telescope

    In the 24 years Hubble has been exploring the universe, we have gone through four U.S. Presidents, and 5 U.K. Prime Ministers. For many astronomers, this time represents almost half a career and for people under 25, they have never known a world without the Hubble Space Telescope in it.

    This exciting hangout will take a look at all of the things the Hubble Space Telescope has done for us, both scientifically and culturally with Dr. Martin Barstow, Pro-Vice-Chancellor, Head of the College of Science & Engineering, Professor of Astrophysics & Space Science and President of the Royal Astronomical Society.

    Later in the hour, he will also introduce us to ATLAST, The Advanced Technology Large Aperture Space Telescope. ATLAST is a NASA strategic mission concept study for the next generation of UVOIR space observatory. ATLAST will have a primary mirror diameter in the 8m to 16m range that will allow us to perform some of the most challenging observations to answer some of our most compelling astrophysical questions. We have identified two different telescope architectures, but with similar optical designs, that span the range in viable technologies. The architectures are a telescope with a monolithic primary mirror and two variations of a telescope with a large segmented primary mirror. The concepts invoke heritage from HST and JWST design, but also take significant departures from these designs to minimize complexity, mass, or both. ATLAST will have an angular resolution that is 5 - 10 times better than the James Webb Space Telescope (JWST) and a sensitivity limit that is up to 2000 times better than the Hubble Space Telescope (HST).

    Please join Tony Darnell Dr Carol Christian and Scott Lewis as they discuss the impact of Hubble and this exciting new NASA mission.

  43. James Webb Space Telescope Update: Sunshield Deployment Test


    In August 2014, at their Northrop Grumman facilities in Redondo Beach, California engineers successfully stacked and unfurled the five layers of the largest part of the observatory: the massive sunshield.

    The successful unfurling was the first time this had been done and everything worked perfectly.

    The Sunshield is about the length of a tennis court, and will be folded up like an umbrella around the Webb telescope’s mirrors and instruments during launch. Once it reaches its orbit, the Webb telescope will receive a command from Earth to unfold, and separate the Sunshield's five layers into their precisely stacked arrangement with its kite-like shape.

    Please join Tony Darnell, Dr Alberto Conti and Scott Lewis as they discuss the test conducted last Summer with engineers and scientists at Northrup Grumman and NASA Goddard as well as the details of the deployment of the James Webb Space Telescope.

    As always, we look forward to your questions and comments as well, see you then!

  44. 3D Astronomy: Modelling the Universe with 3d Printers


    3D printing technology offers huge benefits in astronomy education and research. The 3D Astronomy Project at the Space Telescope Science Institute and NASA Goddard have created innovative education materials and 3D models of astronomical objects using #Hubble data.

    Please join Tony Darnell. Dr Carol Christian and Scott Lewis as they discuss how 3D printing is being used in both education and research as well as helping the visually impaired.

    As always, we look forward to your questions and comments as well, see you then!

  45. Hubble Finds Evidence of Water Vapor Plumes on Europa


    NASA's Hubble Space Telescope has observed water vapor above the frigid south polar region of Jupiter's moon Europa, providing the first strong evidence of water plumes erupting off the moon's surface.

    Previous scientific findings from other sources already point to the existence of an ocean located under Europa's icy crust. Researchers are not yet certain whether the detected water vapor is generated by water plumes erupting on the surface, but they are confident this is the most likely explanation.

    Please join Tony Darnell, Dr Carol Christian and Scott Lewis as they discuss the latest findings from the astronomers making the #Hubble observations of this exciting discovery!

    As always, we look forward to your questions and comments as well, see you then!

  46. All Things Supernovae!

    Note! Special Day! Wednesday September 10th!

    Supernovae are among the most spectacular events in the universe. They happen when massive stars reach the end of their lives and explode with a luminosity that can outshine an entire galaxy and will emit more energy than the Sun does in its entire lifetime.

    While there is much we do know about these events, astronomers still have lots of questions and research is constantly uncovering more of the mysteries surrounding the deaths of massive stars.

    Please join Tony Darnell Dr Carol Christian and Scott Lewis as they discuss the latest findings in the study of supernovae from #Hubble and other research efforts.

    As always, we look forward to your questions and comments as well, see you then!

  47. Calibrating Hubble Data: Decoding the Secrets of the Distant Universe

    Have you ever wondered how astronomers are able to tease out the secrets of the distant universe from faint smudges of light in a Hubble image? How are they able to know what chemical elements are in an exoplanet atmosphere? How can they tell the difference between a galaxy, star or a cosmic ray on the detector?

    Please join Tony Darnell Dr. Carol Christian and Scott Lewis as they discuss the calibration of data from the Hubble Space Telescope with astronomers attending a special Hubble Data Calibration Workshop. Learn the secrets of getting science from Hubble images! 

  48. Hubble Finds Three Surprisingly Dry Exoplanets

    Astronomers using NASA's Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the Sun — and have come up nearly dry.

    The three planets, HD 189733b, HD 209458b, and WASP-12b, are between 60 and 900 light-years away. These giant gaseous worlds are so hot, with temperatures between 1,500 and 4,000 degrees Fahrenheit, that they are ideal candidates for detecting water vapor in their atmospheres.

    However, to the surprise of the researchers, the planets surveyed have only one-tenth to one one-thousandth the amount of water predicted by standard planet-formation theories.

  49. Hubble Observes Strange Structure in a Galaxy Collision

    Recent observations from the Hubble Space Telescope have uncovered an uncanny 100,000-light-year-long structure that looks like a string of pearls twisted into a corkscrew shape that winds around the cores of two colliding galaxies. The unusual structure may yield new insights into the formation of stellar superclusters, the merger-driven growth of galaxies, and gas dynamics in the rarely seen merger process of two giant elliptical galaxies.

    Please join Tony Darnell, Dr. Carol Christian and Scott Lewis as they discuss this discovery with the astronomers who made the observations and working to understand the origin of this chain of young, blue "super star clusters".

    As always, your comments and questions are encouraged and welcome!

  50. How Can We Directly Image Exoplanets?

    What telescopes are needed to see exoplanets directly? Can we do it with the #Hubble Space Telescope? What would we see if we could design a telescope specifically for imaging planets around other stars?

    Are there any telescopes in the planning stages? The answer is yes. Astronomers are currently planning and building several telescopes that will directly resolve telescopes including #JWST and the Advanced Technology Large-Aperture Space Telescope (ATLAST).

    Please join Tony Darnell Dr. Carol Christian and Scott Lewis as they discuss the technical challenges of imaging exoplanets directly with Dr. Mark Clampin of #NASA and the telescopes that are being designed and built to perform these very difficult observations.

    As always, we welcome your comments and questions!

  51. How to Use the Hubble Space Telescope

    Have you ever wondered how astronomers decide what the Hubble Space Telescope observes? Who gets access to the most powerful telescope in orbit above the Earth? How do we determine what objects Hubble focuses on?

    Follow us on a journey as an observing proposal for the Hubble Space Telescope goes from idea to observations to data to analysis. Please join Tony Darnell, Carol Christian and Scott Lewis as they discuss how the Hubble Space Telescope is used with the astronomers who are charged with its operation.

    We hope you'll comment and ask questions as well!

  52. Planetary Aurorae in Our Solar System

    Did you know that Earth is not the only planet in our solar system to have magnificent displays of aurorae?

    For over two decades, the Hubble Space Telescope has observed planets and aurorae within the confines of our solar system . Please join us as Tony Darnell, Carol Christian and Scott Lewis explore the aurorae of other planets with astronomers who have made these observations.

    As always, please interact with us by commenting and leaving questions, we'd love to hear from you!

  53. Hubble, White Dwarfs, Cataclysmic Variables and Amateur Astronomers


    Amateur astronomers have played a big role in astronomical research and the Hubble Space Telescope is not alone in enjoying the fruits of their labors.

    When astronomers asked the question, Can white dwarfs in binary systems grow in mass? Amateurs were on hand to help guide Hubble to the best observations.

    Understanding whether white dwarfs can gain mass is important, especially since they are the sources of a very important cosmic yardstick: Type 1a supernovae. These supernovae were directly responsible for showing us that the universe is expanding and accelerating - which meant that it also gave rise to the idea of dark energy.

    But making these observations of white dwarfs in order to see if they were gaining mass was tricky and older, rejected theories that cataclysmic variables might be the progenitors of Type 1a supernovae were being revisited.

    Please join Tony Darnell, Carol Christian and Scott Lewis as they discuss this very interesting Pro/Amateur collaboration using the Hubble Space Telescope to better understand Type 1a supernovae, white dwarf stars and cataclysmic variables.

    Please bring your questions and comments and we'll address them during the hangout as well!

  54. The Science of the Pan-STARRS Survey

    High atop Haleakala on the island of Maui sits a telescope with a three-degree field of view and the largest digital camera ever built, recording 1.4 BILLION pixels with every image. In operation since June 2006 and concluded observation in March 2014, the data are now housed in The Mukulski Archive for Space Telescopes (MAST) at the Space Telescope Science Center.

    Please join Tony Darnell, Dr. Carol Christian and Scott Lewis as we discuss what science is possible using a large digital camera staring at very large portions of the sky with members of the Pan-STARRS team.

  55. The Continuing Evolution of the Hubble Ultra Deep Field

    One of the most amazing pictures ever returned from the Hubble Space Telescope, the Ultra Deep Field (HUDF), has just been enhanced. Astronomers using the WFC3/UVIS camera on Hubble have included ultraviolet wavelengths to the image, which already had optical and infrared compnents. We now have the most comprehensive wavelength range of any deep field image ever taken. Please join Tony Darnell, Dr. Carol Christian and Scott Lewis as they discuss how Hubble added this new data and how it impacts our understanding of the universe with the science team that took it.

  56. The "Teenage Years" of Quasars

    Quasars are among the brightest outflows of energy in the universe with an intrinsic brightness of one trillion suns. Most quasars appear as pinpoint sources in the biggest telescopes we have. Astronomers believe quasars are produced by energy coming from over-fed supermassive black holes, with most of them erupting 12 billion years ago.

    The question is, why? Please join Tony Darnell Dr.Carol Christian and Scott Lewis us as we discuss these fascinating objects with astronomers studying them using the Hubble Space Telescope. Learn about the latest research and explore the current thinking of what caused quasars and what was happening in the early universe 12 billion years ago.

  57. Frontier Fields: Survey Progress Update!

    It's been about six months since we've last checked in with the #FrontierFields team back at the January AAS and we thought it was time to get together to see how things were progressing.

    Frontier Fields is one of the most ambitious #Hubble observing programs ever launched. It will stare at six different clusters in varying places in the sky for over 560 orbits in an attempt to answer, among other things: Are what we see in the Hubble Ultra Deep Field images typical? Are the 10,000 galaxies seen in that small patch of sky unique or are they everywhere?

    The Frontier Fields team is eight months into its three year program and we will be holding regular hangouts throughout to touch base with the effort and learn what, if any, new discoveries are coming out of the Frontier Fields images.

    Please join +Tony Darnell , +Carol Christian and +Scott Lewis as they discuss the latest developments and discoveries from the Frontier Fields science team.

  58. The Incredible Shrinking Great Red Spot


    Using +Hubble Space Telescope observations from the past and including recent observations this year, astronomers have measured the diameter of Jupiter's Great Red Spot at approximately 10,250 miles across, the smallest ever measured.

    Astronomers have known that the giant storm feature on Jupiter has been shrinking since the 1930s, and now we have several decades of observations that show just how much and at what rate.

    By comparison, the Great Red Spot was 14,500 miles across when NASA's Voyager 1 and Voyager 2 spacecraft flew by Jupiter in 1979.

    Starting in 2012, amateur observations revealed a noticeable increase in the spot’s shrinkage rate. The GRS’s “waistline” is getting smaller by 580 miles per year. The shape of the GRS has changed from an oval to a circle. The cause behind the shrinking has yet to be explained.

    These new observations also show that very small eddies are feeding into the storm and my be responsible for the sudden change by altering the dynamics and energy of the Great Red Spot.

    Please join +Tony Darnell and +Carol Christian as they discuss these new observations with Dr. Amy Simon and others and bring your questions and comments. We look forward to seeing you there!

  59. Habitable Worlds: What Conditions for Life are Really Important?


    There is a fascinating workshop being held this week in Baltimore at the Space Telescope Science Institute: Habitable Worlds: Across Time and Space.

    The symposium is designed to provide discussion of topics related to the challenges life faces both beginning and developing on a planetary body -- either within our solar system or on distant #Exoplanets

    +Tony Darnell, +Carol Christian , physicist Eva Villaver, and +Mario Livio will hold a hangout this week to discuss, among a great many other interesting topics:

    •How well does the specific challenges facing habitability on Earth extend to other planets in our solar system and exoplanets?
    •What role does the galactic habitable zone play? How important is it?
    •What are the limits to Earth-like life?
    •Habitability of planets and moons during all phases of stellar evolution
    •Habitability in low-luminosity environments

    We hope you can make it live. But if you can't, remember that it will be archived on our YouTube Channel. Please bring any questions and comments and we'll try to answer them.

    See you there!

  60. New Technique Increases Hubble's Precision by a Factor of 10

    Astronomers at the Space Telescope Science Institute have devised a new technique that allows the +Hubble Space Telescope to more accurately measure distances to stars within our galaxy - up to 10 times farther than previously possible using a method known as parallax.

    Parallax is the most reliable method for directly measuring distances to stars within our galaxy. It uses the geometry of the Earth's orbit around the Sun to see tiny, almost imperceptible shifts of background stars behind the object being measured.

    Previously this technique was only effective for distances up to 750 light years. Anything further away and we couldn't see the background stars shift; the change was too small.

    This new capability allows astronomers using the Hubble Space Telescope to measure parallax distances up to 7,500 light years away - an astonishing increase in precision of a factor of 10!

    Please join us as +Tony Darnell and +Scott Lewis discuss this new technique with Dr. Adam Riess, winner of the 2011 Nobel Prize in Physics and Dr. Stefano Casertano, the developers of this new ability for #Hubble.

  61. The Citizen Scientists of Stardate: M83

    Early this year, along with +The Zooniverse folks, we ran a citizen scientist campaign designed to help astronomers get age dating information for star clusters in the galaxy M83 (also known as the Southern Pinwheel Galaxy).

    The project was a resounding success, providing astronomers with a plethora of information to help understand the ages of star clusters and their gas content. Now, we'd like to take time to discuss what some of the more prolific amateur astronomers experienced and to get their insights and advice for doing this kind of science online.

    Please join +Tony Darnell, +Carol Christian and others as we discuss the project with the citizen scientists who used it the most.

  62. The Cosmic Distance Scale


    How do we know how far away things are in the universe? What Yardsticks to we use and how accurate are they?

    On Monday, March 31, a workshop will be held at The Space Telescope Science Institute to discuss these topics and more. As an added bonus, Dr. Adam Riess, winner of the 2011 Nobel Prize in Physics will join +Tony Darnell and Mario Livio to share his unique insights into this important topic in a hangout Monday Evening.

    Dr. Riess won his Nobel Prize using one of the best yardsticks in the universe to measure distance: Type 1a supernova. We hope you can join us and bring your questions!

    You can watch the talks from the workshop here:

  63. Hubble and James Webb Space Telescope Go to SXSW


    We're going to SXSW again this year! This event will one of our social media focal points where you can participate either vicariously through the people who are at the event or you can stop by and say hi if you are in Austin.

    We invite people to post their #JWST or #Hubble and #SXSW related photos. We'll also be live streaming a few events while we're there so you can comment and interact on these pages during that as well.

    We are really looking forward to SXSW this year - we will have a booth at the Gaming Expo which will be held from March 7th through the 9th. Stay tuned for scheduled events to be posted here as the big event arrives.

  64. What Are NASA's Astrophysics Priorities?


    Every 10 years, astronomers get together to decide what questions they would MOST like answered.

    The results are compiled in a document known as the Decadal Survey. This survey is usually the starting point for deciding what missions NASA would like to get involved in and fund.

    For example in the 2000 Decadal Survey, The James Webb Space Telescope was the top priority to the science community. In the more recent 2010 Survey, WFIRST was top of the list.

    But these surveys describe the science opportunities that face us now and help greatly in prioritizing near-term programs for the next decade.

    But what about the next 30 years?

    NASA wants takes a long-range view that highlights the science possibilities over the next 30 years and provides the inspiration and rationale for continuing American leadership and investment in NASA's astrophysics programs.

    They call it the NASA Astrophysics Roadmap and they have just completed it.

    If you are interested in the long-term astrophysics mission of NASA over the next 30 years, please join +Tony Darnell and +Jason Kalirai as they discuss these plans with the Chair of the Road Map Committee along with many of it's members.

    This hangout will provide you with unprecedented access to many people who help shape NASA's science future, and it promises to be very exciting.

    We hope you can make it! If not, as always, it will be archived on our YouTube Channel for later viewing.

    We will have the Q&A app running during the event so you can communicate with us and we'll also be looking at your comments on Twitter ( #Hubblehangouts and #hubble ) and you can always leave comments on this event page and the YouTube Video.

  65. Citizen Science: Update on the Stadate: M83 Project


    Last January, Stardate: M83 was launched on +The Zooniverse

    This joint project was designed to enlist citizen scientists to help uncover the ages of star clusters in the Southern Pinwheel Galaxy.

    It is possible to estimate the age of a star cluster based on its appearance and since humans are very good at seeing these sorts of details, participants will be helping STScI astronomers identify which of the clusters in the Southern Pinwheel Galaxy (M83) have clouds of hydrogen gas around it.

    So, after six week, how did it go? What did the astronomers learn?

    Please join +Tony Darnell as he discusses the success of the project and what is coming next.

    As an added bonus, we've invited the top 10 citizen science classifiers to acknowledge their contributions and get their feedback.

    We will have the Q&A app running during the event and we also encourage you to ask any questions or comments here on this event page or use twitter and the hashtags #hubble and #hubblehangout.

    Hope to see you there!

  74. What Are Hubble's Greatest Images?

    Since 1990, the Hubble Space Telescope has been expanding our knowledge of the universe in ways that were never anticipated and has helped us answer questions we hadn't even thought to ask.

    The images that have been sent from this perch high in orbit around the Earth have provided us with unprecedented views of the cosmos.

    So, we started wondering: which images were the best? Which images have provided the most important contribution to our understanding of the universe? Which ones were the most beautiful?

    HubbleSite is scheduled to post a best-of-Hubble image collection within our Gallery by Summer's end – a slideshow we're calling "Hubble's Top Shots." We are aiming to provide a group of at least 100 images based both on scientific significance and aesthetics/popularity.
