In celebration of Hubble's 25th Anniversary, we not only released an eye-popping star cluster image, but took it into a new dimension with a spectacular visualization.
May 4th is Star Wars Day and a great excuse to discuss the celestial lightsabers of Herbig-Haro Object HH 24.
Einstein's general theory of relativity was proposed a century ago and has been confirmed in many ways. The existence of gravitational waves was the last major unverified prediction of general relativity, until now.
Twenty years later, Hubble revisits the iconic pillars in the Eagle Nebula and reveals new details, new features, and new infrared views.
Through gravitational lensing, one can see the effects of gravity in Hubble images.
The new film "The Martian," by one of my favorite directors, doesn't dissapoint by both theatrical and scientific standards.
Hubble kicked off its 25th anniversary year with two stunning new views of the pillars in the Eagle Nebula.
2015 marks the 25th anniversary of the launch of the Hubble Space Telescope, and we are celebrating the remarkable history, ground-breaking discoveries, and awesome imagery of perhaps the most important telescope ever.
Gravitational lensing takes the common ideas of a glass lens and transforms them to cosmic proportions.
What happens when a massive distortion in space-time comes to Baltimore's Inner Harbor for a crab feast? OK, we haven't got that crab part, but we can show you the visual distortions due to gravitational lensing.
The most distant objects Hubble has seen are just over 13 billion light-years away.
The visual distortions of gravitational lensing can be demonstrated using scientific simulations.
Gravitational lensing provides unmistakable and visually striking evidence for Einstein's general theory of relativity.
Einstein's general relativity uses the strange notion of curved space to reinterpret gravity, and explains things that Newton's version of gravity can't.
In a playful explanantion of the ways comets are named, I've adapted T. S. Eliot's poem "The Naming of Cats" for my own celestial purposes.
The first images of Comet ISON taken from Mars are in. While they aren't spectacular to look at, they are scientifically quite useful.
While Comet ISON may or may not develop into a spectacular sight from Earth, it most certainly will provide some intriguing observations from Mars.
The edge of interstellar space and the borderline of the solar system sound like the same thing, but they are widely separated boundaries.
Solar eclipses are, in general, really cool events. But when NASA captures a solar eclipse from Mars, that's in the realm of awesomely amazing.
For Hubble's 23rd anniversary, we released a gorgeous new view of the Horsehead Nebula using infrared light. This episode explores not only the scientific story behind the image, but also the process of creating a three-dimensional model and flight into the glowing gaseous landscape of the nebula.
