9/6/2003 STScI-2003-25 43. Farthest, Faintest Solar System Objects Found Beyond Neptune Astronomers using NASA's Hubble Space Telescope have discovered three of the faintest and smallest objects ever detected beyond Neptune. (More)
9/5/2003 STScI-2003-26 44. Hubble Assists Rosetta Comet Mission Results from NASA's Hubble Space Telescope played a major role in preparing ESA's ambitious Rosetta mission for its new target, comet 67P/Churyumov-Gerasimenko (67P/C-G). (More)
8/27/2003 STScI-2003-22 45. Mars: Closest Encounter These two images, taken 11 hours apart with NASA's Hubble Space Telescope, reveal two nearly opposite sides of Mars. Hubble snapped these photos as the red planet was making its closest approach... (More)
5/15/2003 STScI-2003-17 46. Brighter Neptune Suggests a Planetary Change of Seasons Springtime is blooming on Neptune! This might sound like an oxymoron because Neptune is the farthest and coldest of the major planets. But observations... (More)

10/7/2002 STScI-2002-17 47. Hubble Spots an Icy World Far Beyond Pluto NASA's Hubble Space Telescope has measured the largest object discovered in the solar system since the discovery of Pluto 72 years ago. Approximately... (More)
4/17/2002 STScI-2002-04 48. Hubble Hunts Down Binary Objects at the Fringe of Our Solar System The Hubble Space Telescope is hot on the trail of a puzzling new class of solar system object that might be called a Pluto "mini-me."... (More)

10/11/2001 STScI-2001-31 49. Scientists Track "Perfect Storm" on Mars A pair of eagle-eyed NASA spacecraft — the Mars Global Surveyor (MGS) and Hubble Space Telescope — are giving amazed astronomers a ringside seat to the biggest... (More)
7/5/2001 STScI-2001-24 50. Hubble Captures Best View of Mars Ever Obtained From Earth Frosty white water ice clouds and swirling orange dust storms above a vivid rusty landscape reveal Mars as a dynamic planet in this sharpest... (More)
6/7/2001 STScI-2001-15 51. A Change of Seasons on Saturn Looming like a giant flying saucer in our outer solar system, Saturn puts on a show as the planet and its magnificent ring system nod majestically over the course of its 29-year... (More)
5/17/2001 STScI-2001-14 52. Astronomers Puzzled over Comet LINEAR's Missing Pieces Astronomers analyzing debris from a comet that broke apart last summer spied pieces as small as smoke-sized particles and as large as football-field-sized fragments. (More)

12/14/2000 STScI-2000-38 53. Satellite Footprints Seen in Jupiter Aurora In this Hubble telescope picture, a curtain of glowing gas is wrapped around Jupiter's north pole like a lasso. This curtain of light, called an aurora, is produced when high-energy... (More)
9/14/2000 STScI-2000-31 54. Centaur's Bright Surface Spot Could be Crater of Fresh Ice The unexpectedly varied surface of a wayward piece of space debris has given astronomers new insights into the characteristics and behavior of a ghostly... (More)
8/7/2000 STScI-2000-27 55. Hubble Discovers Missing Pieces of Comet Linear To the surprise and delight of astronomers, the Hubble telescope discovered a small armada of "mini-comets" left behind from what some scientists had prematurely thought... (More)
7/28/2000 STScI-2000-26 56. Hubble Sees Comet Linear Blow its Top Lackluster comet LINEAR (C/1999 S4) unexpectedly threw astronomers a curve. Using the Hubble telescope, researchers were surprised to catch the icy comet in a brief, violent... (More)

8/5/1999 STScI-1999-29 57. Hubble Views Ancient Storm in the Atmosphere of Jupiter When 17th-century astronomers first turned their telescopes to Jupiter, they noted a conspicuous reddish spot on the giant planet. (More)
6/30/1999 STScI-1999-27 58. A Closer Encounter with Mars Taking advantage of Mars's closest approach to Earth in eight years, astronomers using the Hubble telescope have taken the space-based observatory's sharpest views yet of the Red Planet. (More)
5/19/1999 STScI-1999-22 59. Colossal Cyclone Swirls near Martian North Pole Astronomers using the Hubble telescope have discovered an enormous cyclonic storm system raging in the northern polar regions of the planet Mars. (More)
4/20/1999 STScI-1999-13 60. Hubble Clicks Images of Io Sweeping across Jupiter While hunting for volcanic plumes on Io, the Hubble telescope captured these images of the volatile moon sweeping across the giant face of Jupiter. (More)
