X Ray Mystery in RCW 38
26.12.2002
A mere 6,000 light-years distant and sailing through the constellation Vela, star cluster RCW 38 is full of powerful stars. It's no surprise that these stars, only a million years young with hot outer atmospheres, appear as point-like x-ray sources dotting this x-ray image from the orbiting Chandra Observatory.
Searching for Meteorites in Antarctica
25.12.2002
Where is the best place on Earth to find meteorites? Although meteors fall all over the world, they usually just sink to the bottom of an ocean, are buried by shifting terrain, or are easily confused with terrestrial rocks.
Orion Rising
24.12.2002
Orion always comes up sideways ... and was caught in the act earlier this month by astronomer Jimmy Westlake, stargazing eastward over the Rocky Mountains north of Leadville, Colorado, USA. To make this gorgeous image, Westlake placed his camera on a tripod for two exposures.
Spring Dust Storms at the North Pole of Mars
23.12.2002
Spring reached the north pole of Mars in May, and brought with it the usual dust storms. As the north polar cap begins to thaw, a temperature difference occurs between the cold frost region and recently thawed surface, resulting in swirling winds between the adjacent regions.
Stars and Dust Through Baades Window
22.12.2002
Billions of stars light up the direction toward the center of our Galaxy. The vast majority of these stars are themselves billions of years old, rivaling their home Milky Way Galaxy in raw age. These stars are much more faint and red than the occasional young blue stars that light up most galaxies.
Summer at the South Pole
21.12.2002
The December solstice brings the beginning of Winter to Earth's Northern Hemisphere and Summer time to the South! This view of Earth's Southern Hemisphere near the beginning of Summer was created using images from the Galileo spacecraft taken during its December 1990 flyby of our fair planet.
Solstice Celebration
20.12.2002
Aloha and Season's greetings! On December 22nd, at 01:14 Universal Time (December 21, 3:14pm Hawaii-Aleutian Standard Time), the Sun reaches its southernmost point in planet Earth's sky marking the final season change for the year 2002. In celebration, consider this delightfully detailed, brightly colored image of the active Sun.
Colorful Clouds of Orion
19.12.2002
Revisiting one of the most famous nebulae in planet Earth's night sky, astrophotographer Robert Gendler has constructed this stunning, color-enhanced mosiac of the region surrounding the Great Nebula in Orion. As seen here...
RAPTOR Images GRB 021211
18.12.2002
On December 11 astronomers found one of the brightest and most distant explosions in the Universe - a gamma-ray burst - hiding in the glare of a relatively nearby star. The earliest image of the burst's visible light was caught by an earthbound RAPTOR (RAPid Telescopes for Optical Response).
Io Volcano Culann Patera
17.12.2002
What causes the unusual colors surrounding Io's volcanoes? Io, the innermost large moon of Jupiter, is known to be the most tumultuous body in the Solar System. Approximately the size of Earth...
