Astronomy Picture Of the Day (APOD)
Cosmic Construction Zone RCW 49
3.06.2004
Stars and planets appear to be under construction in dusty nebula RCW 49. This Spitzer Space Telescope false-color infrared view of the nearby stellar nursery shows that known, hot stars are well on their way to clearing out the nebula's central regions.
The Colorful Clouds of Rho Ophiuchi
2.06.2004
The many spectacular colors of the Rho Ophiuchi (oh'-fee-yu-kee) clouds highlight the many processes that occur there. The blue regions shine primarily by reflected light. Blue light from the star Rho Ophiuchi and nearby stars reflects more efficiently off this portion of the nebula than red light.
The Supergalactic Wind from Starburst Galaxy M82
1.06.2004
Star formation occurs at a faster pace in M82 -- a galaxy with about ten times the rate of massive star birth (and death) compared to our Milky Way. Winds from massive stars and blasts from supernova explosions have created a billowing cloud of expanding gas from this remarkable starburst galaxy.
24 Million Kilometers to Saturn
31.05.2004
Next stop: Saturn. The Cassini-Huygens spacecraft is approaching Saturn and will fire its engines to break into orbit around the ringed giant on July 1. The robot spacecraft was launched in 1997 and rounded Jupiter in 2001.
Astronaut at Work
30.05.2004
Did you ever have a day where everything got turned around and you just couldn't tell which way was up? Fortunately, this didn't happen to astronaut James S. Voss on 2000 May 21, who spent six hours preparing to fix and upgrade the International Space Station.
Cone Nebula Close Up
29.05.2004
Cones, pillars, and majestic flowing shapes abound in stellar nurseries where natal clouds of gas and dust are buffeted by energetic winds from newborn stars. A well-known example, the Cone Nebula within the bright galactic star-forming region NGC 2264, was captured in this close-up view from the Hubble Space Telescope's Advanced Camera for Surveys.
A Manhattan Sunset
28.05.2004
Today, if it is clear, Manhattan will flood dramatically with sunlight just as the Sun sets precisely on the centerline of every street. Usually, the tall buildings that line the gridded streets of New York City's tallest borough will hide the setting Sun.
Two Comets in Southern Skies
27.05.2004
Wielding a very wide-angle lens, astronomer Gordon Garradd was able to capture two naked-eye comets in one picture looking toward the west from Loomberah, New South Wales, Australia. At the far left lies comet C/2002 T7 (LINEAR) and at the far right, comet C/2001 Q4 (NEAT).
At the Summit of Olympus Mons
26.05.2004
From martian orbit, the Mars Express cameras looked down on the largest volcano in the solar system. The result was this stunningly detailed overhead view of the caldera or summit crater region of Olympus Mons.
Moon Between the Stones
25.05.2004
Despite clouds and rain showers astronomer Phillip Perkins managed to spot a reddened, eclipsed Moon between the stones of this well known monument to Sun during May's total lunar eclipse, from Stonehenge, England.
