Astronomy Picture Of the Day (APOD)
The Pipe Dark Nebula
26.05.2002
The dark nebula predominant at the lower left of the above photograph is known as the Pipe Nebula. The dark clouds, suggestively shaped like smoke rising from a pipe, are caused by absorption of background starlight by dust.
A String Of Pearls
25.05.2002
Comet Shoemaker-Levy 9, named after its co-discoverers, was often referred to as the "string of pearls" comet. It is famous for its suggestive appearance as well as its collision with the planet Jupiter!
Love and War by Moonlight
24.05.2002
Venus, named for the Roman goddess of love, and Mars, the war god's namesake, approach each other by moonlight in this lovely sky view recorded on May 14th from Dunkirk, Maryland, USA.
N132D and the Color of X Rays
23.05.2002
Supernova remnant N132D shows off complex structures in this sharp, color x-ray image. Still, overall this cosmic debris from a massive star's explosive death has a strikingly simple horseshoe shape. While N132D lies 180,000 light-years distant in the Large Magellanic Cloud, the expanding remnant appears here about 80 light-years across.
Moon and Planets by the Eiffel Tower
22.05.2002
The great evening grouping of planets is coming to an end. Before all the planets went their own separate directions, however, the Moon was kind enough to pose with some of them. The planets in the above picture, taken last week, are Venus and Jupiter.
The Galactic Center Radio Arc
21.05.2002
What causes this unusual structure near the center of our Galaxy? The long parallel rays slanting across the top of the above radio image are known collectively as the Galactic Center Radio Arc and jut straight out from the Galactic plane.
East of the Lagoon Nebula
20.05.2002
To the east of the Lagoon Nebula is a star field rich in diversity. On the lower left are clouds rich in dark dust that hide background stars and young star systems still forming. Dark clouds include LDN 227 on the left and IC 1275 on the right, with a bright star near its tip.
Saturns Moon Tethys
19.05.2002
Tethys is one of the larger and closer moons of Saturn. It was visited by both Voyager spacecraft - Voyager 1 in November 1980 and by Voyager 2 in August 1981. Tethys is now known to be composed almost completely of water ice. Tethys shows a large impact crater that nearly circles the planet.
Andromeda Island Universe
18.05.2002
How far can you see? The most distant object easily visible to the unaided eye is M31, the great Andromeda Galaxy some two million light-years away. Without a telescope, even this immense spiral galaxy appears as an unremarkable, faint, nebulous cloud in the constellation Andromeda.
Gamma Ray Burst, Supernova Bump
17.05.2002
On the 21st of November 2001, satellites detected yet another burst of gamma-rays from the cosmos. While this flash of high-energy photons lasted for less than a minute, eager astronomers have been following the fading optical light from the location of the burst source ever since.
