Astronomy Picture Of the Day (APOD)
Aurora Over Antarctica
20.03.2002
Looking out from the bottom of the world, strange and spectacular sights are sometimes observed. Such was the case during the long Antarctic night of 1998, as awesome aurora sub-storms were photographed above scientific outposts. Visible in the left foreground of the above photograph is the Martin A.
Breaking Distant Light
19.03.2002
In the distant universe, time appears to run slow. Since time-dilated light appears shifted toward the red end of the spectrum (redshifted), astronomers are able to use cosmological time-slowing to help measure vast distances in the universe.
Comet Ikeya-Zhangs Busy Tail
18.03.2002
One of the brightest comets of the past five years will likely reach its peak brightness this week. Comet Ikeya-Zhang, officially known as C/2002 C1, can now be seen without aide from a dark location above the western horizon shortly after sunset.
NGC 2244: A Star Cluster in the Rosette Nebula
17.03.2002
In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula. The stars of NGC 2244 formed from the surrounding gas only four million years ago and emit light and wind that define the nebula's appearance today.
The Colorful Moon
16.03.2002
Do you recognize the Earth's Moon when you see it? The crazy, patchwork appearance of the false-color image makes this almost full view of the Moon's familiar near side look very strange.
Neutron Mars
15.03.2002
Looking for water on Mars, researchers using detectors on board the orbiting Mars Odyssey spacecraft have created this false-color global map of energetic neutrons from the otherwise Red Planet. What do neutrons have to do with water?
SM3B: Mission to Hubble
14.03.2002
Now complete, Servicing Mission 3B (SM3B) was really the fourth trip to the Hubble Space Telescope, as the originally planned mission 3 was split into two parts. Falling around planet Earth, about 320 nautical...
LL Orionis: When Cosmic Winds Collide
13.03.2002
This arcing, graceful structure is actually a bow shock about half a light-year across, created as the wind from young star LL Orionis collides with the Orion Nebula flow. Adrift in Orion's stellar...
Atete Corona on Venus
12.03.2002
What could cause a huge cylindrical mountain to rise from the surface of Venus? Such features that occur on Venus are known as coronas. Pictured above in the foreground is 500-kilometer wide Atete Corona found in a region of Venus known as the Galindo.
The 100 Meter Green Bank Radio Telescope
11.03.2002
The largest single-dish fully steerable radio telescope began operation in 2000 August in Green Bank, West Virginia, USA. Dedicated as the Robert C. Byrd Green Bank Telescope, the device weighs over 30 times more than the Statue of Liberty, and yet can point anywhere in the sky more precisely than one thousandth of a degree.
