Astronomy Picture Of the Day (APOD)
Planets Over Stonehenge
9.05.2002
Stonehenge, four thousand year old monument to the Sun, provides an appropiate setting for this delightful snapshot of the Sun's children gathering in planet Earth's sky. While the massive stone structure dates from around 2000 B.C.
Sunspot Loops in Ultraviolet
8.05.2002
It was a quiet day on the Sun. The above image shows, however, that even during off days the Sun's surface is a busy place. Shown in ultraviolet light, the relatively cool dark regions have temperatures of thousands of degrees Celsius.
Smog Over New York
7.05.2002
What is not pretty about the above picture? In a word: smog. In 2000 October the orbiting Space Shuttle Discovery photographed update New York just at sunset. Visible is golden sunlight reflecting from two of the Great Lakes (Erie and Ontario), and several of the Finger Lakes.
NGC 4676: When Mice Collide
6.05.2002
These two galaxies are pulling each other apart. Known as "The Mice" because they have such long tails, each spiral galaxy has likely already passed through the other and will probably collide again and again until they coalesce.
The M7 Open Star Cluster in Scorpius
5.05.2002
M7 is one of the most prominent open clusters of stars on the sky. The cluster, dominated by bright blue stars, can be seen with the naked eye in a dark sky in the tail of the constellation of Scorpius.
The Moons of Earth
4.05.2002
While orbiting the planet during their June 1998 mission, the crew of the Space Shuttle Discovery photographed this view of two moons of Earth. Thick storm clouds are visible in the lovely blue planet...
Cone Nebula Close Up
3.05.2002
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 newest camera.
Arp 188 and the Tadpole s Tidal Tail
2.05.2002
In this stunning vista recorded with the Hubble Space Telescope's new advanced camera, distant galaxies form a dramatic backdrop for disrupted spiral galaxy Arp 188, the Tadpole Galaxy. The cosmic Tadpole is a mere 420 million light-years distant toward the northern constellation Draco.
In the Center of the Omega Nebula
1.05.2002
In the depths of the dark clouds of dust and molecular gas known as the Omega Nebula, stars continue to form. The above image from the Hubble Space Telescope's newly installed Advanced Camera for Surveys shows unprecedented detail in the famous star-forming region.
The Holographic Principle
30.04.2002
Is this image worth a thousand words? According to the Holographic Principle, the most amount of information you can get from this image is about 3 x 1065 bits for a normal sized computer monitor.
