Astronomy Picture Of the Day (APOD)
Red, White, and Blue Sky
4.07.2007
Contrasting colors in this beautiful sunset sky were captured on June 30 from Clear Creek Canyon Observatory in central Arizona, USA. The twilight scene includes brilliant Venus as the evening star, with a bright Saturn just above it, shining through thin clouds.
At the Edge of Victoria Crater
3.07.2007
We're going in. The robotic Opportunity rover currently rolling across Mars has been prowling around the edge of the largest crater it has visited since landing over three years ago. It has been studying Victoria crater and looking for a way in.
Zooming in to the Pelican Nebula
2.07.2007
Where on the sky is the Pelican Nebula? APOD features many objects on the night sky, but usually does not have the resources to show exactly where on the night sky each objects lies.
Steep Cliffs on Mars
1.07.2007
Vertical cliffs of nearly two kilometers occur near the North Pole of Mars. Also visible in the above image of the Martian North Polar Cap are red areas of rock and sand, white areas of ice, and dark areas of unknown composition but hypothesized to be volcanic ash.
Jumbled Galaxy Centaurus A
30.06.2007
At the center of this sharp skyscape, Centaurus A seems to be a fantastic jumble of old yellow stars, young blue star clusters, and imposing dark dust lanes. Spanning over 60,000 light-years, the peculiar elliptical galaxy is apparently the result of a collision of two otherwise normal galaxies.
Cat s Eye Wide and Deep
29.06.2007
The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its more familiar outlines are seen in the the brighter central region of this impressive wide-angle view. But the composite image also combines many short and long exposures to reveal the nebula's extremely faint halo.
A Visit from Atlantis
28.06.2007
This remarkable image of the space shuttle orbiter Atlantis docked with the International Space Station (ISS) was taken at a range of 190 nautical miles. To record the fast moving pair, last week astronomers...
Neon Saturn
27.06.2007
If seen in the right light, Saturn glows like a neon sign. Although Saturn has comparatively little of the element neon, a composite image false-colored in three bands of infrared light highlights features of the giant ringed planet like a glowing sign.
Wisps of the Iris Nebula
26.06.2007
Like delicate cosmic petals, these clouds of interstellar dust and gas have blossomed 1,300 light-years away in the fertile star fields of the constellation Cepheus. Sometimes called the Iris Nebula and dutifully cataloged as NGC 7023, this is not the only nebula in the sky to evoke the imagery of flowers.
The International Space Station Expands Again
25.06.2007
The developing International Space Station (ISS) has changed its appearance again. During the past week, the Space Shuttle Atlantis visited the ISS and added pieces of the Integrated Truss Structure that mirrored those added in September 2006, including a second impressively long array of solar panels.
