Astronomy Picture Of the Day (APOD)Columbia Launches
Rocket engines blazing, the Space Shuttle Columbia arcs into Florida's morning sky after lifting off from pad 39-A at Kennedy Space Center. Seen here in January of 1996, this space shuttle has been...
This panorama of the cratered lunar surface was constructed from images returned by the US Surveyor 6 lander. Surveyor 6 was not the first spacecraft to accomplish a soft landing on the Moon ... but it was the first to land and then lift off again!
A Solar Corona Ejection
The Sun would not be a nice place to spend the summer. One reason, besides the extreme heat, is that explosions are common there. In the above picture, magnetic fields buckle releasing previously constrained hot material from the upper atmosphere of the Sun.
Fields of Minerals on Ganymede
What treasures lie on the surface of Ganymede? Last week, NASA released a map of Jupiter's largest moon made by the Galileo Orbiter highlighting ice and minerals deposits. The leftmost photograph by Voyager...
Elliptical Galaxy NGC 4881 in Coma
Elliptical galaxies are unlike spiral galaxies and hence unlike our own Milky Way Galaxy. The giant elliptical galaxy named NGC 4881 on the upper left lies at the edge of the giant Coma Cluster of Galaxies.
The Coma Cluster of Galaxies
Almost every object in the above photograph is a galaxy. The Coma Cluster of Galaxies pictured is one of the densest clusters known - it contains thousands of galaxies. Each of these galaxies house billions of stars - just like our own Milky Way Galaxy.
The Martian Spring
As spring comes to the northern latitudes of Mars, increased solar heating brings warmth and a change in the weather. The winds produced by the large temperature differences between the receding polar...
Surveyor Night Launch
In early November of 1967, a dramatic night launch of an Atlas Centaur rocket from Cape Canaveral lofted the successful Surveyor 6 spacecraft toward the Moon. The Surveyor series of robotic probes carried out the first US lunar soft landings in preparation for the Apollo program.
Spiral Galaxy NGC 253 Almost Sideways
NGC 253 is a normal spiral galaxy seen here almost sideways. It is the largest member of the Sculptor Group of Galaxies, the nearest group to our own Local Group of Galaxies.
Spiral Galaxy NGC 3628 Edge On
This is what a spiral galaxy looks like sideways. This view of NGC 3628 nearly resembles our own Milky Way Galaxy, which is also known to be a spiral. The dark band across the center is absorbed starlight caused by the galaxy's own interstellar dust.
