Eclipsed Moon in Infrared
10.01.1997

Last September's total lunar eclipse disappointed many observers in the Eastern and Midwestern US who were cursed with cloudy skies.

Working late, tired mission members nicknamed the smooth-looking depression to the left of center in this image from the martian surface, Sleepy Hollow. The picture is a portion of the 3D panorama of the Spirit rover's landing site released yesterday, constructed with data from the Mars rover's navigation cameras.

Mars Through a Small Telescope

What does the surface of asteroid Vesta look like? The brightest asteroid in the Solar System and the object which takes up about 10 percent of the entire mass of the main asteroid belt had never been seen up close before.

High Cliffs Surrounding Echus Chasma on Mars

What created this great cliff on Mars? Did giant waterfalls once plummet through its grooves? With a four-kilometer drop, this high cliff surrounding Echus Chasma, near an impressive impact crater, was carved by either water or lava.
