Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Stereo Phobos
Explanation: Get out your red/blue glasses and float next to Phobos, grooved moon of Mars! Also featured in yesterday's episode , the image data from the Mars Express High Resolution Stereo Camera was recorded at a distance of about 200 kilometers. This tantalizing stereo anaglyph view shows the Mars-facing side of the asteroid-like moon's cratered and grooved surface. Up to hundreds of meters wide, the mysterious grooves may be fractures related to the impact which created 10 kilometer wide Stickney crater , the large crater at the left.
