Imagine the Universe!

Dave Thompson's Featured Image:
A Gamma Ray View of the Moon

EGRET image of the moon

The image is the moon as seen with the EGRET gamma-ray telescope. Although the image has no detail, just seeing the moon in gamma rays reminds me of how unique this field is, because a similar EGRET image of the Sun would be blank. In gamma ray light (and only there), the moon is brighter than the Sun!
