Scientists were putting a new space telescope through its paces when they found something odd -- a pulsating star, or pulsar, beaming only in gamma rays. The discovery, published in this week's issue of Science, is the first finding from NASA's Fermi Gamma Ray Space Telescope, which was launched in...

The Chandra X-Ray Observatory has observed a supernova remnant G21.5-0.9, and revealed its ghostly shell. The shell is created by the shockwave ejected by the supernova explosion slamming into material that was shed off earlier by the star.
