Fermi Maps an Active Galaxy's 'Smokestack Plumes'
04.01.10 - If our eyes could see radio waves, the nearby galaxy Centaurus A would be one of the biggest and brightest objects in the sky, nearly 20 times the apparent size of a full moon.

NASA's Fermi Probes "Dragons" of the Gamma-ray Sky
03.02.10 - Fermi reveals that most extragalactic gamma radiation comes from unknown sources rather than from black-hole-powered jets from active galaxies—what astronomers once considered the most likely suspects.
-
NASA's Fermi Closes on Source of Cosmic Rays
02.16.10 - New images of supernova remnants from NASA's Fermi Telescope bring astronomers a step closer to understanding the source of some of the universe's most energetic particles -- cosmic rays.
