GLAST, which will scan the heavens for high energy bursts, and perhaps help solve the mystery of dark matter, has successfully launched according to Wired. A nice graphic illustrating the electromagnetic spectrum accompanies the article.
After a 75-minute flight, the GLAST spacecraft was deployed into low Earth orbit. It will begin to transmit initial instrument data after about three weeks. The telescope will explore the most extreme environments in the universe, searching for signs of new laws of physics and investigating what composes mysterious dark matter. It will seek explanations for how black holes accelerate immense jets of material to nearly light speed, and look for clues to crack the mysteries behind powerful explosions known as gamma-ray bursts.
