CAPE CANAVERAL, Fla. (Associated Press) - NASA launched a telescope Wednesday to scout out elusive, super high-energy gamma rays lurking in the universe. Glast - a NASA acronym standing for Gamma-ray Large Area Space Telescope - began its five- to 10-year Earth-orbiting mission with a midday blastoff aboard a Delta rocket.
The $690 million telescope, supported by six countries, will pick up where NASA's Compton Gamma Ray Observatory left off before its deliberate destruction in 2000, but in a bigger and better way.
With superior new technology and insight gained from Compton and other telescopes, Glast will be able to do in three hours, or two orbits of Earth - survey the entire sky - what Compton took 15 months to do. What's more, Glast and its particle detectors are much more sensitive and precise, and should provide an unprecedented view into the high-energy universe from a 345-mile-high orbit.

PODCASTS: Expanding With the Cosmos
Using the Atacama Cosmology Telescope (ATC), a 6.5-meter microwave collector in Chile, cosmologists are piecing together the early history of the known universe. In an exclusive American Scientist interview, Arthur Kosowsky—a member of the ATC team and a professor in the Department of Physics and Astronomy at the University of Pittsburgh—discusses how he is using ATC to reach back in time billions of years to search for gravitational waves that could verify inflation and reveal unprecedented details about how the cosmos was born.
