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.

VIDEO: How Hair Ice Grows
In 2013, American Scientist featured an article on odd ice formations on plant stems, including these curling ribbons of ice. One of the types of ice discussed in the article was hair ice—long, thin strands of ice that grow under quite specific conditions. The only problem is that a new study shows the theory put forth at the time—that gas pressure pushes the water out—isn’t correct... (click the link above to read more).
