GLASTcast Episode 2: What are Gamma Rays?

NASA's GLAST mission is an astrophysics and particle physics partnership, developed in collaboration with the U.S. Department of Energy, along with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden, and the U.S.

Somewhere out in the vast depths of space, a giant star explodes with the power of millions of suns. As the star blows up, a black hole forms at its center. The black hole blows two blowtorches in opposite directions, in narrow jets of gamma rays. NASA's Gamma-ray Large Area Space Telescope, or GLAST, will catch about 200 of these explosions, known as gamma-ray bursts, each year. GLAST's detailed observations may give astronomers the clues they need to unravel the mystery of what exactly produces these gamma-ray bursts, which are the brightest explosions in the universe since the Big Bang.
