Cosmic explosions known as gamma-ray bursts are curiously picky about where they explode. Shunning spiral galaxies like the Milky Way, gamma-ray bursts prefer to 'go off' in oddball star systems that astronomers are just beginning to understand.

Although the universe contains billions of galaxies, only a small amount of its matter is locked up in these behemoths. Most of the universe's matter that was created during and just after the Big Bang must be found elsewhere.

The components of life may have been under attack in the hostile environments of the universe's first galaxies, say astronomers using NASA's Spitzer Space Telescope.
