Pretty much awesome. But a year? Hmm, let's cross our fingers!

The <A href="http://fermi.gsfc.nasa.gov">Fermi Gamma-ray Space Telescope</A> could detect the telltale signs of dark-matter annihilation in as little as a year, if calculations by UK and US astrophysicists prove correct.

The calculations, which are the first to take into account the relative velocities of dark-matter particles, suggest that dark-matter annihilation is many times more prevalent than has been predicted before. If this is true, the annihilations could be producing enough gamma rays to expose several clumps or “subhaloes” of dark matter in Fermi’s first year of data collection alone.
