With funds for mega accelerator projects drying up, particle physicists are increasingly turning their attention heavenwards. A 15-institution collaboration at Stanford Linear Accelerator Center in US has proposed a US $100 million gamma ray telescope -Gamma Large Array Space Telescope (GLAST) - to be put into space by AD 2005.

GLAST will record gamma rays from space with a much improved sensitivity. This could provide insights into gamma ray-emitting active galaxies.
