As the most energetic photons, gamma rays are rare, difficult to observe, require special telescopes & detectors, and not many of them make it to the surface of the earth anyway. So why is gamma ray astronomy important?

Its not an area of astronomy that amateurs usually dip even their big toe in and something entirely new for me. Talking jointly with a Dr Stella Bradbury and Dr Joachim Rose at the department of Physics was a little scary, but turned out to be extremely informative. They spoke about their work at many observatories, including Veritas Array. I spoke to them a couple of weeks ago and you will hear the reference to the launch of Gamma Ray Large Area Telescope (GLAST). That launch has been delayed to June 3rd.
