    We've had gamma ray telescopes since the 60s, but todays ones are far more advanced. The Compton Gamma ray obsrrvatory, SWIFT, EGRET, INTEGRAL and GLAST (aka the Fermi Gamma-ray space telescope) are probably the best known, but wikipedia has a fairly comprehensive list: http://en.wikipedia.org/wiki/Category:Gamma-ray_telescopes

    As regards detecting them, we haven't seen any yet, though that is part of GLASTs mission.
