The VERITAS (Very Energetic Radiation Imaging Telescope Array System) collaboration, an international team of astronomers from the United States, Canada, United Kingdom and Ireland, has discovered very high energy (VHE) gamma rays emitted by the starburst galaxy M82 (the Cigar Galaxy).
The observed gamma rays have energies more than a trillion times higher than the energy of visible light, and are the highest energy photons ever detected from a galaxy undergoing large amounts of star ...
