Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, six or more years of data from NASA’s Fermi Gamma-ray Space Telescope has broadened the mission’s dark matter hunt using some novel approaches.
Researchers using NASA’s Fermi Gamma-ray Space Telescope have discovered the first gamma-ray pulsar in a galaxy other than our own. Known as PSR J0540-6919, the object sets a new record for the most luminous gamma-ray pulsar known. The pulsar lies in the outskirts of the Tarantula Nebula in the Large Magellanic Cloud, a small galaxy that is located 163,000 light-years away.
