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.
NASA’s Chandra X-ray Observatory has collected data for over sixteen years on thousands of different objects throughout the universe. Once the data is processed, all of the data goes into an archive and is available to the public. To celebrate American Archive Month, a collection of new images from the Chandra archive has just been released.
