Black Hole, Nasa | featured news

Using NASA's Fermi Gamma Ray Space Telescope, scientists were able to detect the light of the earliest stars, which are now long since gone... One of the primary goals of the Fermi Gamma Ray Space Telescope is to measure the starlight in the universe and use that to figure out how much light has ever shone in it. Yesterday, astronomers on Fermi’s research team announced that they have reached that goal.

For years, astronomers have known about the supermassive black hole at the center of our Milky Way galaxy, but these pictures from NASA's NuSTAR telescope show a rare view of the usually sleeping giant gobbling down a cosmic snack.

NASA is poised to launch its latest X-ray space telescope on a two-year hunt for hard-to-see objects lurking in the heart of the Milky Way and other galaxies.
