       Discover the cosmos! Each day a different image or photograph of our   
         fascinating universe is featured, along with a brief explanation   
                       written by a professional astronomer.

      Image Credit: X-ray - NASA/CXC/SAO, IR - NASA/HST/STScI; Inset: Radio -   
                       Event Horizon Telescope Collaboration   
      
      Explanation: There's a black hole at the center of the Milky Way. Stars   
      are observed to orbit a very massive and compact object there known as   
      Sgr A* (say "sadge-ay-star"). But this just released radio image   
      (inset) from planet Earth's Event Horizon Telescope is the first direct   
      evidence of the Milky Way's central black hole. As predicted by   
      Einstein's Theory of General Relativity, the four million solar mass   
      black hole's strong gravity is bending light and creating a shadow-like   
      dark central region surrounded by a bright ring-like structure.   
      Supporting observations made by space-based telescopes and ground-based   
      observatories provide a wider view of the galactic center's dynamic   
      environment and an important context for the Event Horizon Telescope's   
      black hole image. The main panel image shows the X-ray data from   
      Chandra and infrared data from Hubble. While the main panel is about   
      7-light years across, the Event Horizon Telescope inset image itself   
      spans a mere 10 light-minutes at the center of our galaxy, some 27,000   
      light-years away.
