Astronomy Picture of the Day

   [1]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.

     [2]An illustration shows a small black dot in the center which is a
   black hole. A red stream or gas arcs in from the top. The black hole is
    also surrounded by a dark and dusty disk. Please see the explanation
                       for more detailed information.

   Explanation: What happens to a star that goes near a black hole? If the
   star directly impacts a massive [5]black hole, then the star falls in
   completely -- and everything vanishes. [6]More likely, though, the star
   goes close enough to have the black hole's gravity pull away its outer
   layers, or [7]disrupt, the star. Then, most of the star's gas does not
   fall into the [8]black hole. These stellar [9]tidal disruption events
   can be as bright as a supernova, and an increasing amount of them are
   being discovered by automated [10]sky surveys. In the [11]featured
   artist's illustration, a star has just passed a massive [12]black hole
   and sheds gas that continues to orbit. The inner edge of a disk of gas
   and dust [13]surrounding the black hole is heated by the [14]disruption
   event and may [15]glow long after the star is gone.
