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.

                     Animation: Black Hole Destroys Star

   Explanation: What happens if a star gets too close to a black hole? The
   [5]black hole can rip it apart -- but how? It's not the high
   gravitational attraction itself that's the problem -- it's the
   [6]difference in gravitational pull across the star that creates the
   destruction. In the [7]featured animated video illustrating this
   disintegration, you first see a star approaching the black hole.
   Increasing in orbital speed, the [8]star's outer atmosphere is ripped
   away during closest approach. Much of the star's atmosphere disperses
   into deep space, but some continues to orbit the black hole and forms
   an [9]accretion disk. The [10]animation then takes you into the
   accretion disk while looking toward the black hole. Including the
   [11]strange visual effects of [12]gravitational lensing, you can even
   [13]see the far side of the disk. Finally, you [14]look along one of
   the [15]jets being expelled along the spin axis. Theoretical [16]models
   indicate that these jets not only expel energetic gas, but also create
   energetic [17]neutrinos -- one of which may have been [18]seen recently
   on [19]Earth.
