       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.

      Explanation: What happens if a star gets too close to a black hole? The   
      black hole can rip it apart -- but how? It's not the high gravitational   
      attraction itself that's the problem -- it's the difference in   
      gravitational pull across the star that creates the destruction. In the   
      featured animated video illustrating this disintegration, you first see   
      a star approaching the black hole. Increasing in orbital speed, the   
      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 accretion disk. The animation then   
      takes you into the accretion disk while looking toward the black hole.   
      Including the strange visual effects of gravitational lensing, you can   
      even see the far side of the disk. Finally, you look along one of the   
      jets being expelled along the spin axis. Theoretical models indicate   
      that these jets not only expel energetic gas, but also create energetic   
      neutrinos -- one of which may have been seen recently on Earth.
