Astronomy Week: Monsters in the Cosmic Sea

Black Hole Tales From the Edge of Space & Time, Presented by Shane Larson, CIERA Northwestern University at the Sunriver Nature Center/Observatory.  Learn about blackholes, whose gravity is so strong not even light can escape.  Once thought to be science fiction, astronomers have discovered they are very common in the Universe.  The fact that they are common does not change their strangeness!  They bend space and time and can shred stars into nothing.
