3C321 in 60 Seconds (06-12-2008)
In 3C321, a jet from a black hole in one of the galaxies is pummeling its neighbor galaxy, the first time this type of galactic violence has ever been seen. The jet could bring big trouble for any planets in its path, but could also trigger a burst of star formation in its wake.

The Crab Nebula in 60 Seconds (03-31-2008)
In 1054 A.D., a stars death in the constellation Taurus was observed on Earth. Now, almost a thousand years later, a superdense neutron star left behind by the explosion is spewing out a blizzard of extremely high-energy particles into the expanding debris field known as the Crab Nebula.
