Oldest Super Nova Explosion discovered

From the Daily Galaxy magazine:

• Astronomers have discovered the oldest and farthest supernova ever detected -- a massive star that exploded 11 billion years ago.
• Prior to this discovery, NASA’s Swift Observatory had detected a 13-billion-year-old gamma-ray burst.... but this latest discovery marks the first confirmation of a full-on star explosion.

First thing this shows is that the first 2 billion years, the Universe was a VERY busy place. It was a hot dense and inhospitable as you could imagine.
