The idea of the hypernova was first proposed by Dr. Bohdan
Paczynski of Princeton University . He wanted to explain the
gamma ray burst s that typically last a few second s at a time,
come from seemingly random directions in space, and have the
potential to produce more energy than anything else in the rest
of the universe for a few seconds. The first remnants of such an
explosion were identified by Q. Daniel Wang of Northwestern
University , using work done by Dr. You-Hua Chu of the
University of Illinois at Urbana-Champaigne as a base. The two
remnants he identified reside in the galaxy M101 in the Ursa
Major Constellation . They have been given the easily memorable
names NGC5471B . The former is a nebula that is expanding at at
least a hundred miles a second while the latter is one of the
largest pieces of supernova wreckage known at 850 light year s
across. Both are about ten times brighter than any known
supernova remnants in our galaxy Little is known for sure about
these powerful explosions, although i
