A mysterious new kind of cosmic explosion has been spotted by scientists, according to NASA. The baffling blast was detected about 440m light years away in the constellation Aries, on 18 February. Investigators using NASA's space-based Swift Ultraviolet/Optical Telescope say the signal is similar to a gamma-ray burst. However, the phenomenon is much closer and, at over half an hour, lasted 100 times longer than a typical gamma-ray burst.
Rather than portent that the universal cataclysm is nigh, Italian astronomers working on the data have hinted that it may be first view of a supernova from start to finish. Earth-bound amateur astronomers in the northern hemisphere may be able to observe the enigma for themselves next week.

The collapsing star scenario that is one of the leading contenders as the cause of gamma-ray bursts. Dr. Stan Woosley of the University of California at Santa Cruz proposed the collapsar theory in 1993. This artist's concept of the collapsar model shows the center of a dying star collapsing minutes before the star implodes and emits a gamma-ray burst that is seen across the universe.
