This discovery, which is to be reported in a paper to be published in the 28 January 2010 issue of Nature was made by a team, led by Dr. Zsolt Paragi from the Joint Institute for VLBI in Europe (JIVE) in the Netherlands.
The team reports for the first time ever, detection of a relativistic outflow in a Type Ic supernova without a gamma-ray burst. Previously, the only supernova explosions in which such relativistic jets were observed were of the same kind (Type Ic), but produced gamma-ray bursts -- the universe's most luminous explosions, and the supernovae were detected only after and thanks to the gamma-ray bursts.
