"Black holes are not the only objects in the universe that spew powerful jets from their poles. Dead, smoldering stars can emit them, too, and the jets they create rival and might even surpass those fired by black holes, scientists find.
The discovery, to be detailed in an upcoming issue of The Astrophysical Journal Letters, shows that the unusual properties of black holes-like the presence of an event horizon and the lack of an actual surface-are not required for jets to form.
"Gravity appears to be the key to creating these jets, not some trick of the event horizon," said study leader Sebastian Heinz of the University of Wisconsin at Madison." - http://www.msnbc.msn.com/id/19461296/
