Puzzling new supernova may be from star producing antimatter

An exploding star that continued to shine for nearly two years — unlike most supernovae, which fade after a few weeks — is puzzling astronomers and leading theorists, including UC Berkeley astrophysicist Daniel Kasen, to suggest that the event may be an example of a star so hot that it produces antimatter in its core.

Stars would have to be very massive to get this hot, …

Distant Supernova Split Four Ways by Gravitational Lens

From release by Robert Sanders:  "Over the past several decades, astronomers have come to realize that the sky is filled with magnifying glasses that allow the study of very distant and faint objects barely visible with even the largest telescopes.

A University of California, Berkeley, astronomer has now found that one of these lenses …

'Supernova of a generation' discovered by Berkeley scientists

"A supernova discovered yesterday is closer to Earth — approximately 21 million light-years away — than any other of its kind in a generation. Astronomers believe they caught the supernova within hours of its explosion, a rare feat made possible with a specialized survey telescope and state-of-the-art computational tools.

The finding of such a supernova so early and …
