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, …

Astronomers strike cosmic gold

The first detection of gravitational waves from the cataclysmic merger of two neutron stars, and the observation of visible light in the aftermath of that merger, finally answer a long-standing question in astrophysics: Where do the heaviest elements, ranging from silver and other precious metals to uranium, come from?

Based on the brightness and color of the light emitted following …
