Once charted as a 'guest star' in ancient China, dreaded as a harbinger of ill omens in medieval Europe, and preserved in the ...

Despite being so elusive, neutrinos are produced in abundance in some of the most violent events in the universe. One of their strangest properties is that they can spontaneously switch between three ...

It's like a baby Big Bang. The post Scientists Propose That Entire Universes Can Form Inside Collapsing Stars appeared first ...

Left Panel: When neutrinos scatter with themselves via standard model interactions the collapsing core of the massive star is relatively cold, and the neutrinos are mostly all electron flavor. In this ...

A supergiant star, lying 2.5 million light-years away in the Andromeda galaxy, ended its life without a bang and then turned itself quietly into a black hole. Unlike massive stars that explode as ...

A dying massive star does not go quietly. Its core collapses, matter crashes inward, neutrinos pour out in staggering numbers, and somewhere in that turmoil the blast either rebounds into a supernova ...

Astronomers have glimpsed the inner structure of a dying star in a rare kind of cosmic explosion called an “extremely stripped supernova”. In a paper published today in Nature, Steve Schulze of ...

Massive stars nearing the end of their lives typically undergo core collapse, releasing neutrinos that can drive a shock strong enough to eject their outer layers and create a supernova. But if the ...
