A massive star in the Andromeda galaxy brightened in infrared light starting around 2014, then faded from optical view and ...

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 ...

Neutrinos are cosmic tricksters, paradoxically hardly there but lethal to stars significantly more massive than the sun. These elementary particles come in three known "flavors": electron, muon and ...

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 ...

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 ...

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 ...
