Astronomers glimpse supernova shockwave

Astronomers have captured the earliest minutes of two exploding stars and for the first time seen a shockwave generated by a star's collapsing core.

Rare supernova discovery ushers in new era for cosmology

With the help of an automated supernova-hunting pipeline and a galaxy sitting 2 bil-lion light years away from Earth that's acting as a "magnifying glass,'' astronomers have captured multiple images of a Type Ia supernova—the ...

Distant supernova split four ways by gravitational lens

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.

Electron-eating neon causes star to collapse

An international team of researchers has found that neon inside a certain massive star can consume the electrons in the core, a process called electron capture, which causes the star to collapse into a neutron star and produce ...
