BERKELEY, CA — A group of scientists affiliated with the SuperNova Legacy Survey (SNLS) have found startling evidence that there is more than one kind of Type Ia supernova, a class of exploding stars ...

A team of astronomers led by The University of Texas at Austin’s Howie Marion has detected a flash of light from the companion to an exploding star. This is the first time astronomers have witnessed ...

A new study from NASA reveals that a supernova observed nearly two millennia ago expanded inside a pre-formed cosmic cavity, ...

NASA’s Imaging X-ray Polarimetry Explorer, known as IXPE, has produced the first spatially resolved polarization maps of the supernova remnant RCW 86, the shell of debris left by what is likely the ...

For the first time, astronomers have observed radio waves emitted by a Type Ia supernova, a type of explosion originating from a white dwarf star. This provides important clues to understand how white ...

The ‘guest star’ of 185 AD has been one of astronomy's most unresolved cases for over 1800 years. Ancient Chinese chroniclers ...

Type Ia supernovae represent the dramatic thermonuclear explosions of white dwarf stars, typically triggered in binary systems by processes such as accretion from a companion or the merger of two ...

Add Yahoo as a preferred source to see more of our stories on Google. The striking object appeared as bright as Saturn in the vicinity of the constellation Cassiopeia, and historical chronicles from ...

Ironically, to study dark energy — a murky, unknown something that seems to act as an accelerant for our universe’s expansion — astronomers rely on brilliant supernovae. From 2013 to 2019, the Dark ...

It’s easy to forget that stars, just like us, have lifetimes. They’re born, they live, and eventually, they die. And for some stars, their death is dramatic, producing an explosion so powerful it can ...
