A key mystery about Type Ia supernovas is that, in the dominant theory known as D6, a white dwarf would need a companion star ...

Most stars in the Milky Way move at steady speeds, orbiting the galactic center in regular paths. But astronomers have ...

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 ...

In a breakthrough study published in Nature Astronomy, researchers have discovered a new origin for some of the fastest stars ...

A unique dataset of Type Ia Supernovae being released today could change how cosmologists measure the expansion history of the Universe. Dr Mathew Smith and Dr Georgios Dimitriadis from Lancaster ...

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 ...

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 ...
