This is a surprising finding as astronomers had expected that the light curve would not only continue decreasing but even experience a sharp drop, rather than flattening into a plateau. The discovery ...

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 ...

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 ...

Kepler's supernova remnant is extremely exciting for astronomers – a rare example of a supernova for which we have a clear ...

Type Ia supernovae result from a white dwarf exceeding 1.4 solar masses after accreting hydrogen from a companion star, leading to a thermonuclear explosion. The Sirius system contains a white dwarf ...

NASA's James Webb Space Telescope (JWST) has made a remarkable discovery after identifying a new type of supernova. Astronomers from the Space Telescope Science Institute (STScI) made it possible.

A unique dataset of Type Ia Supernovae being released today could change how cosmologists measure the expansion history of the Universe. A unique dataset of Type Ia Supernovae being released today ...

Berkeley Lab astrophysicist Peter Nugent, working with Adam Riess of the Space Telescope Science Institute, used an IBM SP supercomputer at NERSC to analyze data from an exploding star that had been ...
