Simulation of a Type Ia supernova in which material ejected from the explosion (red) runs into a companion star (blue). This collision adds extra ultraviolet light to the supernova as viewed from ...

Researchers have found white dwarf stars with masses close to the maximum stable mass (called the Chandrasekhar mass) are likely to produce large amounts of manganese, iron, and nickel after it orbits ...

Supernovae are the most spectacular fireworks in the universe. Just one such explosion can briefly outshine the rest of the stars in a galaxy combined. Astronomers have become adept at spotting these ...

The 2-m aperture Chinese Space Station Telescope (CSST), which observes at wavelengths ranging from 255 to 1000 nm, is expected to start science operations in 2024. An ultra-deep field observation ...

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 ...

For the first time, astronomers have obtained visual evidence that a star met its end by detonating twice. By studying the centuries-old remains of supernova SNR 0509-67.5 with the European Southern ...

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 ...

Lots of things out in the universe can cause a supernova, from the gravitational collapse of a massive star, to the collision ...

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 ...
