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 ...

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 ...

Starting with the behavior of small flames in the laboratory, a team of researchers has gained new insights into the titanic forces that drive type Ia supernova explosions. These stellar explosions ...

A team of astronomers has discovered the fastest optical flash of a Type Ia supernova. A team of astronomers has discovered the fastest optical flash of a Type Ia supernova, and reports a study in the ...

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 ...

This is a still from a simulation of a Type Ia supernova. In the simulation, a Type Ia supernova explodes (dark brown color). The supernova material is ejected outwards at a velocity of about 10,000 ...
