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 ...

The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. They’re bright enough to see across large ...

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 ...

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 ...

Astronomers know that when a star runs out of fuel and reaches the end of its life, it may go through an epic final stage in which it explodes in a tremendous output of energy called a supernova. But ...
