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 ...

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 ...

Type Ia supernovae are stellar explosions used to measure the universe's expansion. These explosions result from white dwarfs exceeding a critical mass, causing them to reignite and explode. Two ...

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 ...

A team of astronomers has discovered the fastest optical flash of a Type Ia supernova, and reports a study in the Astrophysical Journal Letters published on December 8. Many stars end their lives ...

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 ...

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

Astronomers find an explanation for the fastest stars in the galaxy while uncovering a new mechanism for a supernova explosion. Credit: Technion illustration Astronomers call a special kind of ...

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 ...
