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 ...

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 ...

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 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 ...

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 ...

An international team of astronomers has conducted detailed multicolor photometric and spectroscopic observations of SN 2022xlp—a type Iax supernova. Results of the observational campaign, published ...

Scientists have turned to artificial intelligence (AI) to better understand why some dead stellar remnants called white dwarf stars explode. However, despite the significance of Type Ia supernovas in ...

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 ...

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 ...

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 ...

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 ...
