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 ...

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 ...

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 ...

So, instead, supernovae are categorized by observed characteristics such as the light curves of how they brighten and fade ...

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 ...

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 ...

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 ...
