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 ...

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

Photograph of the simulation of a Type Ia supernova explosion in the delayed detonation scenario. After the thermonuclear deflagration flame (purple surface) has burned the inner part of the exploding ...

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 ...

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 ...

Scientists have turned to artificial intelligence (AI) to better understand why some dead stellar remnants called white dwarf stars explode. These energetic explosions, called Type Ia supernovas, ...

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 ...

Ironically, to study dark energy — a murky, unknown something that seems to act as an accelerant for our universe’s expansion — astronomers rely on brilliant supernovae. From 2013 to 2019, the Dark ...

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 ...
