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, ...

A new survey maps nearby K-type stars and shows why these long-lived, stable stars are important targets in the search for ...

A team of astronomers has just published a detailed catalog of 2,100 stars, considered as potentially hosting planets ...

Astronomers have observed a white dwarf – a highly compact Earth-sized stellar ember – that is creating a colorful shockwave as it moves through space, leaving them searching for an explanation.The ...

Type Ia supernovae result from a white dwarf exceeding 1.4 solar masses after accreting hydrogen from a companion star, leading to a thermonuclear explosion. The Sirius system contains a white dwarf ...

Are Sun-like stars the only stars where Earth-like worlds exist? This is what a recent study presented this morning at the ...

A pair of rare, compact white dwarf stars that are set to collide in about 23 billion years have been spotted by researchers at the University of Warwick. After converging, the binary star system will ...

New research has shed doubt upon the nature of a distant "dead star" that exists in a binary system with an active stellar companion. Scientists behind the research think this stellar corpse is ...

The sun is the biggest object in the solar system; at about 865,000 miles (1.4 million kilometers) across, it's more than 100 times wider than Earth. Despite being enormous, our star is often called a ...
