This revelation means scientists might have to rethink Type II supernova models, which would result in some of these cosmic ...

V Sagittae’s violent mass transfer hints at an imminent nova—and a future supernova visible from Earth. Binary star systems are fairly common in the universe, as are pairs where one star is a compact ...

The V Sge system features a massive star being intensely cannibalized by a dense stellar remnant, likely a white dwarf or a ...

When the two stars eventually smash into each other, the supernova explosion would be visible from Earth, even during daytime.

Betelgeuse is a colossal star that shines brilliantly in the constellation Orion, approximately 600 light-years from Earth. Immense and unstable, this red supergiant is in the final stages of its ...

An unexpected deep-sea deposit may be the smoking gun from a nearby star that exploded as a supernova in the relatively ...

Astronomers observed the fading light of supernova SN 2025kg, which followed the fast X-ray transient (FXT) named EP 250108a.

In a new study, a team of astronomers report that they have captured the most detailed glimpse yet of a red supergiant before it exploded. Using JWST 's powerful infrared vision, the researchers ...

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 ...

Astronomers have identified what appears to be a cosmic smoking gun for a historic supernova explosion, a find that may also help with the search for elusive dark energy in the universe. The new ...

SN2021yfj is a new kind of supernova, challenging our understanding of stellar evolution. Its progenitor lost its outer shells well before the supernova happened and only consisted of its ...

The James Webb Space Telescope has identified an original star that caused a supernova for the first time. Credit: NASA / ESA / CSA / STScI / Charles Kilpatrick / Aswin Suresh Astronomers say they've ...
