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 ...

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 ...

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 ...

Artist’s drawing of SN 2021yfj. Having lost its outer layers, the dying star was left with only a core of oxygen, sulfur and silicon (bright center dot) but continued to experience extreme mass loss ...

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 ...

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

(CNN) — Astronomers have observed what they are calling a new type of supernova, which has provided an unparalleled glimpse into what happens deep within a star just before it explodes. A study ...

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 ...

Somewhere in the night sky, a massive star is nearing the end of its life. Astronomers believe it could erupt into a ...

WASHINGTON (Reuters) -Astronomers have observed the calamitous result of a star that picked the wrong dance partner. They have documented what appears to be a new type of supernova, as stellar ...
