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 ...

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

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

Astronomers observe Type II supernova SN 2024bch behaving differently, with energy from Bowen fluorescence rather than ejecta interaction, challenging models of stellar death and high-energy neutrino ...

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 Hubble Space Telescope may have just celebrated its 35th birthday on April 24, but it's still providing groundbreaking astronomy. Case in point: Astronomers have used Hubble along with an array of ...

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 star exploding at the end of its life has rocked the cosmos like no other that humanity has ever seen. In 2021, astronomers watched in astonishment as a supernova 2.2 billion light-years away named ...

In November 1572, a brilliant new star appeared in the constellation Cassiopeia, shining so brightly that it was visible ...

NASA’s Hubble Space Telescope has identified a star that was one million times brighter than the Sun before it exploded as a supernova in 2005. According to current theories of stellar evolution, the ...

WASHINGTON (Reuters) - When a star up to 20 times the mass of our sun exploded in a nearby galaxy, the blast was so violent that it was visible to the naked eye from Earth's southern hemisphere for ...
