Astronomers may have misread cosmic acceleration for 27 years. The universe may be slowing down, not speeding up.

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

Is there anything more dramatic than an exploding star? More than just extraordinarily bright, energetic events that can ...

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 ...

Astronomers have detected the most distant and biggest black hole flare ever seen, the result of a black hole ripping apart ...

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 ...

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

Supernova remnants, stellar nurseries and more populate the new edge-on view of the Milky Way as seen from Earth’s southern hemisphere.

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 ...

The cataclysmic explosion that spawned the supernova remnant simultaneously gave rise to a superdense pulsar, which was ...

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