New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

A rare gravitationally lensed supernova called SN 2025wny appears in five separate images due to the gravity of two ...

An international team of astronomers has carried out photometric and spectroscopic observations of SN 2024abvb—a recently ...

This week the telescope revealed its first real-time sky alerts, issuing 800,000 alerts for transient events in just one night, February 24, 2026. Some of these were variable stars – which go through ...

NASA has detected a precursor or progenitor to a supernova for the first time – and it's all thanks to old photos.

Supernovae, the explosive deaths of stars, are some of the universe's biggest bursts of energy and light. When they erupt, one supernova can shine even brighter than an entire galaxy. It's a fitting ...

Exploding stars in near-solar space may have triggered at least two mass extinction events in Earth's history. An analysis of the frequency of supernova explosions in the Milky Way, led by ...

It’s easy to forget that stars, just like us, have lifetimes. They’re born, they live, and eventually, they die. And for some stars, their death is dramatic, producing an explosion so powerful it can ...

Researchers from the University of Colorado Boulder have found that the rings in Earth's ancient trees may hold evidence detailing the death of massive stars, known as supernovae, throughout space.
