"The best-case scenario for axions is Fermi catches a supernova. It's just that the chance of that is small." When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

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

As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the ...

Many space-lovers know the phrase "We are all made of star stuff." And it's true - our planet formed from the dust cloud left ...

Stars like the sun are remarkably constant. They vary in brightness by only 0.1 percent over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep ...

The James Webb Space Telescope is the most powerful instrument scientists have at their disposal to observe the cosmos. Webb has proven this time and time again during its short time in operation.

A long observation with NASA’s Chandra X-ray Observatory revealed important new details of a neutron star that is spewing out a wake of high-energy particles as it races through space. The deduced ...

Stars, like the Sun, are remarkably constant. They vary in brightness by only 0.1 percent over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep ...

Do we live in a supernova graveyard? A team of researchers proposes that 10 million years ago two giant neutron stars crashed into each other and debris from that intense explosion (called kilonova) ...

Gamma rays emerging from neutron stars at the hearts of supernova explosions could solve the mystery of dark matter — in just 10 seconds. That is, if dark matter is composed of axions, which are ...
