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 ...

"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 ...

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of ...

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

Astronomers have unveiled the largest low-frequency radio color image of the Milky Way ever created, offering a sprawling, ...

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

After a hot, compact neutron star forms from the collapsed iron core of a massive star, axions should be produced in immense quantities for about 10 seconds. Some of these axions (a, red dotted line) ...

Creating a neutron star Before you can get this ideal cosmic laboratory, a star first has to die. The end of a star’s life depends largely on its mass. Unremarkable stars like the Sun go out with a ...

An international team of scientists have modelled formation and evolution of strongest magnetic fields in the Universe. An international team of scientists have modelled formation and evolution of ...

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 ...
