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 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 ...

When the two stars eventually smash into each other, the supernova explosion would be visible from Earth, even during daytime.

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

Betelgeuse, 650 light years away, may be nearing the end of its fuel, meaning its supernova could light Earth’s skies as bright as the full moon.

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 ...

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

The first double-burst supernova ever observed, SNR 0509, is a historic discovery that reveals how white dwarfs explode in ...

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 ...

In November 1572, a brilliant new star appeared in the constellation Cassiopeia, shining so brightly that it was visible during the day. Danish astronomer Tycho Brahe carefully documented this ...
