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 ...

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 ...

If a massive star near Earth exploded into a supernova, the result wouldn’t just be beautiful — it would be catastrophic.

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 ...

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

Somewhere in the night sky, a massive star is nearing the end of its life. Astronomers believe it could erupt into a ...

What can an exploding star in a distant galaxy teach scientists about red supergiants? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of ...

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 ...

NASA's Chandra X-ray Observatory and Hubble Space Telescope confirmed the existence of a companion star orbiting Betelgeuse, ...
