One of our universe's biggest stars has dramatically turned into a rare, yellow 'hypergiant' star, and astronomers aren't sure when it will go supernova.

NASA’s James Webb Space Telescope captured the first published detection of a supernova progenitor in galaxy NGC 1637, ...

It's never too late to solve a cold case. A new paper from Syracuse University researchers proposes an explanation for both a mysterious stellar object discovered in the year 2013 and an astronomical ...

A strange flash in a distant galaxy first looked like a familiar kind of stellar wreckage, the radioactive afterglow of colliding neutron stars known as a kilonova. Then it brightened again, shifted ...

Astronomers say one of the universe’s largest stars has dramatically changed since 2014, possibly entering a rare final phase that could end in a spectacular supernova explosion.

A deep-space photo of the Jellyfish Nebula in Gemini shows a brain-like structure, capturing the supernova remnant IC 443 and surrounding interstellar gas and stars.

A distant stellar explosion has offered astronomers a rare natural experiment, one that turns gravity into a powerful optical tool. The object, known as SN 2025wny, appears not once but four times in ...

Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.

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