One of the largest known stars in the cosmos is poised for catastrophe. After witnessing the massive object undergo a ...

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, ...

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.

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

It was only last October that telescopes spotted a gamma ray burst—caused by the collapse of a black hole —that was so powerful astronomers quickly dubbed it BOAT, for “Brightest of all Time.” That ...

Few spectacles in space are as phenomenal as supernovae, but a "superkilonova" may give them a run for their money. This type of cosmic outburst is thought to arise when a supernova cascades into a ...

What we know of the birth of a black hole has traditionally aligned with our perception of black holes themselves: dark, mysterious, and eerily quiet, despite their mass and influence. Stellar-mass ...

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 ...

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