A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

A massive star roughly 2.5 million light-years away in the Andromeda Galaxy has quietly disappeared, and the best explanation is that it collapsed directly into a black hole without producing a ...

A bright star in the Andromeda galaxy appears to have simply vanished. After a dramatic mid-infrared flare in 2014, the object has faded in visible light by a factor of more than 10,000 by 2023, ...

Vagins is an experimental physicist, but his work relies on a vast complex machine underpinned by an orchestra of subsystems – mechanical, electronic, computational and human – each playing precisely ...

A Northwestern University-led team of astronomers used NASA’s James Webb Space Telescope to discover a former star that ...

NASA has detected a precursor or progenitor to a supernova for the first time – and it's all thanks to old photos.

That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion ...

Researchers used James Webb Telescope images to identify the star, which went supernova 40 million years ago ...

One of the largest known stars in the universe underwent a dramatic transformation in 2014, new research shows, and may be preparing to explode. A study led by Gonzalo Muñoz-Sanchez at the National ...

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.

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