Astronomers have captured the clearest-ever close-up images of two exploding stars, events known as novae, within days of their eruption. These detailed images show that such explosions are far more ...

Dark matter, if it exists, is probably in the latter category. If hypothetical weakly interacting massive particles (WIMPs) are real, their collisions with regular matter may have left fossil traces ...

Scientists have for the first time peered inside a dying star as it exploded in a supernova, gaining not just unprecedented views of its layers, but more so, insight into the process of stellar ...

One of the largest known stars in the cosmos is poised for catastrophe. After witnessing the massive object undergo a dramatic transformation, a team of astronomers say the star is on the verge of ...

How can artificial intelligence (AI) help astronomers identify celestial objects in the night sky? This is what a recent study published in Nature Astronomy hopes to address as an international team ...

THE cosmic rays that crash into telescopes are normally just a nuisance for astronomers, but they may bring an unexpected benefit: they could be used to generate truly random numbers. Exploding stars ...

Nearly 4.5 million years ago, two enormous, blazing stars swung close to the solar system. They did not touch the sun, but they came close enough to leave a permanent mark on the thin mist of gas that ...
