NASA has detected a precursor or progenitor to a supernova for the first time – and it's all thanks to old photos. Researchers have now been able to study some of a supernova's progression by ...

"We can study a diverse population of supermassive black holes and their radio jets at different stages of their evolution." ...

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 ...

This one red giant star has been making it to Google news a few times a year because some scientist or the other says it is about to explode. Well, this star has been on the verge of exploding for ...

One of the largest stars close enough for us to estimate its size, WOH G64, appears to have gone from red to yellow in 2013-14, indicating a temperature rise of about 1,000°C (1,800°F). Last year it ...

A massive star brightened in infrared light, then vanished without exploding. Astronomers uncovered the quiet birth of a black hole.

Astronomers watched a massive star in the Andromeda Galaxy vanish over a decade, providing rare evidence of a "failed ...

Their research was guided by a prediction from the 1970s: if a star collapses directly into a black hole, it should briefly glow in infrared light as it sheds its outer layers and becomes wrapped in ...

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 mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...
