An international team of astronomers has conducted photometric and spectroscopic observations of a recently discovered ...

One of the brightest stars in the Andromeda galaxy quietly collapsed into a black hole without any of the fanfare of a spectacular supernova. What makes this startling discovery even more remarkable ...

In A Nutshell A massive star in the Andromeda Galaxy faded by more than 10,000 times over a decade and vanished from view, likely collapsing into a black hole without exploding as a supernova ...

On April 10, 2024, the Asteroid Terrestrial-impact Last Alert System (ATLAS) detected first light from an explosion of a massive star with roughly 12 to 15 times the sun’s mass. Just 26 hours later, ...

For the very first time, astronomers have captured a radio signal emitted by a very specific type of stellar explosion. This unprecedented observation offers us a glimpse into the final moments of ...

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

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 ...

In 2014, a NASA telescope observed that the infrared light emitted by a massive star in the Andromeda galaxy gradually grew brighter. The star glowed more intensely with infrared light for around ...

Astronomers tracked a star that slowly faded instead of exploding. The quiet disappearance may reveal a hidden way black ...

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 ...

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...
