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

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 ...

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 ...

The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s that theorized that when a star underwent direct collapse, it would leave ...

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 ...

Several telescopes used to observe the supernova SN Zwicky which was magnified nearly 25 times by a foreground galaxy acting ...

WASHINGTON, Feb 12 (Reuters) - The formation of a black hole can be quite a violent event, with a massive dying star blowing up and some of its remnants collapsing to form an exceptionally dense ...

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 ...

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 ...
