The KM3NeT collaboration is a large research group involved in the operation of a neutrino telescope network in the deep ...

Scientists scanning the heart of the Milky Way have spotted a tantalizing signal: a possible ultra-fast pulsar spinning every 8.19 milliseconds near Sagittarius A*, the supermassive black hole at our ...

The event was first recorded in 2014, when a Nasa space telescope noticed a massive star in the Andromeda galaxy slowly becoming brighter in infrared light.

Their research was guided by a prediction from the 1970s: if a star collapses directly into a black hole, it should briefly ...

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 ...

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 my January 23, 2026, “The Universe” column, I wrote about some of the biggest bangs the universe has to offer: exploding stars, hiccupping magnetars, stellar disruptions and colliding black holes.

Astronomers have captured one of the clearest views ever of a massive star dying—not in a dramatic supernova explosion, but ...

A massive star in the nearby Andromeda galaxy has simply disappeared. Some astronomers believe that it's collapsed in on ...

The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s ...

A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen ...

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 object with gravity so strong not ...
