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 ...

DS1, collapsed into a black hole without exploding, revealing how stars die in silent “failed supernova” events.

Indian astronomer Kishalay De led study revealed one of the clearest cases of a massive star collapsing directly into a black hole without a supernova, based on NASA NEOWISE data.

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 are used to dramatic endings. When a massive star dies, it usually explodes ...

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 ...

The star used to be one of the brightest star in the neighboring Andromeda galaxy.

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

An international research team, including Kishalay De from the Massachusetts Institute of Technology (MIT), discovered ...

A stellar black hole is one that’s created from the gravitational collapse of particularly massive stars, typically greater than eight solar masses. For context, one solar mass is about equivalent to ...

Astronomers watching the Andromeda Galaxy have now seen something they had only theorized before: a massive star that simply vanished, apparently collapsing straight into a black hole instead of ...

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.
