Hypothetical dark matter stars known as "boson stars" could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. In 2019, a ...

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 ...

Scientists watched as a star, once one of the brightest in the Andromeda galaxy, simply winked out of existence. They have a theory.

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.

A faint flash of infrared light in the Andromeda galaxy was emitted at the birth of a stellar-mass black hole – according to a team of astronomers in the US. Kishalay De at Columbia University and the ...

After looking for evidence of such an event for decades astronomers discovered they had the images but hadn’t noticed at the time.

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

NASA’s NEOWISE archival data tracks a massive star in Andromeda fading quietly into a black hole, providing detailed observations of stellar collapse and gas expulsion from 2005 to 2023.

Only one such event had been documented previously, a star recorded vanishing around 2010 in a galaxy 22 million light-years ...

Astronomers tracked a star in Andromeda as it dimmed and vanished without the usual fiery explosion, offering rare clues to ...

Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that ...
