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 ...

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 ...

Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...

It’s much sooner than you think.

One of the brightest stars in the Andromeda galaxy has disappeared without the explosion astronomers expected. Instead, they ...

Physicists suggest that a single, extraordinarily powerful cosmic signal detected on Earth could be linked to the explosive end of a tiny black hole from the early universe. That signal now stands as ...

"Imagine if the star Betelgeuse suddenly disappeared. Everybody would lose their minds!" The post Scientists Intrigued as ...

In a groundbreaking study published in PRX Quantum, researchers led by Enrico Rinaldi have used quantum computing and AI to simulate the quantum structure hidden inside black holes. For the first time ...

Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's ...

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...
