Astronomers were puzzled by a black hole around 50 million times the mass of the sun with no stars, spotted by the James Webb ...

A strange X-ray beacon from deep space has revived a decades-old mystery and opened a window onto one of the universe’s most violent possibilities. Astronomers now suspect that this flicker in the ...

Astronomers have detected the signal of a colossal black hole in deep space that likely formed when two already-large black holes crashed into each other billions of light-years away. The result is a ...

Over the past decade, the LIGO-Virgo-KAGRA (LVK) network has detected hundreds of black hole mergers, but none quiet as large as GW231123. At 225 solar masses, the black hole resulting from the merger ...

The Great Blue Hole off the coast of Belize looks like someone punched a perfect circular hole straight through the ocean floor, creating a dark blue void that’s so massive and distinct it shows up ...

"The James Webb Space Telescope has opened a new frontier in extragalactic astrophysics, revealing objects we didn't even suspect existed, and we're only at the beginning of this adventure." When you ...

What would a human see and feel while falling into a black hole? In this exclusive excerpt of his new book, "Facing Infinity," author and astrophysicist Jonas Enander tells us in terrifying detail.

Primordial black holes are hypothetical black holes thought to have formed moments after the Big Bang. Because they supposedly formed about 14 billion years ago, and black holes are thought to ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Two black holes merged together 2.4 billion light years away from Earth, and scientists have just figured out how fast the newborn ricocheted, and in which direction. When you purchase through links ...

This engine won't be fueling interstellar missions, but still finds an unexpected way to use deep space energy to generate power. Reading time 3 minutes Deep space may provide hidden sources of energy ...
