The James Webb Space Telescope has observed a surprising alignment in the spin directions of ancient galaxies, challenging ...

The Event Horizon Telescope captured the first image of the Milky Way galaxy's supermassive black hole Sagittarius A* — our galaxy's "black hole heart." Credit: ESO ...

Caltech’s Katie Bouman explains how the Event Horizon Telescope Collaboration captured the first imager of the Sagittarius A* ...

When any object gets close to a supermassive black hole, it's typically ensnared in a powerful gravitational pull. That's due to the event horizon – a theoretical boundary known as the "point of ...

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...

In 2019, the Event Horizon Telescope (EHT) Collaboration released the first image of a supermassive black hole at the center of the galaxy M87.

But what happens inside a black hole, beyond the event horizon from which nothing can escape, remains a mystery. In 1965, the British physicist Roger Penrose proved that under very general conditions, ...

In 2019, the Event Horizon Telescope Collaboration released the first image of a supermassive black hole at the center of the galaxy M87. In 2022, they presented an image of the black hole in our ...

"We would need to consider the possibility that the source was created (or trapped as a primordial black hole) by a highly advanced technological civilization," Harvard's Avi Loeb writes.

Black holes are invisible, yet they are among the brightest things in the universe. If a star wanders too close to a black hole, it gets torn apart in a fireworks show called a tidal disruption event.

The Big Bang is often described as the explosive birth of the universe - a singular moment when space, time and matter sprang into existence. But wha ...
