The Sagittarius A* supermassive black hole at the core of the Milky Galaxy may be "warping the spacetime surrounding it into ...

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

New mathematical work provides a way to identify when information has been changed by manipulating space-time – and it may form a foundation for future space-time computers ...

For years, scientists have theorized that some black holes could actually be wormholes, and a new study shows that this space-time mimicry could in fact be possible.

It’s the largest black hole jet we’ve discovered to date. What makes this particular jet so exciting for astronomers is not only its size. It’s also estimated to be 1.2 billion years old.

Each jet emerges from an actively feeding supermassive black hole, known as a quasar, located about 11.6 billion and 11.7 billion light-years away.

For a long time the universe was assumed to be static, a potentially infinite pool of space that is neither expanding nor contracting. But during the 1920s, astronomer Edwin Hubble began measuring ...

Most galaxies around the size of the Milky Way or larger have a supermassive black hole skulking in their center. Each of these black holes can be millions or even billions of times more massive ...

The idea helped win Penrose a share of the 2020 Nobel prize in physics and inspired Hawking’s global bestseller A Brief History of Time: From the Big Bang to Black Holes. But there’s a caveat ...

Gaia, Europe’s Milky Way–mapping spacecraft, shut down earlier this year. It was arguably the most important—and most ...

Is the Hubble constant—a key part of how we measure the expansion of our universe—in a crisis? Some cosmologists say yes.
