About 400,000 years after the Big Bang, the cosmos was a very dark place. The glow of the universe's explosive birth had cooled, and space was filled with dense gas —mostly hydrogen—with no sources of light.

Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.
When spectacular cosmic events such as galaxy collisions occur, it sets off a reaction to form new stars, and possibly new planets that otherwise would not have formed. The gravitational pull that forces the collisions between ...

Within almost every galaxy there is a supermassive black hole. This by itself implies some kind of formative connection between the two. We have also observed how gas and dust within a galaxy can drive the growth of galactic ...

Within almost every galaxy is a supermassive black hole. Millions, sometimes billions of solar masses are locked within an event horizon of space and time. They can power luminous quasars, drive star formation, and change ...

There's an incredibly ancient black hole out there that's challenging astronomers to explain how it could exist only 400 million years after the Big Bang. It's at the heart of a galaxy called GN-z11. Astronomers using JWST ...
