A new image from NASA’s Webb Telescope captures a stunning new look at M90, a massive spiral galaxy escaping the Virgo Cluster and heading toward the Milky Way, Earth’s home galaxy.

Astronomers have identified dozens of stellar streams in the Milky Way, offering clues about the galaxy’s structure and hidden dark matter.

A team of astronomers has reconstructed the 12-billion-year evolutionary history of a giant spiral galaxy, marking a major step toward understanding how galaxies like our own Milky Way formed. The ...

It’s constant, invisible, and far more powerful than it seems. You’re part of it, but most people never notice.

The oxygen in a galaxy does not sit still. It spreads, thins out, piles up, and leaves behind a record of where stars formed, where gas moved, and when smaller galaxies crashed in. In the nearby ...

For the first time, scientists have reconstructed the full history of a galaxy outside the Milky Way using chemical clues. By analyzing oxygen across NGC 1365 and comparing it with simulations, they ...
