Astronomers combined data from NASA’s JWST and Chandra X-ray Observatory to create a stunning new image of two merging spiral galaxies ...

Both NASA’s James Webb Space Telescope and Chandra X-ray Observatory caught these two galaxies in a close embrace.

Webb and Chandra reveal two spiral galaxies after an encounter, exposing heated gas, newborn stars and distorted arms, while hinting how the meeting will reshape them over billions of years.

NASA has released a new composite image of two spiral galaxies, NGC 2207 and IC 2163, as they begin a multi-billion-year process of merging into a single celestial entity.

Astronomers now believe the Milky Way's "inevitable" collision with a neighboring galaxy is much less likely than originally ...

It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported Monday that the probability of the two spiral galaxies colliding is ...
