This artist's illustration shows a stage in the predicted merger between our Milky Way galaxy and the neighboring Andromeda galaxy, as it will unfold over the next several billion years. In this image ...

What happens when two rare ring galaxies collide? They form an infinity symbol—or the face of a cosmic owl, depending on how you look at it. The James Webb Space Telescope has helped two international ...

A 50-million-light-year-long flow of hydrogen gas has been observed linking two tiny galaxies 50 million light-years away, giving astronomers a spectacular view of how galaxies attract, warp, and ...

Here's some good news: Our galaxy may not be destined to end in a fiery collision with the Andromeda galaxy as soon as previously thought. While earlier research regarded the collision as a virtual ...

Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum plaguing the standard model of cosmology. New observations of a pair of ...

Our galaxy may not collide with its neighbor after all, suggests new research. For over a century, astronomers believed a dramatic collision between the Milky Way and Andromeda galaxies was inevitable ...

According to the prevailing “cold dark matter” theory of the evolution of the universe, every galaxy is surrounded by a halo of dark matter that can only be detected indirectly by observing its ...
