You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome ...

The James Webb Space Telescope has peered through cosmic dust to reveal new details and a stunning image of a rare type of galaxy. The space observatory's latest image shows the Cartwheel galaxy, a ...

NASA’s James Webb Space Telescope (JWST) has captured images of a distant galaxy that is forming a peculiar cosmic structure ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Last month when scientists announced new ...

Examples of merging galaxies containing a heavily obscured growing supermassive black hole observed by the Hubble Space Telescope. The top panels show nearby galaxies at ~500 million light-years from ...

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 ...

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 ...

In a remarkable breakthrough, astronomers have uncovered the first known triple system where three galaxies, each harboring an active, radio-bright supermassive black hole, are caught in the midst of ...

Astronomers have long known that the Andromeda galaxy, aka Messier 31, a swirling city-state of a trillion stars — plus all the accouterments of gas, dust, dark matter and black holes — is rumbling ...

Using early data from the European Space Agency’s Euclid space telescope, astronomers have analyzed over one million galaxies to test a long-standing idea in astrophysics: that galaxy mergers help ...
