Astronomers used AI to search 35 years of Hubble data and discovered over 1,300 rare cosmic anomalies hidden in plain sight.

Astronomers have identified the most powerful and distant microwave laser, or maser, ever observed, originating from two ...

Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...

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 ...

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 ...

Scientists have long thought the Milky Way galaxy would someday collide with its closest neighbor, Andromeda. However, new research suggests the future of our cosmic home is more uncertain than ...

In my January 23, 2026, “The Universe” column, I wrote about some of the biggest bangs the universe has to offer: exploding stars, hiccupping magnetars, stellar disruptions and colliding black holes.

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 ...

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 ...
