Astronomer and Queen guitarist Brian May teams up with astrophysicist Derek Ward-Thompson to bring the cosmos to 3D.

In recent groundbreaking research published in Monthly Notices of the Royal Astronomical Society, scientists from the University of Queensland have provided insights into the likely fate of our galaxy ...

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 ...

The Andromeda Galaxy, the nearest major galaxy to the Milky Way, is slowly moving toward us at incredible speed. Astronomers ...

Some 1.2 billion light-years from Earth, a massive event is unfolding on cosmic scales. There, not two, but three galaxies are gradually coming together in a giant, triple collision named ...

In a patch of sky about 1.2 billion light-years from Earth, astronomers have found a cosmic rarity: three galaxies caught in a merger, and all three of their central supermassive black holes are ...

Two space telescopes really are better than one. This month NASA released a new image that combines observations from the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory of two ...

What does it look like when galaxies collide? The Hubble Telescope captured a unique sight as two galaxies are in the process of merging. NASA says the galaxy, called NGC 1614, is about 200 million ...

Most messages are press releases about astronomical discoveries—okay, scratch that; most of them are spam, but science announcements are an easy second place. But I also get questions from readers ...

Most of the (dark) matter beyond the Local Group of galaxies (which includes the Milky Way and the Andromeda Galaxy) must be ...

A new image from NASA's Hubble telescope shows spiral galaxy ESO 137-001 slamming through the Norma Cluster, spewing streams of gas in a fiery collision, and it's providing excellent fodder for ...
