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

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 ...

One of the most spectacular encounters of Hubble with a galaxy has been brought back into focus by a recent image posted on X. The image, although pos.

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 ...

The universe is dynamic and constantly moving, and so are the galaxies enclosed in it. But what if two huge spiral galaxies draw closer, due to their gravity and pull everything around them into ...

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 ...

A breathtaking new space image has captured two spiral galaxies in the middle of a slow-motion cosmic collision, glowing in shades of blue, red, and silver. The picture shows galaxies NGC 2207 and IC ...

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 ...

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. This event was captured with ...

Astronomers have spotted an unexpected and dramatic event in the early universe: a tightly packed collision involving at ...

The pseudo-color images of JWST’s Quintet at redshift 6.71. a) The pseudocolor image created from NIRCam F115W (blue), F150W (green), and F200W (red) images. The five emission line galaxies in JWST’s ...
