In a scientific first, astronomers have witnessed two objects violently colliding in space, the impact generating a dusty debris cloud reminiscent of cosmic fireworks. The collision occurred 25 ...
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 ...
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 ...

Mid-infrared observations from NASA's James Webb Space Telescope, shown in white, gray, and red, are combined here with X-ray data from NASA's Chandra X-ray Observatory, highlighted in blue. Together, ...
Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together. The razor-thin chain of galaxies sits inside a much larger filament that ...
Day 23 of the 2025 Space Telescope Advent Calendar: Distance and Perspective. This Hubble image features a trio of galaxies that appear to be very close together, but appearances can be deceiving. The ...
This mash-up of data from the James Webb Space Telescope and the Chandra X-ray Observatory reveals two galaxies mid-collision, with their spiral arms overlapping and bending toward their neighbors' ...
Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...
New data confirm that the titanic collisions of galaxies ignite the most powerful active galactic nuclei. Active galactic nuclei (AGN) are phases in which supermassive black holes at the centre of ...
Will the Milky Way and Andromeda galaxies collide in several billion years? The odds have changed with a new study using 100,000 supercomputer simulations. Credit: NASA's Goddard Space Flight Center ...
Thomas Anderson – otherwise known as Neo – is walking up a flight of stairs when he sees a black cat shake itself and walk past a doorway. Then the moment seems to replay before his eyes. Just a touch ...
