Galaxy Collisions Found to Activate Supermassive Black Holes, Euclid Data Shows

Astronomers using ESA’s Euclid telescope and AI analysis have found that merging galaxies are significantly more likely to host active supermassive black holes. The gravitational chaos of a collision drives gas toward the galactic core, igniting AGN activity. This discovery strengthens the link between galaxy interactions and the energetic processes that shape galac...

Chandra’s New X-Ray Mapping Exposes the Invisible Engines Powering Galaxy Clusters

NASA’s Chandra X-ray Observatory has released stunning colour-coded galaxy cluster images that reveal shock waves, cooling gas, and cavities carved by supermassive black holes. By separating X-ray light into different energy bands, astronomers can now visualise hidden cosmic processes that shape the universe’s largest structures and control how galaxies grow over ...
