“The close proximity of Stephan’s Quintet gives astronomers a ringside seat to galactic mergers and interactions
In an enormous new image, NASA’s James Webb Space Telescope reveals never-before-seen details of the galaxy group called “Stephan’s Quintet.” The close proximity of this group gives astronomers a ringside seat to galactic mergers and interactions. Rarely do scientists see in so much detail how interacting galaxies trigger star formation in each other, and how the gas in these galaxies is being disturbed. Stephan’s Quintet is a fantastic “laboratory” for studying these processes fundamental to all galaxies. The image also shows outflows driven by a supermassive black hole in one of the group’s galaxies in a level of detail never seen before. Tight galaxy groups like this may have been more common in the early universe when superheated, infalling material may have fueled very energetic black holes.”
