Stephan’s Quintet - MIRI Camera
Webb's Mid-InfraRed Instrument (MIRI) revealed never-before-seen details of Stephan’s Quintet, a grouping of five galaxies. MIRI's infrared capabilities pierced through dust to uncover shock waves, tidal tails, and hidden star-forming regions. The various colors represent differing features: red marks dusty, star-forming regions and extremely distant, early galaxies; blue shows stars or star clusters without dust; and green and yellow indicate distant background galaxies rich in hydrocarbons. Stephan’s Quintet is also known as Hickson Compact Group 92 (HCG 92). Despite the name, only four of the galaxies are interacting, while the fifth is much closer to Earth. The top galaxy, NGC 7319, contains a supermassive black hole 24 million times the mass of the Sun, actively accreting material and radiating the energy of 40 billion Suns. MIRI’s deep sensitivity also revealed numerous background galaxies, offering a glimpse into the universe’s distant past and providing astronomers a rare view
