In 1877, Edouard Stephan discovered a tight visual grouping of five galaxies located in the constellation Pegasus. The galaxies of Stephan's Quintet are both overlapping and interacting, and have become the most famous among the compact groups of galaxies. Astronomers have long known that four of the galaxies (all of which are yellowish-white in this video) form a physical group in space, while the fifth (bluish) is a foreground galaxy. In addition, a sixth galaxy (yellowish-white and on the far

In this Quintet, four galaxies move around each other, held together by gravity, while a fifth galaxy sits in the frame a further distance away. This sonification was created using images from NASA's James Webb Space Telescope with additional data from the Spitzer Space Telescope and X-ray light from the Chandra X-ray Observatory. | NASA's Marshall Space Flight Center | Facebook
