TL;DR

NASA's James Webb Space Telescope spent 65 hours capturing a 223-megapixel, near-infrared image of Messier 82 (the Cigar Galaxy), resolving about 16.5 million stars and revealing a distended disk; when combined with Hubble data, the image helps scientists study M82's unusually rapid star formation (around 10 times faster than the Milky Way) and its evolutionary history.
