NASA’s James Webb Space Telescope recently observed edge-on starburst galaxy Messier 82 (M82), nicknamed the Cigar Galaxy. Webb’s new view of M82, added to archival data from NASA’s Hubble Space Telescope, gives us a more complete picture of this starburst galaxy. Because Webb can see infrared light, it is able to peer through clouds of dust and gas to see the shape of this edge-on galaxy, as well as approximately 16.5 million of its stars.

M82’s rapid star formation, thought to be the result of its merger with another galaxy, will only be a (relatively) brief period in its history. Ironically, the extreme star formation is causing plumes of material to be ejected above and below the disk of the galaxy – something that will disrupt future stellar birth.
