Webb Maps 16.5 Million Stars in the Cigar Galaxy, Tracing Its Starburst History
NASA's James Webb Space Telescope revealed about 16.5 million individual stars in edge-on Messier 82 (the Cigar Galaxy) by peering through dust, mapping its distended disk and a rapid, merger-driven starburst. The Webb data, complemented by Hubble observations, help researchers probe how star formation and outflows have shaped M82 over the past few hundred million years.
