In a recent breakthrough, astronomers have utilized NASA’s James Webb Space Telescope (JWST) to survey the starburst galaxy Messier 82 (M82), located approximately 12 million light-years away in the constellation Ursa Major. This compact yet frenetic galaxy has been forming stars at a rate ten times greater than our Milky Way, earning it the nickname ‘Cigar Galaxy’. Webb’s ability to observe in the infrared spectrum proved crucial in navigating the murky conditions surrounding star formation.
Surveying M82 with Webb
Astronomers have been studying M82 for decades, captivated by its intense star formation and unique features. The JWST’s advanced capabilities allowed them to delve deeper into the galaxy’s dynamics and uncover new insights.
Navigating the Infrared Spectrum
The intense star formation in M82 is accompanied by thick clouds of dust, which obscure observations in visible light. By observing in the infrared, Webb was able to peer through these obscuring clouds and capture a clearer view of the processes at work. This infrared vision proved essential for understanding the complex mechanisms driving the galaxy’s prolific star birth.
