James Webb Space Telescope Peers Deep Into the Heart of Star Formation in Our Milky Way Galaxy
Webb’s infrared instruments revealed dense clouds and massive young stars in Sagittarius B2, the Milky Way’s largest star-forming region, with unprecedented clarity.
- On September 25, 2025, NASA's James Webb Space Telescope captured vibrant images showcasing bright stars and luminous interstellar dust within the Sagittarius B2 molecular cloud, one of the Milky Way's most active regions of star formation.
- Sagittarius B2, although containing just about 10% of the star-forming gas in the Milky Way’s galactic center, is responsible for producing half of the stars there, making it the most prolific star-forming cloud near the supermassive black hole Sagittarius A*.
- Webb’s near- and mid-infrared instruments captured stunning details of the region’s stars and glowing cosmic dust; however, some areas appear dark because they are filled with thick clouds of gas and dust that block Webb’s view.
- Graduate student Nazar Budaiev expressed that while the Webb telescope reveals many fresh insights, it simultaneously opens up additional questions to investigate, making it thrilling to contribute to this continuous exploration of star masses and ages.
- Researchers anticipate that analysis of Webb’s observations will shed light on longstanding questions about massive star formation and clarify why Sagittarius B2 exhibits much greater activity compared to other regions in the galactic center.
