Webb Telescope Probes Westerlund 1 Star Cluster
Astronomers using the James Webb Space Telescope have observed Westerlund 1, a supermassive star cluster in the Milky Way, revealing new insights into its structure and properties. The study, led by Mario Giuseppe Guarcello, utilized JWST's MIRI and NIRCam instruments to explore the cluster's members, protoplanetary disks, and the interaction between stars and their environment. The observations uncovered a diffuse nebulosity and elongated structures around massive stars, enhancing understanding of star formation and cluster dynamics.
