September 19, 2024. Stars in the extreme outer Milky Way. A cluster of bright points of blue and yellow light surrounded by a cloud of red gas. Astronomers are using NASA’s James Webb Space Telescope to study star formation in the far reaches of our Milky Way galaxy.
 
This colorful cluster of young stars is in the molecular cloud known as Diego Cloud 2.
 
Several of the young stars are emitting characteristic jets of material along their poles. Arrows point out explosive trails emanating from the cluster. The view shifts upward to another smaller cluster of bright blue, pink, and orange stars. Webb also confirmed a nearby sub-cluster of stars for the first time. Most chemical elements are created by stars, but this region does not have a lot of chemical variety, making it an intriguing place for astronomers to continue studying with Webb.
