This image of Westerlund 2 released on March 19, 2026, features Chandra X-ray Observatory data (pink) and infrared data from NASA’S James Webb Space Telescope (red, orange, green, cyan, and blue). Scores of gleaming stars ringed in neon pink stretch across the frame, highlighting a cluster where stars are between one and three million years old. Brick-orange dust clouds along the bottom edge illustrate the raw materials of this active stellar nursery.

Westerlund 2 resides in a raucous stellar breeding ground known as Gum 29, located 20,000 light-years away from Earth in the constellation Carina.
