Westerlund 1, the biggest and closest “super” star cluster to Earth, dazzles in this image released on July 23, 2025. This view combines x-ray data from NASA’s Chandra X-ray Observatory (in pink, blue, purple, and orange), infrared data from NASA’s James Webb Space Telescope (in yellow, gold, and blue), and optical data from NASA’s Hubble Space Telescope (in cyan, grey, and light yellow).
Data from Chandra and other telescopes is helping astronomers delve deeper into this galactic factory where stars are vigorously being produced. Observations from Chandra have uncovered thousands of individual stars pumping out X-ray emission into the cluster.
This image is part of a compilation of images featuring data from Chandra along with a host of other telescopes.

在2025年7月23日发布的这幅图像中，维斯特卢1熠熠生辉。它是距离地球最近、规模最大的“超级”星团。画面结合了多台望远镜的数据：NASA钱德拉X射线天文台的X射线数据（粉色、蓝色、紫色和橙色）、NASA詹姆斯·韦伯太空望远镜的红外数据（黄色、金色和蓝色），以及NASA哈勃太空望远镜的光学数据（青色、灰色和浅黄色）。
来自钱德拉和其他望远镜的数据正帮助天文学家深入探索这个银河工厂，这里正剧烈地孕育着恒星。钱德拉的观测揭示了数千颗恒星，它们不断向星团释放出X射线辐射。
这幅图像是由钱德拉和其他多台望远镜数据共同组成的合成影像集的一部分。
