In a groundbreaking study, NASA's Chandra X-ray Observatory has revealed new insights into Westerlund 1, the largest and closest 'super' star cluster to Earth. Led by astronomers from the Italian National Institute of Astrophysics in Palermo, the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project marks a significant milestone in understanding this cosmic phenomenon. Chandra's observations, combined with data from other NASA telescopes, show a vibrant star cluster with active star formation and a halo of hot gas surrounding its core.
