This Chandra image presents the first detection of X-rays from stars in the Quintuplet Cluster, an extremely dense young star cluster near the Galactic Center. Because dust blocks visible light from the Galactic Center, the cluster was not discovered until 1990 when it was detected with an infrared telescope. Named for its five brightest stars at infrared wavelengths, the Quintuplet is known to be home to hundreds of stars. Several of these are very massive stars that are rapidly losing gas from their surfaces in high-speed stellar winds.
