Massive Star Cluster Discovered - Universe Today
This beautiful photograph taken by the Spitzer Space Telescope shows a region of space containing one of the largest clusters of stars ever seen. It appears to weigh in at 20,000 times the mass of our Sun, and contains at least 14 red supergiant stars. These supergiant stars are about as large as stars can get, and will die a violent supernova death within only a few million years. Spitzer used its infrared instrument to peer through the thick gas and dust that shrouds the centre of the Milky Way, obscuring them from view.
