Globular Cluster 47 Tucanae



One of the biggest brightest clusters of stars in the sky is 47 Tucanae, located in the southern constellation of the Toucan. Located about 16,000 light years away, this globular cluster contains a million times the mass of our Sun, and measures 120 light years across. The stars in the cluster are so dense, they average only 1/10th a light year apart; approximately the size of the Solar System. This photograph was taken using the European Southern Observatory’s Very Large Telescope
