SUMMARY: The newest image from the Hubble Space Telescope reveals one of the nearest globular star clusters, NGC 6397, located only 8,200 light years away in the constellation Ara. The stars in this cluster are packed one million times more densely than our own galactic neighborhood; collisions between stars occur every few million years. Two colliding stars may merge to become a "blue straggler"; a bright, young hot star that looks very different from the rest of the stars in the cluster.
