A bright star cluster glitters like a fireworks display over a cloud of interstellar gas and dust in a Hubble Space Telescope picture released July 6.
The young cluster, dubbed NGC 3603, is filled with stars that were born around the same time but have grown up to have different sizes and masses. Because more massive stars die sooner than less massive ones, the cluster acts like a cosmic petri dish, in which astronomers can study the various stages of stars' life cycles.
