30 Doradus star clusters. Hubble Space Telescope (HST) image of star clusters (blue) in the Tarantula Nebula (30 Doradus,NGC 2070). What was thought to be a single cluster was found to be two clusters merging. The clusters differ in age by about a million years. Hot massive stars are blue,oxygen glows green,and fluorescing hydrogen is red. 30 Doradus is 170,000 light years from Earth,in the constellation of Dorado. Image data obtained 20-27 October 2009 by Hubble's Wide Field Camera 3 (WFC3) and its UVIS (ultraviolet and visible) sensor | |
