Gum 25

March 31, 2003
Atlas Image mosaic, covering 15´ × 15´ on the sky of Gum 25, aka RCW 40. This is a bright southern HII, or ionized hydrogen, region, with a cluster of hot, young, massive stars that are providing the ionizing ultraviolet photons. The nebula is clearly dusty, as can be seen in the 2MASS image. 2001 Sep 4-25
