NGC 604: Giant Stellar Nursery
Explanation: Scattered within this cavernous nebula , cataloged as NGC 604 , are over 200 newly formed hot, massive, stars. At 1,500 light-years across, this expansive cloud of interstellar gas and dust is effectively a giant stellar nursery located some three million light-years distant in the spiral galaxy, M33 . The newborn stars irradiate the gas with energetic ultraviolet light stripping electrons from atoms and producing a characteristic nebular glow . The details of the nebula's structure hold clues to the mysteries of star formation and galaxy evolution.
