This image from NASA's Galaxy Evolution Explorer shows the galaxy NGC 300, located about seven million light-years away in the constellation Sculptor. It is a classic spiral galaxy with open arms and vigorous star formation throughout.
Blue represents ultraviolet light captured by the telescope's long-wavelength detector. Green shows ultraviolet light from the short-wavelength detector, and red shows red visible light from the Las Campanas Observatory, Chile.
The Galaxy Evolution Explorer data was taken in October 2003.
