Ultraviolet and Visible images of NGC 300

April 15, 2005
The image on the right shows a comparison of the GALEX image of NGC 300 taken in ultraviolet light with an image in visible light (that human eyes can see) from the Digitized Sky Survey.

NGC 300 is often used as a prototype of a spiral galaxy because in visible images it displays flowing spiral arms and a bright central region of older (and thus redder) stars. The GALEX image taken in ultraviolet light shows us that NGC 300 is an efficient star forming galaxy. The bright blue regions in the GALEX image reveal new stars forming all the way into the nucleus of NGC 300.
