This image of the spiral galaxy Messier 83 (M83) was taken during only 1 orbit of GALEX on June 7th 2003. This picture is a combination of GALEX images taken with the FUV (colored blue) and NUV detectors (colored red).
M83 displays significant amounts of ultraviolet emission far from the optically bright portions of the galaxy. It is also known to have an extended Hydrogen disk that GALEX detects in faint ultraviolet light.
The red stars in this image are foreground stars in our own Milky Way galaxy.
