First Light

April 19, 2005
This is a collection of the details from the first image obtained by GALEX after launch. Traditionally called "First Light", the GALEX team dedicated this observation to the crew of the Shuttle Columbia who were lost over the skies of Texas on February 1st, 2003.

The observation is of a region in the constellation Hercules that was directly above Columbia when contact was lost with mission control. The pictures are constructed from images obtained with the Far ultraviolet (FUV) detector (colored blue) and Near ultraviolet (NUV) detector (colored red).

Although the exposure time for these images is much shorter then for GALEX survey observations, there are over 1500 sources detected in the NUV image and more then 400 in the FUV.
