The Galaxy
Evolution Explorer (GALEX) is a NASA Small
Explorer mission that was launched in April 2003 and is continuing to
conduct
nested surveys and targeted observations of the space ultraviolet sky. A principal goal of the GALEX mission is to
study the history of star formation in the universe and determine the
physical
drivers for this evolution. In this talk
I will present some of the key science results from GALEX after nearly
five
years in orbit and also highlight several new discoveries of energetic
transient and dynamic phenomena.
