Satellite GALEX charts history of star formation

Work by Professor Schiminovich, a leader in the development of the Galaxy Evolution Explorer (GALEX), a NASA ultraviolet space telescope, has shown how the production of stars in the universe has seen a rapid decline over the past 10 billion years. The solid line and hatched region chart this decline, moving from right to left toward the present day. Inset images show the GALEX satellite and ultraviolet image of the spectacular Pinwheel galaxy.
