SOACE-SPITZER M81 GALAXY
In a new ultraviolet image released by NASA 05 May, 2007, the magnificent M81 spiral galaxy is shown at the center. The orbiting observatory spies the galaxy's "sizzling young starlets" as wisps of bluish-white swirling around a central golden glow. The tints of gold at M81's center come from a "senior citizen" population of smoldering stars. The image is one of thousands gathered so far by GALEX, which launched April 28, 2003. This mission uses ultraviolet wavelengths to measure the history of star formation 80 percent of the way back to the Big Bang. M81 and Holberg IX are located approximately 12 million light-years away in the northern constellation Ursa Major. AFP PHOTO/HO/NASA/JPL-Caltech/Harvard-Smithsonian CfA
