This NASA image released on May 4, 2010 from the European Space Agency's Herschel Space Observatory shows the cloud associated with the Rosette Nebula, a stellar nursery about 5,000 light-years from Earth. The formation of new stars in galaxies like the Milky Way has declined five-fold in the last three billion years, initial findings of the European Space Agency's Herschel telescope showed.
