<p>This photo taken in 2006 by Hubble Space Telescope shows a cluster of diverse galaxies. A new study led by a Yale University astronomer looks at elliptical galaxies, such as the bright one in the top middle of this 2006 Hubble Space Telescope photograph, and finds they have far more stars than initially thought. That means the universe may have three times more stars than astronomers previously figured.</p>
