Hawaii astronomers estimate 300,000,000,000,000,000,000,000 stars
This photo provided by NASA, taken in 2006 by the 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. The bright part of the Hubble photo shows a cluster of galaxies 450 million light years with the giant elliptical galaxy ESO 325-G004 looming large at the cluster's center. (AP Photo/NASA)
