Using powerful instruments at the Keck Observatory in Hawaii, astronomers recently discovered that the universe stretched much further than originally thought. Between 50 and 300 million light years away, feint light from red dwarf stars in eight giant "elliptical galaxies" suggest there may be three times the number of stars originally thought to exist in the universe. Joining us is Brendan Owens, an astronomer at the Royal Observatory in Greenwich, England.
