Robert talks with Dr. Robert Williams, director of the Space Telescope Science Institute in Baltimore, about newly discovered information about galaxies. Based on preliminary data captured by the Hubble telescope, there are believed to be 5 times as many galaxies as we thought until now. Instead of 10 billion galaxies, the sample of the universe studied suggests there are more like 50 billion. Also, the galaxies closer to us are more distinct in shape. The older galaxies, 8 to 10 billion light years from earth, are amorphous in shape.
