This image made from a composite of September 2003 - January 2004 photos captured by the NASA/ESA Hubble Space Telescope shows nearly 10,000 galaxies in the deepest visible-light image of the cosmos, cutting across billions of light-years. In research released on Friday, April 26, 2019, Nobel winning astronomer Adam Riess calculates the cosmos is between 12.5 and 13.0 billion years old - about 1 billion years younger than previous estimates.
