Astronomers Have Identified Some of Universe's Oldest Galaxies A team from the Institute for Computational Cosmology at Durham University and the
Harvard-Smithsonian Center for Astrophysics
has made an interesting discovery. They have found evidence that the faint satellite galaxies surrounding the Milky Way are some of the first galaxies ever formed in our Universe. The findings suggest that the galaxies, including Segue-1, Bootes I, Tucana II and Ursa Major I, are over 13 billion years old. Professor Carlos Frenk, via Phys.org The team had made a theoretical model of galaxy formations which ended up perfectly coinciding with the actual data, which allowed them to infer the formation times of the satellite galaxies. Dr. Sownak Bose, via Phys.org The team's findings are published in the Astrophysical Journal.
