Abell 2744 Y1 is a galaxy in the cluster of galaxies Abell 2744 13 billion light-years from us in the constellation Sculptor . It has a diameter of 2,300 light years, 50 times smaller than the Milky Way , but produces 10 times more stars [4] . The galaxy was discovered in July 2014 by an international team led by astronomers from the Canary Institute of Astrophysics (IAC) and La Laguna University (ULL) [5] as part of the Frontier Fields program using NASA's Spitzer and Hubble space telescopes.
