| Early growth of giant galaxy, just 3 billion years after the Big Bang, revealed Posted: 27 Aug 2014 10:15 AM PDT The birth of massive galaxies, according to galaxy formation theories, begins with the buildup of a dense, compact core that is ablaze with the glow of millions of newly formed stars. Evidence of this early construction phase, however, has eluded astronomers — until now. Astronomers identified a dense galactic core, dubbed "Sparky," using a combination of data from several space telescopes. Hubble photographed the emerging galaxy as it looked 11 billion years ago, just 3 billion years after the birth of our universe in the big bang. |

To make this observation, the team also enlisted the help of a gravitational lens, a galaxy-size magnifying glass, to reveal otherwise invisible detail. |
