| 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. |
| Orion rocks! Pebble-size particles may jump-start planet formation Posted: 27 Aug 2014 08:18 AM PDT Astronomers have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles -- planetary building blocks 100 to 1,000 times larger than the dust grains typically found around protostars. |
