Orion Nebula Rocks

www.sciencedaily.com/releases/2014/08/140827111809.htm August 27, 2014 Astronomers using the National Science Foundation's (NSF) Green Bank Telescope (GBT) 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. If confirmed, these dense ribbons of rocky material may well represent a new, mid-size class of interstellar particles that could help jump-start planet formation. "The large dust grains seen by the GBT would suggest that at least some protostars may arise in a more nurturing environment for planets," said Scott Schnee, an astronomer with the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia. "After all, if you want to build a house, it's best to start with bricks rather than gravel, and something similar can be said for planet formation." Music - Stale Mate by Jingle Punks
