Pebbly Space Particles May Kick-start Formation Of Planets And Stars

Curiously large dust grains may contribute to development of bodies in space.   The Orion Nebula, courtesy of NASA Interstellar space can be a dusty place, filled with tiny flecks no bigger than a bacterial cell.But now astronomers have detected particles as big as pebbles, possibly a previously unknown type of dust that may kick-start the production of planets. The presence of these big particles may also suggest that star formation is more efficient than previously thought.Astronomers know th...
