Meteorites lend clues to origins of earliest history of solar system

Lawrence Livermore National Laboratory (LLNL) scientists and a collaborator from the University of Münster reviewed recent work that shows how meteorites exhibit a fundamental isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC – rocks or sediments containing carbon or its compounds) groups, which most likely represent material from the inner and outer solar system.

How Planets May Form After Dust Sticks Together

Scientists may have figured out how dust particles can stick together to form planets, according to a Rutgers co-authored study that may also help to improve industrial processes. In homes, adhesion on contact can cause fine particles to form dust bunnies. Similarly in outer space, adhesion causes dust particles to stick together. Large particles, however, can combine due to gravity – an essential process in forming asteroids and planets. But between these two extremes, how aggregates grow has largely been a mystery until now.
