Adding a new dimension to the early chemistry of the solar system

6 February 2016 Astronomy Now

An international research team has used sophisticated computer simulations to calculate a two-dimensional map of the dust chemistry in the solar nebula, the thin dusty disc that surrounded the young Sun and out of which the planets formed. The study has given new insights into the chemical composition of the dust grains that formed in the solar system 4.5 billion years ago.

Largest planets likely formed first from icy “planetary pebbles”

Researchers at Southwest Research Institute (SwRI) and Queen’s University in Canada have unravelled the mystery of how Jupiter and Saturn likely formed using computer simulations. The discovery, which changes our view of how all planets might have formed, also suggests that the gas giants in the solar system probably formed before the terrestrial planets.
