Big planets get a head start in pancake-thin nurseries

Super-thin planet nurseries have a boosted chance of forming big planets, according to a study announced this week at the Europlanet Science Congress (EPSC) 2022 in Granada, Spain. An international team, led by Dr. Marion Villenave of NASA Jet Propulsion Laboratory (JPL), observed a remarkably thin disk of dust and gas around a young star, and found that its structure accelerated the process of grains clumping together to form planets.
