Scientists still don’t quite understand how gas giants form. But Hiroshi Kobayashi of Nagoya University and Hidekazu Tanaka of Tohoku University have made computer simulations that have brought new understanding. Here’s more from Phys.Org:
“We already know quite a bit about how planets are made,” says Kobayashi. “Dust lying within the far-reaching ‘protoplanetary disks’ surrounding newly formed stars collides and coagulates to make celestial bodies called planetesimals. These then amass together to form planets. Despite everything we know, the formation of gas giants, like Jupiter and Saturn, has long baffled scientists.”
