HH 211: 形成中恒星的喷流
2023年9月19日 HH 211: Jets from a Forming Star Credit: NASA, ESA, CSA, Webb; Processing: Tom Ray (DIAS Dublin) Explanation: Do stars always create jets as they form? No one is sure. As a gas cloud gravitationally contracts, it forms a disk that can spin too fast to continue contracting into a protostar. Theorists hypothesize that this spin can be reduced by exp...
