Young sunlike system reveals comets may carry water toward forming planets
📌 概要
瑞典隆德大学天文学家在一颗类似太阳的年轻恒星周围发现系外彗星存在的证据。观测表明，彗星可能将水从行星系统寒冷的外围区域运送到行星形成区，为揭示地球等行星上水的来源提供了新线索。
⚡ 关键要点
- ▸瑞典隆德大学在一颗类太阳年轻恒星周围探测到系外彗星
- ▸彗星可能是将水从系统外缘输送至行星形成区的机制
- ▸该发现有助于理解行星系统及地球水的起源
Astronomers at Lund University in Sweden have found evidence of exocomets—comets in other solar systems—orbiting a young star similar to our sun. The observations point to a possible mechanism for how water might be transported from the cold outer regions of the planetary system to regions where planets form.
