韦布空间望远镜（JWST）向天文学家展示彗星的形成方式

天文学家长期以来一直困惑于太阳系彗星中岩石成分的来源。通过对韦布空间望远镜观测数据的分析，研究人员揭示了这些天体形成过程中的关键机制。

Astronomers have a problem. The comets in our solar system formed some 4.5 billion years ago in its frigid outer regions, beyond the current orbit of Jupiter. These “dirty snowballs” naturally contain lots of ices, but they also hold a surprising amount of rock. Key components of this rocky material are crystalline silicates such as Continue reading "JWST shows astronomers how to make a comet" The post JWST shows astronomers how to make a comet appeared first on Astronomy Magazine .
