Webb 望远镜观测恒星将热成形的晶体弹射到冷盘中,揭示行星如何形成。 Webb Telescope observes star ejecting heat-formed crystals into cold disk, revealing how planets may form.

James Webb空间望远镜已观测到晶体硅酸盐粒子——如石和恒星——正在从一颗年轻恒星的热内部区域EC 53被抛出,并被运到其圆盘的较冷的外部区域,那里形成彗星。 The James Webb Space Telescope has observed crystalline silicate particles—minerals like forsterite and enstatite—being ejected from the hot inner region of a young star, EC 53, and transported to colder outer regions of its disk, where comets form. 这些晶体每18个月定期爆发一次,在恒星附近形成,由强力风力和喷气式风力向外移动,对过去关于它们在寒冷环境中生存的假设提出了挑战。 These crystals, which form near the star during periodic outbursts every 18 months, are carried outward by powerful winds and jets, challenging past assumptions about their survival in cold environments. 这些结果发表在《自然》上,直接证明了早期行星系统中物质再分配的情况,有助于解释这些矿物在彗星中的存在,为包括我们自己在内的行星系统如何形成提供了新的见解。 The findings, published in Nature, provide direct evidence of material redistribution in early planetary systems and help explain the presence of such minerals in comets, offering new insight into how planetary systems, including our own, may have formed.
