Webb Telescope observes star ejecting heat-formed crystals into cold disk, revealing how planets may form.
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.
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.
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.
