Webb finds young sun-like star forging common crystals and flinging them into its outer disk
Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, since crystals require intense heat to form and these “dirty snowballs” spend most of their time in the ultracold Kuiper Belt and Oort Cloud. Now, looking outside our solar system, NASA’s James Webb Space Telescope has returned the first conclusive evidence that links how those conditions are possible.
