James Webb Telescope Finds Carbon-Rich Planet Nursery

The discovery challenges long-standing assumptions about the chemistry of planetary birthplaces.

Artist’s illustration of the aftermath of the first-of-its-kind supernova SN 2021yfj. Well before the explosion, the progenitor star had lost its outer layers, consisting only of its oxygen and silicon core – a star for which no analogue exists in the Milky Way. Yet, this stripped-to-the-bone star underwent further intense mass-loss episodes, ejecting shells of material rich in silicon (grey), sulphur (yellow), and argon (purple). The violent collision of these massive shells produced a brilliant supernova, visible even from 2 billion light-years away. This supernova is so unusual that it defines a new class, Type Ien
