Planet formation starts with the coagulation of dust grains from small interstellar dust to pebbles. Dust grains in the ISM are formed at the end stages of stellar life. However, they can also be formed via a condensation process in the inner regions of planet-forming disks. Toward the protostellar system HOPS-315, JWST sees both gas- and solid-phases of building blocks of planets. In particular, the detection of the rovibrational SiO gas emission toward the inner region of the young disk strongly indicates an ongoing condensation process that signifies the earliest stages of planet formation. The same process occurred in the young solar system.
