UC Davis researchers have dated the earliest step in the formation of the solar system — when microscopic interstellar dust coalesced into mountain-sized chunks of rock — to 4,568 million years ago, ...

New work offers fresh evidence supporting the supernova shock wave theory of our solar system’s origin. According to one longstanding theory, our Solar System’s formation was triggered by a shock wave ...

A new planetary system is forming around the young star HOPS-315. Scientists observed the earliest stages of planet formation around another star. The process involves the cooling and solidifying of ...

Silicon monoxide gas detected by JWST signals the sublimation and recondensation of silicate dust into crystalline minerals. These minerals combine into pebbles, the earliest building blocks of ...
