New data from NASA’s James Webb Space Telescope shows where crystalline silicates form around young stars and how disk outflows transport them to colder, outer regions.

The presence of crystalline silicates in comets has been a long-standing conundrum. These minerals need intense heat to form, ...

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 ...

For the first time, a high-pressure calcium silicate perovskite (CaSiO 3) has been identified as a naturally occurring mineral from Earth’s lower mantle, researchers report. The newly discovered ...

Asteroid Bennu—the target of NASA's OSIRIS-REx sample return mission, led by the University of Arizona—is a mixture of materials from throughout, and even beyond, our solar system. Over the past few ...
