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.

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 ...

Using NASA’s James Webb Space Telescope, astronomers from Seoul National University and other international institutions have ...

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 ...

"The process acts as a multiplier," Kanan said. "You take one reactive mineral, calcium oxide, and a magnesium silicate that is more or less inert, and you generate two reactive minerals." As a quick ...

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