Deep below the earth's surface lies a thick, rocky layer called the mantle, which makes up the majority of our planet's volume. For decades, scientists have known that most of the lower mantle is a ...

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 ...

It’s common for researchers to conduct a mineral analysis on a suspected meteorite, dissecting and identifying its compounds to determine what it is and where it came from. The process is usually done ...

Earth's most abundant mineral lies deep in the planet's interior, sealed off from human eyes. Now, scientists for the first time have gotten a glimpse of the material in nature, enclosed inside a ...

What are asteroids made of? Asteroids are made mostly of rock—with some composed of clay and silicate—and different metals, mostly nickel and iron. But other materials have been found in asteroids, as ...

An important aspect of Raman effect is that it is extremely sensitive to even small amount of differences in chemical structures. Even if all vibrations are not observed with Raman spectroscopy, ...

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 ...
