Asteroid Ryugu and some carbonaceous meteorites, which are thought to have similar origins in the early solar system, are known as chemically "primitive" materials because they preserve the chemical ...

Researchers from Penn's Department of Physics and Astronomy have developed a new method for better understanding the relationship between a star's chemical composition and planet formation. The study ...

A new study published in Atmospheric Environment by researchers at the University of North Carolina at Chapel Hill has analyzed space and time trends for fine particulate matter (PM2.5) in the ...

The chemical composition of a planetary body reflects its starting conditions modified by numerous processes during its formation and geological evolution. Measurements by X-ray, gamma-ray, and ...

Glass is an amorphous material, which means that the structure of glass lies between that of a crystalline material and a liquid. Glass is often considered as a super-cooled liquid. At high ...
