In two separate studies, researchers identify nucleosynthetic isotope anomalies in the volatile elements potassium (K) and zinc (Zn) in meteorites, which constrain the origins of the material that ...

The Sun's formation caused temperature differences in the surrounding disk of gas and dust. Inner, hotter regions formed rocky planets from less volatile elements. Outer, colder regions allowed ...

Each December, meteors streak across the sky as part of the massive Geminid meteor shower, with up to about 120 meteors visible per hour at the shower’s peak. This reliable yearly show is a popular ...

Chemical analyses of meteorites allow for a better estimation of the chemical composition of the Earth and its potential building blocks. That is the result of a study conducted by a research team ...

Lunar rocks are famously dry. They contain almost none of the volatile elements that easily escape into space, such as ...

Volatile mystery The rocky planets Mercury, Venus, Earth and Mars. (Courtesy: NASA) Planetary scientists in France have reviewed and analysed recent research on the origins of “volatile” elements in ...

Our sun is a lifeless, fiery ball of gas fueled by a nuclear inferno. Earth, meanwhile, is a rocky, layered planet covered by water and teeming with life. Nevertheless, the elemental composition of ...
