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 ...

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 ...

Volatile elements, such as carbon, hydrogen, nitrogen and sulfur (S), are of profound importance for the formation, the differentiation and the habitability of a planet. However, today's Earth, though ...

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 severely depleted in moderately volatile elements such as Rb, K, and Zn relative to Earth. Identifying the cause of this depletion is important for understanding how the Earth-Moon ...

They found that around half the Earth's inventory of the volatile element zinc came from asteroids originating in the outer Solar System -- the part beyond the asteroid belt that includes the planets ...

Earth’s surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

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 ...

Geologists gain new insights regarding the Earth's composition by analyzing meteorites. They conclude that the building blocks that brought volatile elements to Earth have a chemical composition ...
