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 ...

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 ...

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 ...

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 ...

Washington, D.C.–Tiny variations in the isotopic composition of silver in meteorites and Earth rocks are helping scientists put together a timetable of how our planet was assembled beginning 4.568 ...

Earth's surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H 2 O), nitrogen (in atmospheric N 2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

It appears that nature has a fondness for forming exoplanets – planets beyond our own Solar System. Over the last 20 years, scientists have realised that exoplanets are far more common in our corner ...
