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 ...

A study into the zinc isotope composition of meteorites by researchers from the University of St Andrews suggests that material from the outer solar system was an important source of volatile elements ...

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 ...

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 ...

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 ...

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 ...

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 ...
