Scientists at Lawrence Livermore National Laboratory recreated part of the intense chaos inside a nuclear fireball to better ...

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 ...

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 ...

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 ...

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 ...

The Lawrence Livermore National Laboratory study shows that the formation of radioactive fallout is more complex than some ...

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 ...

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 ...
