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 ...

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 ...

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

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 ...

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 ...
