For many years, scientists have predicted that many of the elements that are crucial ingredients for life, like sulfur and nitrogen, first came to Earth when asteroid-type objects carrying them ...

A study published in Science Advances demonstrates, through experiments conducted at very high pressure and high temperature at the Institute of Earth Physics of Paris (IPGP), that volatile ...

Earliest inner solar system planetesimals shaped the inventory of moderately volatile elements in terrestrial planets. Understanding where Earth's essential elements came from -- and why some are ...

Earth's rocky layers are mysteriously low in nitrogen compared with carbon and argon. A scientific team explored our planet's molten youth using advanced quantum mechanical simulations, revealing ...

An iron meteorite from the core of a melted planetesimal (left) and a chondrite meteorite, derived from a ‘primitive’, unmelted planetesimal (right). Researchers have used the chemical fingerprints of ...

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 ...

Decades-old radioactive glass found blanketing the ground after the first nuclear test bomb explosion is being used by scientists to examine theories about the Moon's formation some 4.5 billion years ...
