Earth's Mantle Nitrogen Content Is Comparable To That Found In Its Nitrogen-Rich Atmosphere.

A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published today in AGU Advances, AGU's journal for high-impact, open-access research and commentary across the Earth and space sciences.

A magnetosphere forms around any magnetized object, such as a planet, that is immersed within a stream of ionized gas, called plasma.

UCLA scientists have discovered a new source of super-fast, energetic electrons raining down on Earth, a phenomenon that contributes to the colorful aurora borealis but also poses hazards to satellites, spacecraft and astronauts.

Ozone may be weakening one of the Earth's most important cooling mechanisms, making it a more significant greenhouse gas than previously thought, research has found.
