New Plasma Wave Observations from Earth’s Magnetosphere

by Terri Cook, EOS

The first simultaneous observations of multiple electromagnetic wave types in Earth’s magnetosphere may inaugurate a new field of inquiry into cross-frequency wave interactions.

Plasmas are swirling mixtures of gas so hot that many of the constituent atoms have been stripped of their electrons, creating a dynamic field of both negatively and positively charged particles that are strongly influenced by magnetic and electrical fields. Plasmas account for more than 99% of matter in the universe and can disrupt satellite navigation systems and other technologies, but scientists are still working to understand the fundamental processes occurring within them.
