Chorus waves are a class of frequency-chirping, whistler-mode plasma waves that are routinely observed in Earth’s near-space environment. Chorus waves play a key role in various physical processes including the formation of the Earth’s Van Allen radiation belts, the pulsating aurora, and the... Read More

NASA is developing a new type of detector that will provide insight into the formation and structure of the universe. Many of the radiative and mechanical interactions that shape the interstellar medium of galaxies and drive galactic evolution (e.g., shock waves from stellar winds and jets,... Read More
