NASA observations reshape basic plasma wave physics

When NASA's Magnetospheric Multiscale--or MMS--mission was launched, the scientists knew it would answer questions fundamental to the nature of our universe--and MMS hasn't disappointed. A new finding, presented in a paper in Nature Communications, provides observational proof of a 50-year-old theory and reshapes the basic understanding of a type of wave in space known as a kinetic Alfvén wave. The results, which reveal unexpected, small-scale complexities in the wave, are also applicable to nu...
