NASA scientists are reshaping the basic understanding of the kinetic Alfvén wave in space. 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 provides observational proof of a 50-year-old theory and reshapes the basic understanding of the kinetic Alfvén wave...
