We go into more detail about the role of magnetism in creating aurora and what “Bz” refers to.
What is the solar wind and what does it have to do with the aurora?
Radio astronomers are gearing up for a new generation of radio telescopes that will be based on radically new design concepts: a wide field of view and a high-fidelity snapshot capability. One such instrument is the Murchison Widefield Array (MWA), a radio telescope in the Australian outback. If such an instrument were to be built at high latitudes, it could provide a radio telescope’s view of auroral activity that could be used to forge a better understanding of what happens to plasma near the Earth during an auroral display.
