Unraveling the nature of ‘whistlers’ from space in the lab

Scientists have presented research on a curious cosmic phenomenon known as ‘whistlers’ — very low frequency packets of radio waves that race along magnetic field lines. The study provides new insights into the nature of whistlers and space plasmas and could one day aid in the development of practical plasma technologies with magnetic fields, including spacecraft thrusters that use charged particles as fuel.
