There`s a radio wave surrounding around the earth along with electron ion and when they bangs to the surface this frequency detected by the radio detectors are called "whistler" and now scientists have observed burst like this in more detail than ever before. Whistlers are the lightning strikes and discovered a century ago,usually travel along the magnetic field lines.On 14 August , researchers from the
University of California, Los Angeles reported that they've produced whistlers in a plasma —
a very electrically active, difficult-to-control, gas-like state of matter — in their
laboratory, and observed their shapes. That means scientists now know more about how to shape a whistler than ever before. And that turns out to be a very big deal: Back in 2014, a team of Italian researchers proposed that whistler waves could be used as the driving force of a plasma thruster to drive a craft through space, thanks to their ability to push on matter. A plasma thruster of this sort would, in theory, require very little fuel mass to push a spacecraft along at high speeds.
But if a machine like that is going to work, the researchers wrote, scientists will first need studies like this to understand whistlers well enough to use them.
