Listen to the sound of Earth’s magnetic field as it’s pummeled by a solar storm

Our planet’s magnetic field is “singing.” The European Space Agency just released a recording of the frequencies generated as a solar storm collided with Earth’s magnetic field. It was released alongside new findings published in Geophysical Research Letters this week. What is it? Solar storms are the eruption of electrically charged particles ejected from the sun. When those particles reach Earth, they come into contact with the planet’s magnetic field. The first region of the magnetic field they hit is called the foreshock. The interactions of the particles with the foreshock causes the release of complex magnetic waves. Read more....
