We learned about earth’s magnetosphere. It comes from the outer core and protects us from solar winds that blow particles at the earth. Our magnetosphere blocks the particles except for sometimes it doesn’t. Then the particles get into our atmosphere and make light shows called auroras (by Joel,7).
NASA just recorded the sound of the earth coming from the magnetosphere. It is called Earth’s Chorus and it sounds like birds chirping. Chorus waves might carry killer electrons which are dangerous for astronauts. You can listen to Earth’s song here. (by Titus, 8)
