A weird whistling noise can be heard emanating from the giant gas planet as Juno approaches. The mysterious sound is caused by solar winds ploughing Jupiter at a million miles per hour in what is known as a bow shock.
William Kurth of the University of Iowa in Iowa City said in a Nasa statement: “The bow shock is analogous to a sonic boom. The solar wind blows past all the planets at a speed of about a million miles per hour, and where it hits an obstacle, there’s all this turbulence.”
