Jupiter’s Fast Traveling particles captured by Juno

NASA features results from Juno instruments that measured incredible speeds of particles around Jupiter.

NASA’s Juno Mission measured particles traveling close to the speed of light near Jupiter. Those speedy particles will help scientists learn more about how and where high-energy particles form.

An artists concept shows a planet at the top center with a blue band arcing around it in a horseshoe shape The blue band is labeled the magnetosheath The inner part of this blue band closest to the planet is labeled the magnetopause The outer edge of the blue band is labeled the bow shock Just outside the blue band to the lower left of it is a purple wedgeshaped area labeled the foreshock On the far left is a red shaded area with red arrows pointing from left to right appearing to push against the magnetosheath blue region and foreshock purple region labeled the stellar wind — As planets and stars travel through the streams of charged particles flowing across space, their magnetic fields act like obstacles. Incoming particles are slowed and deflected, forming a boundary called the bow shock. Just ahead of this boundary lies the foreshock, a variable region where magnetic conditions can accelerate some particles to nearly the speed of light.
