The Juno spacecraft has been in the gravitational embrace of the planet Jupiter for a month now, and is quickly approaching the moment it will ignite its thrusters, and enter into orbit over Jupiter's poles.
Juno may have some very interesting things to see, if aurorae spied by the Hubble Space Telescope in recent weeks continue to swirl around Jupiter's north pole.
