The infrared variations seen by a ground-based telescope in Jupiter's North Equatorial Belt between May 2001 and December 2011.

An article published in the journal “Nature Astronomy” reports a solution to the mystery of the change in color of some belts of the planet Jupiter’s atmosphere. A team of researchers used data collected by NASA’s Juno space probe to link those changes to the planet’s magnetic field. Scientists already knew the connection with variations in the infrared band, which means the propagation of electromagnetic field energy, about 50 kilometers below Jupiter’s surface. This new study brings evidence that the variations may in turn be caused by waves produced by the planetary magnetic field at depth.
