Juno Finds Changes in Jupiter's Magnetic Field

Mars Imaged by Hubble

NASA's Juno mission to Jupiter made the first definitive detection beyond our world of an internal magnetic field that changes over time, a phenomenon called secular variation. Juno determined the gas giant's secular variation is most likely driven by the planet's deep atmospheric winds.

Jupiter

New Earth-based telescope observations show that auroras at Jupiter's poles are heating the planet's atmosphere to a greater depth than previously thought -- and that it is a rapid response to the solar wind.
