For the study, NASA scientists compared recent readings of Jupiter's magnetic field with data collected several years earlier by missions such as Travel and Pioneer. Juno's multiple passages of Jupiter using his magnetometer provided a wealth of information about the planet's magnetic field as it exists today, and researchers quickly noticed the differences.

"Finding something as minute as these changes in something as huge as Jupiter's magnetic field was a challenge," Juno scientist Kimee Moore said in a statement. "Having a database of close observations over four decades has provided us with just enough data to confirm that Jupiter's magnetic field is indeed changing over time."

These small changes indicate that Jupiter is experiencing a phenomenon called secular variation, which also occurs here on Earth. On our own planet, secular variation is attributed to deep-seated changes, and in Jupiter, strong winds well below cloud tops are believed to drive change.

This is an important discovery for scientists who are still trying to deepen their knowledge of the Earth's magnetic field. The Juno team plans to continue tracking the evolution of Jupiter's magnetism.
