“Jupiter’s Great Blue Spot” –‘Incredible! Impacts Its Entire Magnetic Field’


Jupiter's Equator


“It is incredible that one narrow magnetic hot spot, the Great Blue Spot, could be responsible for almost all of Jupiter’s variation, but the numbers bear it out,” said Harvard’s Kimee Moore about the first definitive detection beyond our world by NASA’s Juno mission of an internal magnetic field that changes over time, a phenomenon called secular variation.


“Matter Unknown on Earth” –Radio Signals Reveal Deep Mysteries of Jupiter & Saturn

Cassini Mission


Radio signals from two NASA probes, Cassini at Saturn (above) and Juno at Jupiter, is allowing researchers to pierce the swirling clouds that hide the deep interiors of Jupiter and Saturn, where crushing pressure transforms matter into states unknown on Earth –“the two planets are more complex than we thought,” says Ravit Helled, a planetary scientist at the University of Zurich in Switzerland. “Giant planets are not simple balls of hydrogen and helium.”


“Explosive” –Juno Flyby Captures New Images of Io: Solar System’s Volcanic Epicenter


Jupiter's Moon Io


“We knew we were breaking new ground with a multi-spectral campaign to view Io’s polar region, but no one expected we would get so lucky as to see an active volcanic plume shooting material off the moon’s surface,” said Scott Bolton, principal investigator of the Juno mission. “This is quite a New Year’s present showing us that Juno has the ability to clearly see plumes.”
