NASA’s Juno spacecraft, currently orbiting Jupiter, routinely captures stunning views of the giant planet’s turbulent atmosphere, providing a treasure-trove of data for researchers and citizen-scientists like Seán Doran, who carries out sophisticated processing of raw imagery from the spacecraft’s JunoCam public-outreach camera. This view captures Jupiter’s Great Red Spot during Juno’s seventh low-altitude pass.
Scientists using the NASA/ESA Hubble Space Telescope have produced new maps of Jupiter that show the continuing changes in its famous Great Red Spot. The images also reveal a rare wave structure in the planet’s atmosphere that has not been seen for decades. This is the first in a series of annual portraits of the solar system’s outer planets which will help researchers study how they change over time.
A team of scientists has documented atmospheric changes on Io, Jupiter’s volcanically active satellite, as the giant planet casts its shadow over the moon during daily eclipses. Io’s thin atmosphere collapses as the sulfur dioxide gas emitted from volcanoes freezes when shaded by Jupiter. The atmosphere reforms when Io moves out of eclipse and the ice sublimates.
