This composite image, derived from data collected by the JIRAM instrument aboard NASA’s Juno orbiter, shows the central cyclone at Jupiter’s north pole and the eight cyclones that encircle it. JIRAM collects data in infrared, and the colors in this composite represent radiant heat: the yellow (thinner) clouds are about 9 degrees Fahrenheit (minus 13 degrees Celsius) in brightness temperature and the dark red (thickest) are around minus 181 degrees Fahrenheit (83 degrees Celsius).

The early ocean known as Arabia (left, blue) would have looked like this when it formed 4 billion years ago on Mars, while the Deuteronilus ocean, about 3.6 billion years old, had a smaller shoreline; both coexisted with the massive volcanic province Tharsis, located on the unseen side of the planet, which may have helped support the existence of liquid water; the water is now gone, perhaps frozen underground and partially lost to space, while the ancient seabed is known as the northern plains.

This color-enhanced image shows swirling cloud formations in the northern area of Jupiter’s north temperate belt. The image was taken on February 7 at 8:42 a.m. EST (5:42 a.m. PST), as Juno performed its eleventh close flyby of Jupiter. At the time the image was taken, the spacecraft was about 5,086 miles (8,186 km) from the tops of the clouds of the planet at a latitude of 39.9 degrees. Citizen scientist Kevin M. Gill processed this image using data from the JunoCam imager. Image credit: NASA / JPL-Caltech / SwRI / MSSS / Kevin M. Gill.
