NASA’s Juno Mission Captures the Colorful and Chaotic Clouds of Jupiter

During its 61st close flyby of Jupiter on May 12, 2024, NASA’s Juno spacecraft captured this color-enhanced view of the giant planet’s northern hemisphere. It provides a detailed view of chaotic clouds and cyclonic storms in an area known to scientists as a folded filamentary region. In these regions, the zonal jets that create the […]

NASA’s Juno Provides High-Definition Views of Europa’s Icy Shell

Imagery from the solar-powered spacecraft shows some intriguing features on the ice-encased Jovian moon. Images from the JunoCam visible-light camera aboard NASA’s Juno spacecraft supports the theory that the icy crust at the north and south poles of Jupiter’s moon Europa is not where it used to be.

NASA’s Juno Mission Spots Jupiter’s Tiny Moon Amalthea

NASA’s Juno mission captured these views of Jupiter during its 59th close flyby of the giant planet on March 7, 2024. They provide a good look at Jupiter’s colorful belts and swirling storms, including the Great Red Spot. Close examination reveals something more: two glimpses of the tiny moon Amalthea (see Figure B below). Figure […]

Jupiter’s Great Red Spot

This April 1, 2018, enhanced-color image of Jupiter’s Great Red Spot was captured by NASA’s Juno spacecraft. The image is a combination of three separate images taken as Juno performed its 12th close flyby of the planet. The Great Red Spot, a swirling oval of clouds twice as wide as Earth, has been observed on […]

NASA’s Juno Mission Measures Oxygen Production at Europa

The ice-covered Jovian moon generates 1,000 tons of oxygen every 24 hours – enough to keep a million humans breathing for a day. Scientists with NASA’s Juno mission to Jupiter have calculated the rate of oxygen being produced at the Jovian moon Europa to be substantially less than most previous studies. Published on March 4 […]

NASA’s Juno to Get Close Look at Jupiter’s Volcanic Moon Io on Dec. 30

The orbiter has performed 56 flybys of Jupiter and documented close encounters with three of the gas giant’s four largest moons. NASA’s Juno spacecraft will on Saturday, Dec. 30, make the closest flyby of Jupiter’s moon Io that any spacecraft has made in over 20 years. Coming within roughly 930 miles (1,500 kilometers) from the […]

NASA’s Juno Finds Jupiter’s Winds Penetrate in Cylindrical Layers

The finding offers deeper insights into the long-debated internal structure of the gas giant. Gravity data collected by NASA’s Juno mission indicates Jupiter’s atmospheric winds penetrate the planet in a cylindrical manner, parallel to its spin axis. A paper on the findings was recently published in the journal Nature Astronomy.
