Jupiter’s Volcanic Moon Io – NASA

During its close flyby of Jupiter’s moon Io on December 30, 2023, NASA’s Juno spacecraft captured some of the most detailed imagery ever of Io’s volcanic surface. In this image, taken by the JunoCam instrument from about 930 miles (1,500 kilometers) above the moon, Io’s night side [left lobe] is illuminated by “Jupitershine,” which is … Read more

Danish Instrument Helps NASA’s Juno Spacecraft See Radiation – NASA

Using cameras designed for navigation, scientists count ‘fireflies’ to determine the amount of radiation the spacecraft receives during each orbit of Jupiter. Scientists with NASA’s Juno mission have developed the first complete 3D radiation map of the Jupiter system. Along with characterizing the intensity of the high-energy particles near the orbit of the icy moon … Read more

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

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. Another high-resolution picture of the icy moon, … Read more

NASA’s Juno Gives Aerial Views of Mountain, Lava Lake on Io – NASA

This animation is an artist’s concept of Loki Patera, a lava lake on Jupiter’s moon Io, made using data from the JunoCam imager aboard NASA’s Juno spacecraft. With multiple islands in its interior, Loki is a depression filled with magma and rimmed with molten lava.
