In this animated GIF, the clouds on the periphery of some of Jupiter’s polar cyclones rotate counterclockwise, while the core of the cyclones rotate clockwise. The JunoCam images used for this animation were taken from altitudes of about 18,000 miles (28,567 kilometers) above Jupiter’s cloud tops. Citizen scientist Gerald Eichstädt […]

This artist’s conception of Jupiter’s icy moon Europa shows a hypothesized cryovolcanic eruption, in which briny water from within the icy shell blasts into space. A new model of this process on Europa may also explain plumes on other icy bodies. Credit: Justice Blaine Wainwright Scientists have theorized on the […]

New work led by Carnegie’s Matt Clement reveals the likely original locations of Saturn and Jupiter. Credits: NASA/JPL-Caltech/Space Science Institute Where were Jupiter and Saturn born? New work led by Carnegie’s Matt Clement reveals the likely original locations of Saturn and Jupiter. These findings refine our understanding of the forces that determined our […]

Composite image showing Jupiter’s moon Io in radio (ALMA), and optical light (Voyager 1 and Galileo). The ALMA images of Io show for the first time plumes of sulfur dioxide (in yellow) rise up from its volcanoes. Jupiter is visible in the background (Hubble).
