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, by the spacecraft’s Stellar Reference Unit (SRU), reveals signs of possible plume activity and an area of ice shell disruption where brine may have recently bubbled to the surface.

VLA teams up with Juno spacecraft to study Jupiter’s atmosphere, and ALMA reveals new details about Io’s volcanoes. While the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA) frequently reveal important new facts about objects far beyond our own Milky Way Galaxy — at distances of many millions or billions of light-years — they also are vital tools for unraveling much closer mysteries, right here in our own Solar System...

When a NASA spacecraft made its first full orbit around Jupiter, a University of Iowa instrument on board recorded haunting sounds befitting the Halloween season. The radio emissions cast by Jupiter’s auroras were recorded by the UI instrument, called Waves, as the Juno spacecraft traveled about 2,600 miles above Jupiter’s swirling clouds. Those emission recordings were then converted into sound files by UI engineers. The emissions from Jupiter were discovered in the 1950s but had never been analyzed from such a close vantage point, according to NASA.

“Jupiter is talking to us in a way only gas-giant worlds can,” says Bil...

NASA’s Juno spacecraft has sent back the 1st-ever images of Jupiter’s north pole, taken during the spacecraft’s first flyby of the planet with its instruments switched on. The images show storm systems and weather activity unlike anything previously seen on any of our solar system’s gas giant planets. Juno successfully executed the first of 36 orbital flybys on Aug. 27 when the spacecraft came about 2,500 miles above Jupiter’s swirling clouds. The download of 6 Mb of data collected during the 6h transit, from above Jupiter’s north pole to below its south pole, took one and a half days...
