The JunoCam camera aboard NASA's Juno mission on Jupiter also provided the atmosphere.

JunoCam data found Atmospheric wave trains, towering atmospheric structures, which revolve one after the other as they cross the planet, with most of them moving are concentrated near the Jupiter equator.

The JunoCam imager has resolved smaller distances between individual wave crests than ever before. This research provides valuable information on both the dynamics of the Jupiter atmosphere and its structure in the regions under the waves.

"JunoCam has counted more different wave trains than any other space mission since Voyager," said Glenn Orton, a Juno scientist from NASA's Jet Propulsion Laboratory in Pasadena, California. "The trains, which consist of only two and up to several dozen waves, can have a distance of between about 65 kilometers and about 1,200 kilometers." The shadow of the wave structure in one picture allowed us to estimate the height of a wave at about 10 kilometers . "

Most of the waves are seen in elongated wave trains that extend in a westward direction, with wave crests perpendicular to the train's orientation. Other fronts in similar wave trains tilt significantly with respect to the orientation of the wave train, and still other wave trains follow oblique or meandering paths.

"The waves may appear close to other Jovian atmospheric features near vortexes or along streamlines and others have no relation to anything nearby," Orton said. "Some waves appear to converge, others appear to overlap, possibly at two different atmospheric levels, in one case wave fronts seem to radiate outward from the center of a cyclone."

Although analysis progresses, most waves are considered atmospheric gravitational waves expected – Up and down waves that form in the atmosphere above something disturbs the airflow, such as a thunderstorm ascent, interruptions of flow around other features, or some other disturbance that JunoCam does not detect.

The JunoCam instrument is uniquely qualified to make such a discovery. JunoCam is a visible light color camera that provides a wide-angle field of view to capture remarkable images of Jupiter's Poland and cloud tops. As Juno's eyes, it helps to create the context for the spacecraft's other instruments. JunoCam has been incorporated into the spacecraft primarily for public service purposes, though his imagery also helps the science team.

Juno launched from Cape Canaveral, Florida on August 5, 2011, and entered orbit around Jupiter on July 4. 2016. To date, it has completed 15 scientific passes on Jupiter. Junos 16th Science Run will be held on October 29th.

During these fly-bys Juno searches under the darkening cloud cover of Jupiter and explores his Northern Lights to learn more about the planet's origins, structure, atmosphere and magnetosphere.

JPL leads the Juno mission for principal investigator Scott Bolton of the Southwest Research Institute in San Antonio.

The Juno Mission is part of the New Frontiers Program, which is headed by NASA's Marshall Space Flight Center in Huntsville, Alabama, the scientific mission directorate. Lockheed Martin Space Systems of Denver, Colorado, built the spacecraft. JPL is a division of Caltech in Pasadena, California
