These dramatic swirls on Jupiter are atmospheric features. Clouds swirl around a circular feature in a jet stream region.
Is that a dolphin on Jupiter? No, but it definitely looks like one. It's actually a cloud that looks like it's swimming through cloud bands along the South Temperate Belt.
This composite image, derived from data collected by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard NASA's Juno mission to Jupiter, shows the central cyclone at the planet's north pole and the eight cyclones that encircle it.
This striking image of Jupiter was captured by NASA's Juno spacecraft as it performed its eighth flyby of the gas giant.
Algorithmic-based scaling and coloring reveal a vivid look at the Great Red Spot in July 2017.
Jupiter's Great Red Spot is a storm with a 10,000-mile-wide cluster of clouds in July 2017.
Color enhancements offer a detailed look into the Great Red Spot.
NASA configured this comparison of its own image of Earth with an image of Jupiter taken by astronomer Christopher Go.
This artist's concept shows the pole-to-pole orbits of the NASA's Juno spacecraft at Jupiter.
This image shows Jupiter's south pole, as seen by NASA's Juno spacecraft from an altitude of 32,000 miles (52,000 kilometers). The oval features are cyclones, up to 600 miles (1,000 kilometers) in diameter. Multiple images taken with the JunoCam instrument on three orbits were combined to show all areas in daylight, enhanced color and stereographic projection.
An even closer view of Jupiter's clouds obtained by NASA's Juno spacecraft.
Jupiter's north polar region comes into view as NASA's Juno spacecraft approaches the giant planet. This view of Jupiter was taken when Juno was 437,000 miles (703,000 kilometers) away during its first of 36 orbital flybys of the planet.
This infrared image gives an unprecedented view of the southern aurora of Jupiter, as captured by NASA's Juno spacecraft on August 27, 2016. Juno's unique polar orbit provides the first opportunity to observe this region of the gas-giant planet in detail.
NASA's Juno spacecraft has sent back its first photo of Jupiter, left, since entering into orbit around the planet. The photo is made from some of the first images taken by JunoCam and shows three of the massive planet's four largest moons: from left, Io, Europa and Ganymede.
An illustration depicts NASA's Juno spacecraft entering Jupiter's orbit. Juno will study Jupiter from a polar orbit, coming about 3,000 miles (5,000 kilometers) from the cloud tops of the gas giant.
This was the final view of Jupiter taken by Juno before the on-board instruments were powered down to prepare for orbit. The image was taken June 29, 2016, while the spacecraft was 3.3 million miles (5.3 million kilometers) from Jupiter.
NASA's Hubble Space Telescope captured images of Jupiter's auroras on the poles of the gas giant. The observations were supported by measurements taken by Juno.
This artist rendering shows Juno orbiting Jupiter.
Jupiter and the gaseous planet's four largest moons -- Io, Europa, Ganymede and Callisto -- are seen in a photo taken by Juno on June 21, 2016. The spacecraft was 6.8 million miles (10.9 million kilometers) from the planet.
Juno made a flyby of Earth in October 2014. This trio of images was taken by the spacecraft's JunoCam.
Three Lego figurines are flying aboard the Juno spacecraft. They represent the Roman god Jupiter; his wife, Juno; and Galileo Galilei, the scientist who discovered Jupiter's four largest moons on January 7, 1610.
Jupiter was 445 million miles (716 million kilometers) from Earth when Juno was launched from Cape Canaveral, Florida, on August 5, 2011. But the probe traveled a total distance of 1,740 million miles (2,800 million kilometers) to reach Jupiter, making a flyby of Earth to help pick up speed.
Technicians use a crane to lower Juno onto a stand where the spacecraft was loaded with fuel for its mission.
Technicians test the three massive solar arrays that power the Juno spacecraft. In this photo taken February 2, 2011, each solar array is unfurled at a Lockheed Martin Space Systems facility in Denver.
