Photos: Juno, meet Jupiter This jack-o-lantern-esque view of Jupiter is a mosaic of images taken by the Gemini North telescope in Hawaii. The bright spots represent Jupiter's internal heat escaping through holes in the planet's massive cloud cover. Hide Caption 1 of 28

Photos: Juno, meet Jupiter Part of Jupiter's southern equatorial region can be seen in this image captured by Juno's JunoCam imager. But it's flipped to show the expanse of Jupiter's atmosphere, with the poles to the left and right, rather than top to bottom. Hide Caption 2 of 28

Photos: Juno, meet Jupiter In this image captured by Juno, six cyclones remain stable at Jupiter's south pole. A small cyclone, seen at the bottom right in yellow, has recently joined the party. Hide Caption 3 of 28

Photos: Juno, meet Jupiter 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. Hide Caption 6 of 28

Photos: Juno, meet Jupiter 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. Hide Caption 7 of 28

Photos: Juno, meet 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. Hide Caption 14 of 28

Photos: Juno, meet Jupiter 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. Hide Caption 16 of 28

Photos: Juno, meet Jupiter 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. Hide Caption 17 of 28

Photos: Juno, meet Jupiter 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. Hide Caption 18 of 28

Photos: Juno, meet Jupiter 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. Hide Caption 19 of 28

Photos: Juno, meet Jupiter 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. Hide Caption 20 of 28

Photos: Juno, meet 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. Hide Caption 21 of 28

Photos: Juno, meet Jupiter 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. Hide Caption 26 of 28
