With an atmosphere that best resembles the sun, Jupiter is predominantly made up of hydrogen and helium, with trace amounts of ammonia, sulfur, methane and water vapor. Strong east-west winds in the planet's upper atmosphere travel at 400 mph, with dark belts and light zones reflecting different compositions of chemicals. Thanks to NASA's Juno spacecraft (which has been orbiting Jupiter since July 2016), we can admire Jupiter's beauty up-close. On Feb. 12, Juno performed its 18th flyby from about 8,000 miles away and captured the image seen above. The swirling clouds and circular area are part of a jet stream region in the northern hemisphere called "Jet N6." Citizen scientist Kevin M. Gill created this color-enhanced image by using data made available to the public.

As you move through the series, you can still see the white oval, albeit from a slightly different angle from Juno. You can also see the Little Red Spot (second and third images) and the North North Temperate Belt (fourth and fifth images.) This sequence was taken on the night of July 15, 2018 and the very early morning hours of July 16, as Juno did its 14th close flyby of Jupiter. This color-enhanced image of a cloud system in Jupiter's Northern Hemisphere was captured in October 2017.

The image was captured in October 2017 by Juno at a distance of less than 12,000 miles above the Jovian cloud tops. According to NASA scientist Jack Connerney, deputy principal investigator of the Juno mission, previous images of Jupiter have been taken at the equator where orange, red, and white hues dominate. But that's not what Jupiter looks like from all angles. "And when you look down from the poles ... it's an entirely different image. It's almost — well, I wouldn't say almost — it is unrecognizable as Jupiter. And what you see are these cyclones, groups of cyclones, dancing around the poles, intricate storms," Connerney told NPR. This time-lapse video from NASA shows how the cyclones dance around the poles. The video was created by digitally extrapolating two images that were taken nine minutes apart and attempts to show how the clouds move in 29 hours. "The computer animation shows that circular storms tend to swirl, while bands and zones appear to flow," said NASA. Juno snapped this photo of Jupiter during its seventh close pass in May 2017.

As you might expect, they're a bit different from the icy storms we experience here on Earth. "It's probably mostly ammonia ice, but there may be water ice mixed into it, so it's not exactly like the snow that we have [on Earth]," Bolton told Space.com. "And I was using my imagination when I said it was snowing there — it could be hail." A view of Jupiter's south pole as captured by the Juno spacecraft.

The massive tempests are densely grouped and seemingly rub together across the entire polar region. "What you see is incredibly complex features, the cyclones and anticyclones all over the poles," Bolton told The New York Times.

NASA's Juno spacecraft took this image of Jupiter's northern hemisphere from 8,292 miles above the cloud tops in late 2017. (Photo: NASA/JPL/SwRI/MSSS/Gerald Eichstädt/Seán Doran) Juno has been able to get some remarkably close-up views of Jupiter's clouds. For example, the probe was a little more than one Earth diameter away when it took the image above showing cloud tops in the gas giant's northern hemisphere. "Jupiter completely fills the image," NASA explains, "with only a hint of the terminator (where daylight fades to night) in the upper right corner, and no visible limb (the curved edge of the planet)." For a sense of scale, one pixel in this image is roughly equivalent to 5.8 miles (9.3 kilometers). NASA's Juno spacecraft captured what appeared to be a dolphin swimming through the tumult of Jupiter's atmosphere. (Photo: NASA / Brian Swift / Seán Doran) Sometimes, the massive swirls of clouds and storms dancing across Jupiter's surface can even take on some familiar shapes. Visual artist Seán Doran spotted what appeared to look like a dolphin swimming through a series of images captured by Juno in October 2018. Unlike the animal-shaped clouds we see when looking up at the sky, Doran estimates this playful one was huge — at least the size of Earth. Dubbed the 'Dragon's Eye' by NASA's Jet Propulsion Laboratory, the white oval in this photo is known as an anticyclonic storm.

The white oval, dubbed the "Dragon's Eye" by NASA's Jet Propulsion Laboratory, is an anticyclonic storm. This phenomenon, which also occurs on Earth, is so-named due to winds around a storm flowing in a direction opposite to that of the flow about a region of low pressure. Jupiter's Great Red Spot is also an example of an anticyclonic storm. A view of a massive storm on Jupiter as captured by the Juno spacecraft in October 2017 from a distance of only 6,281 miles.

NASA will then make a decision to either extend the spacecraft's mission or, like Cassini's tour of Saturn, send it into a death plunge toward the gas giant to avoid contaminating nearby worlds. "We're very excited about what we've seen so far, and every time we fly by the planet it's like Christmas time," Juno project manager Rick Nybakken told SpaceFlight Now. "The data is stunning."
