NASA’s $1 billion Juno spacecraft, launched in August 2011, took five years to reach and settle into orbit around the gas giant, which is more than 415 million miles from Earth.
The probe (with a size of a basketball court) has so far photographed Jupiter’s poles for the first time, detected bizarre cloud formations, recorded mysterious auroras, and scanned deep into the planet’s thick cloud tops.
Traveling above Jupiter at more than 130,000 miles per hour, NASA’s $1 billion Juno probe took its ninth set of stunning flyby images on October 24. What happened was the sun slipped between the giant planet and Earth for more than a week, and it blocked the spacecraft from beaming home its precious bounty of data.
Now that the conjunction is over, however, new raw image data from Juno’s ninth perijove — as the spacecraft’s high-speed flybys are called — has poured in. Researchers posted it all online on Tuesday, and a community of amateurs and professionals has been busily processing the data to yield colorful and stunning new pictures of Jupiter.
“JunoCam is a wide-angle camera designed to capture the unique polar perspective of Jupiter offered by Juno’s polar orbit,” says a research paper from Southwest Research Institute, San Antonio, TX.
“JunoCam’s four-color images include the best spatial resolution ever acquired of Jupiter’s cloud tops. It will look for convective clouds and lightning in thunderstorms and derive the heights of the clouds. It will support Juno’s radiometer experiment by identifying any unusual atmospheric conditions such as hotspots.”
This is the camera system that is currently peering at the poles of the largest planet in our solar system as Juno flies by on pass after planetary pass.
Here are some fresh, close-up images of Jupiter, along with other unbelievable views captured from earlier perijoves. Enjoy!
In the most recent flyby, as with the previous eight, Juno’s flyby started over Jupiter’s north pole.
The spacecraft then swept within a few thousand miles of the gas giant, capturing stunning high-resolution views of its cloud tops.
At its closest approach to Jupiter during each flyby, the robot briefly becomes the fastest human-made object in the solar system, reaching speeds of around 130,000 miles per hour.

Then Juno flew back out into deep space, passing over Jupiter’s south pole on its exit. Churning storms at the poles constantly change their appearance.

The planet’s atmosphere is a turbulent mess of hydrogen and helium gases. The planet’s atmosphere is a turbulent mess of hydrogen and helium gases.
There are also traces of molecules like ammonia, methane, sulfur, and water, which give the clouds different colors and properties. There are also traces of molecules like ammonia, methane, sulfur, and water, which give the clouds different colors and properties.
The mixture sometimes creates features that look like faces (as seen on the left in this image). The mixture sometimes creates features that look like faces (as seen on the left in this image).
Other times, shining-white clouds fill up most of a band.
Many cloud bands have features called chevrons. These atmospheric disturbances blow at several hundreds of miles per hour and sometimes zig-zag through a band, or punch through into others.
In this older view of Jupiter, from Juno’s eighth perijove, two cloud bands battle for dominance — one of which contains a swirling storm many times larger than a hurricane on Earth.
The spacecraft will continue to document Jupiter for as long as NASA can keep it going. But not forever.
