Yesterday, we posted some incredible photos from the Juno Probe’s 29th flyby of Jupiter. Juno is in a highly elliptical orbit. It buzzes the planet at an altitude of 4,200km and then sweeps out to 8.1 million. Completing this circuit every 53 days, Juno only spends 2 hours within close proximity to Jupiter reducing the probe’s exposure to harmful radiation of high energy particles accelerated by Jupiter’s magnetic field.Continue reading “See a 360 Degree Juno-Eye View of Jupiter During an Io Eclipse”
Artist Mik Petter has created a vibrant new piece of art based on JunoCam images of Jupiter’s Great Red Spot (GRS). The piece makes use of fractals, which are recursive mathematical creations; increasingly complex patterns that are similar to each other, yet never exactly the same.Continue reading “Artwork Inspired by Jupiter’s Great Red Spot”

Though it looks like it to us, Jupiter’s clouds do no form a flat surface. Some of its clouds rise up above the surrounding cloud tops. The two bright spots in the right center of this image are much higher than the surrounding clouds.Continue reading “Clouds On Jupiter Rising Up Above the Surrounding Atmosphere”
The JunoCam onboard NASA’s Juno spacecraft continues to provide we Earthbound humans with a steady stream of stunning images of Jupiter. We can’t get enough of the gas giant’s hypnotic, other-worldly beauty. This image of Io passing over Jupiter is the latest one to awaken our sense of wonder.
This image was processed by Kevin Gill, a NASA software engineer who has produced other stunning images of Jupiter.Continue reading “Yes, This is Actually the Shadow of Io Passing Across the Surface of Jupiter.”
There’s something about Jupiter that mesmerizes those who gaze at it. It’s intricate, dazzling clouds are a visual representation of the laws of nature that’s hard to turn away from. And even though the Juno spacecraft has been at Jupiter for almost three years now, and has delivered thousands of images of the gas giant’s colourful, churning clouds, we can’t seem to satisfy our appetite.Continue reading “The Latest Insanely Beautiful Image of Jupiter Captured by Juno”
Jupiter: a massive, lifeless gas giant out there on the other side of the asteroid belt. It’s a behemoth, containing 2.5 times as much mass as all the other planets combined. To top it off, it’s named after the Roman God of War.
Earth: a tiny rocky world, almost too close to the Sun, where life rises and falls, punctuated repeatedly by extinctions. Compared to Jupiter, it’s a gum-drop world: Jupiter is 317.8 times the mass of Earth. And Earth is named after a goddess in German paganism, or so we think.

For almost 200 years humans have been watching the Great Red Spot (GRS) on Jupiter and wondering what’s behind it. Thanks to NASA’s Juno mission, we’ve been getting better and better looks at it. New images from JunoCam reveal some of the deeper detail in our Solar System’s longest-lived storm.
In July of 2016, the Juno spacecraft established orbit around Jupiter, becoming the first spacecraft since the Galileo probe to study the planet directly. Since that time, the probe has been sending back vital information about Jupiter’s atmosphere, magnetic field and weather patterns. With every passing orbit – known as perijoves, which take place every 53 days – the probe has revealed more exciting things about this gas giant.

Earlier this week, on Monday, July 10th, the Juno mission accomplished an historic feet as it passed directly over Jupiter’s most famous feature – the Great Red Spot. This massive anticyclonic storm has been raging for centuries, and Juno’s scheduled flyby was the closest any mission has ever come to it. It all took place at 7:06 p.m. PDT (11:06 p.m. EDT), just days after the probe celebrated its first year of orbiting the planet.
And today – Wednesday, July 12th, a few days ahead of schedule – NASA began releasing the pics that Juno snapped with its imager – the JunoCam – to the public. As part of the missions’ seventh orbit around the planet (perijove 7) these images are the closest and most detailed look of Jupiter’s Great Red Spot to date. And as you can clearly see by going to the JunoCam website, the pictures are a sight to behold!
And as always, citizen scientists and amateur astronomers are already busy processing the images. This level of public involvement in a NASA mission is something quite new. Prior to every perijove, NASA has asked for public input on what features they would like to see imaged. These Points of Interest (POIs), as they are called, are then photographed, and the public has had the option of helping to process them for public consumption.
As Scott Bolton – the associate VP at the Southwest Research Institute (SwRI) and the Principle Investigator (PI) of the Juno mission – said in a NASA press release, “For generations people from all over the world and all walks of life have marveled over the Great Red Spot. Now we are finally going to see what this storm looks like up close and personal.” And in just the past two days, several processed images have already come in.
Consider the images that were processed by Jason Major – an amateur astronomer and graphic designer who created the astronomy website Lights in the Dark. In the image above (his own work), we see a cropped version of the original JunoCam image in order to put Jupiter’s Great Red Spot center-frame. It was then color-adjusted and enhanced to mark the boundaries of the storm’s “eye” and the swirling clouds that surround it more clearly.
On his website, Major described the method he used to bring this image to life:
“[T]he image above is my first rendering made from a map-projected PNG file which centers and fully-frames the giant storm in contrast- and color-enhanced detail… The resolution is low but this is what my “high-speed” workflow is set up for—higher resolution images will take more time and I’m anticipating some incredible versions to be created and posted later today and certainly by tomorrow and Friday by some of the processing superstars in the imaging community (Kevin, Seán, Björn, Gerald, I’m looking at you!)”
Above is another one of Major’s processed images, which was released shortly after the first one. This image shows the GRS in a larger context, using the full JunoCam image, and similarly processed to show contrasts. The same image was processed and submitted to the Juno website by amateur astronomers Amadeo Bellotti and Oliver Jenkins – though their submissions are admittedly less clear and colorful than Major’s work.
Other images include “Juno Eye“, a close up of Jupiter’s northern hemisphere that was processed by our good friend, Kevin M. Gill. Shown below, this image is a slight departure from the others (which focused intently on Jupiter’s Great Red Spot) to capture a close-up of the swirls in Jupiter’s northern polar atmosphere. Much like the GRS, these swirls are eddies that are created by Jupiter’s extremely high winds.
The Juno mission reached perijove – i.e. the point in its orbit where it is closest to Jupiter’s center – on July 10th at 6:55 p.m. PDT (9:55 p.m. EDT). At this time, it was about 3,500 km (2,200 mi) above Jupiter’s cloud tops. Eleven minutes and 33 seconds later, it was passing directly over the anticyclonic storm at a distance of about 9,000 km (5,600 mi); at which time, all eight of its instruments were trained on the feature.
In addition to the stunning array of images Juno has sent back, its suite of scientific instruments have gathered volumes of data on this gas giant. In fact, the early science results from the mission have shown just how turbulent and violent Jupiter’s atmosphere is, and revealed things about its complex interior structure, polar aurorae, its gravity and its magnetic field.
The Juno mission reached Jupiter on July 5th, 2016, becoming the second probe in history to establish orbit around the planet. By the time the mission is scheduled to end in 2018 (barring any mission extensions), scientist hope to have learned a great deal about the planet’s structure and history of formation.
Given that this knowledge is likely to reveal things about the early history and formation of the Solar System, the payoffs from this mission are sure to be felt for many years to come after it is decommissioned.
In the meantime, you can check out all the processed images by going to the JunoCam sight, which is being regularly updated with new photos from Perijove 7!
