And now, a word from Juno at Jupiter

Juno arrived at Jupiter in 2016. It’s in a 53-day orbit around the planet. Close sweeps past the planet are called “perijoves” (peri means “near”). Here are some spectacular images from the most recent sweep, Perijove 25, in February.

The Juno mission to Jupiter has been orbiting the giant planet since 2016, and NASA has made the raw images from Juno’s camera available to the public for processing. Click here if you want to help. Juno has a 53-day orbit around Jupiter, and close passes of the planet are called perijoves, from the Greek word peri meaning near. Images are now coming in from Juno’s most recent close sweep past the planet, Perijove 25, on February 17, 2020. We’ve also included some images on this page from the next-to-last sweep past Jupiter (Perijove 24) on December 26, 2019.

More than 40 slice-like partial images of Jupiter.

Here’s a mosaic of images of Jupiter, processed and assembled by Brian Swift from Perijove 24. He labeled this as a “collage [with] exaggerated contrast/color.” Image via NASA/ JPL-Caltech/ SwRI/ MSSS/ Brian Swift.

And here’s a cool image to end on, processed by citizen scientist Tanya Oleksuik and released by NASA on March 2, 2020. It’s from the second-to-last close sweep past Jupiter by Juno, in December 2019 (Perijove 24). Tanya created this color-enhanced image using data from the JunoCam camera.

Partial orbital view of Jupiter with two relatively small white ovals overlapping.

See the 2 white ovals merging, within the orange-colored band? NASA’s Juno spacecraft caught these 2 storms in the act of merging on December 26, 2019, a few days after a close flyby of the planet (Perijove 24). The 2 merging white ovals are anticyclones; they rotate counter-clockwise. The larger of the ovals has been tracked for many years, as it grew in size through mergers with other anticyclonic white ovals on Jupiter. Read more about this image.

Bottom line: Newly processed images from the days around the Juno spacecraft’s most recent low pass over the planet – called a “perijove” – on December 17, 2019.
