Welcome to Discussion

Jupiter has a dynamic atmosphere where winds in the belts (brown) and zones (white) go in opposite directions. Storms develop and evolve, and other atmospheric features come and go.  An imaging team, the scientists that operate the cameras on NASA missions, always begins with a discussion phase that covers what we know and what we would like to learn.  You are a member of our JunoCam virtual imaging team.  This discussion page is a place for general thoughts about Jupiter and your questions and ideas.

Cylindrical Map

We use images from amateur astronomers (uploaded on the Planning page) to create a new cylindrical map every 14 days. This is the latest one! We have identified long-lived storms as Points of Interest (POI’S) and invite you to share your thoughts about them.

Notes about cylindrical maps and perijove passes

In its 53-day orbit, Juno spends most of the time distant from Jupiter. The spacecraft swoops from the north to the south pole in just 2 hours, which we call a "perijove pass".  That means that the close-up images JunoCam can take are restricted to just a swath of longitude, not the entire globe.   JunoCam points out along the solar arrays, and for most perijove passes the solar arrays are oriented to the sun, so JunoCam is pointing 90 degrees from the sun.

As time goes on Juno’s orbit is moving around Jupiter.  The most distant point of the orbit is moving to Jupiter’s night side.  Perijove (“PJ”), the closest point in the orbit, is moving more to the sun-side, which impacts JunoCam because this moves Jupiter off to the side of our field of view.   A simple comparison of the images collected at PJ9 to PJ10 in the Processing gallery shows how the geometry is changing the shape of the images.

For those of you who have been participating since the beginning, we initially used this page to identify Points of Interest (POIs).  We would then vote on which POI’s to take pictures of on any given perijove pass.  This was a concept that we developed for Juno’s 14-day mission plan.   The decision to stay in a 53-day orbit means that the viewing geometry changes more and this impacts our ability to predict what will be in JunoCam’s field of view.   (To see the POI’s that were selected in the past you can go to the Voting page.)

    How does the radiometers work? I guess a model is used to relate frequency emission of various substance, the attenuation of the signal with depth etc. How could that be calibrated on earth?

    These images of Jupiter and Ganimede was captured on August 29, 2021 from city of Cremona (Northern Italy) through a 255mm F20 Maksutov Rumak telescope with Zwo ASI 224MC CMOS camera, IR Blocking filter and ADC Corrector. Video of 120sec at 30 fps with Sharpcap, was stacked 1800/3600 frames. Images processed with Astrosurface, registax, Fitswork, Camera Raw.

    Wich is the Clyde's Spot in these images ? - Planet Jupiter taken from Cremona (Northern Italy) through a 255mm F20 Maksutov Rumak telescope + Zwo ASI 224MC CMOS color camera + ADC Corrector + Baader IR Pass 685nm filter / IR Blocking filter. Stacked 400/3600 frames at 30 fps. Software videocapture Sharpcap. Frames was aligned and stacked by Autostakkert. Images has been processed with software Astrosurface, Fitswork, Camera Raw. I so obtained an RGB image and Monochromatic image. Finally these RGB and Monochromatic images was added together. About the Clyde's Spot I have indicated the area in wich perhaps can be seen this detail. Can you confirm wich is exactly the Clyde's Spot in my images ? Many thanks and best regards.

    The Dolphin-shaped clouds seen in one set of Juno images are forms which may be precursors of forms in life in fluid media even on Earth. Other similar relationships, then, may be discovered, which would involve phenomena such as diffusion, m*c^2=h*nu, heat and thermodynamics, concentration gradients and so on.
