Another Webb infrared image of Jupiter released
Click for original image.
The science team for the James Webb Space Telescope today released another infrared false-color image of Jupiter, this time processed for science instead of calibration of the telescope after launch.
That image is to the right, reduced to post here. From the caption:
Several exposures in three different filters were assembled to create this mosaic, after being corrected for the rotation of the planet. The combination of filters yields an image whose colors denote the height of the clouds and the intensity of auroral emissions.
The F360M filter (mapped to the red-orange colors) is sensitive to light reflected from the lower clouds and upper hazes. The red features in the polar regions are auroral emissions, caused by ions excited through collisions with charged particles at altitudes up to 1000 km above the cloud level. Auroral emission in red is evident in the northern and southern polar regions and reaches high above the limb of the planet. In the F212N filter (mapped to yellow-green colors), the gaseous methane in Jupiter’s atmosphere absorbs light; the greenish areas around the polar regions come from stratospheric hazes 100-200 km above the cloud level. The stratospheric haze that appears green in this composite is also concentrated in the polar regions, but extends down to equatorial latitudes and can also be seen along the limbs (edges) of the planet. The cyan channel holds the F150W2 filter, which is primarily sensitive to reflected light from the Jupiter’s deeper main cloud level at about one bar.
The Great Red Spot, the hazy equatorial region and myriad small storm systems appear white (or reddish-white) in this false-color image. Regions with little cloud cover appear as dark ribbons north of the equatorial region. Some dark regions — for example, those next to the Great Red Spot and in cyclonic features in the southern hemisphere — are also dark-colored when observed in visible wavelengths.
This image is part of the telescope’s early release science program.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

Beautiful image. The quality of the Webb images is impressive. I think this one might make excellent wallpaper for my desktop.
The sharpness and detail are frankly at the level we’ve come to expect probes in close vicinity.
I wonder what we can get out of JWST once we point it at the ice giants?
Humbling.
“How many are your works, Lord!” (Ps 104:24)
It looks very much like the Great Red Spot leaves eddies in it’s wake. Of course, these are planet-sized
If climate models attempting to describe Earth are as good as they are claimed to be, they should also be pretty good for describing Jupiter’s atmospheric/climate behaviors.
They’re really good for describing the same for the moon. No?
If current Earth climate models are to be considered the Swiss army knives of climate explanations, they should also be able to do Jupiter and Mercury, too, no?
Why would climate scientists not be able to describe Jupiter and Mercury with the same accuracy they claim to be able to explain Earth?
Mercury’s atmosphere rubs against a rock surface. Jupiter’s atmosphere rubs against a liquid surface. Earth’s atmosphere rubs against both rocks and liquids.
If you can explain the most complex system in detail, why can’t you explain the less complex systems?
Oh.
