It’s been the turn of theto delight us with images of Jupiter that it takes in the realm of and that image processing techniques allow us to see translated into false .
the @NASAWebb keep knocking! After the first images of nebulae and galaxies revealed in mid-July, it is now Jupiter’s turn to be examined by the NIRCAM instrument. The image is a composite of three wavelengths at 3.6, 2.12 and 1.5 microns. pic.twitter.com/yoZxXPMU3w

We can convince ourselves of this with the latest images put online by NASA and theand which relate to observations of Jupiter in infrared on July 27, 2022 as part of a demonstration program Early Science co-led by a from the Paris Observatory – PSL, Thierry Fouchet, working at Lesia (Laboratory for space studies and instrumentation in ).
Comments from this astrophysicist as well as from the other director of the program can be found on the Paris Observatory – PSL website. Early Science,. She is known as well for leading the team using the telescope having imaged the impact of the comet with Jupiter, only for his .
“We have never seen Jupiter like this! »
Thus for the planetologist: “ We have never seen Jupiter like this. It’s all pretty amazing. We didn’t really expect such a good picture, to be honest. It is truly remarkable that we can see details of Jupiter along with its rings, tiny satellites and evenin a single image. She adds : Although we have already observed many of the features of Jupiter, the access to infrared offered by JWST opens up a new perspective. The combination of images and spectra at near and mid-infrared wavelengths will allow us to study the interaction between the dynamics of the chemical composition and the vertical temperature structure in and above the and in the auroral regions. »
Still on the Lesia website, we find the following comment from Thierry Fouchet regarding the image above: This image illustrates the sensitivity and dynamic range of the instrumentof the JWST. She reveals the them and the bright vortices of Jupiter’s atmosphere and simultaneously provides a picture of the dark ring system, a million times fainter than the planet, as well as the moons Amalthea and Adrastea, which are about 200 and 20 kilometers in diameter respectively. . This image alone illustrates the scientific objectives of our program who study the dynamics and of the planet itself, its rings and its system of satellites. »
And now Jupiter in the eyes of the James-Webb Space Telescope
Article ofpublished on 07/18/2022
The James-Webb Space Telescope didn’t just probe celestial objects millions or billions awayhe also pointed his big on Jupiter and its potentially habitable moon, Europa. Here too, the result exceeds the expectations of the .
Theunveiled on July 12, and effectively inaugurating the scientific campaign of the largest and most powerful space telescope ever launched, amazed us over their discoveries on Tuesday. There’s so much to say about each of them, from the farthest reaches of revisited – ” » -, to the from the southern ring, passing through a nebula with its staggering “reliefs” of detail, and not to mention the intertwined galaxies of Stefan’s Quintet, where one can even see individual… In short, already iconic images. An impressive leap forward in the details obtained thanks to its instruments for cosmic objects distant from several tens of thousands of light-years… to several billion light-years. And “this is just the beginning! » (this is only the beginning), repeated the astrophysicists who participated in their live presentations by NASA.
And now, Jupiter!
Another surprise and beauty registered on July 12 in the Mikulski archives of the STSI (Space Telescope Science Institute) as part of the James-Webb commissioning, a familiar and nearby object: Jupiter. Astronomers are delighted and do not hide their admiration for the quality of the images and data obtained.
Curious to see what it would be like to observe such a close and brilliant celestial body, they were not disappointed: these portraits of the largest planet in theindeed reveal its very discreet rings (image of NIRCam), the moon Europe and the small Metis and Thebes. “The images of Jupiter in the narrowband filters were designed to provide beautiful images of the entire disk of the planet, but the wealth of additional information about very faint objects (Métis, Thebes, the main ring, them ) in these images taken with about a minute of exposure was a very pleasant surprise”says John Stansberry, who takes care of the NIRCam instrument.
Ok, here’s a for real JWST Jupiter. The read noise (vertical lines) is…significant. But, look, the GRS has its own diffraction spikes. This is the NIRCam data with f322w2-f323n overlaid in red and f212n in sky blue. Bg is grayscale combo of both. pic.twitter.com/VWNXFBLpwE

As it concernsone of the four Galilean satellites of Jupiter (visible in binoculars), we can also see its shadow projected on Jupiter, just to the left of the famous . This potentially habitable satellite which shelters a global ocean under a thick crust of ice will be a privileged target for astronomers who hope to scrutinize and study its with the space telescope. “I think that’s just one of the coolest things we’ll be able to do with this telescope in the solar system.”says Stefanie Milam, researcher in planetary sciences at the GSFC (Goddard Space Flight Center) from NASA.
has not finished surprising us and the scientific images of the Universe will rain down for our greatest pleasure, showing us structures and objects that we had never seen before.
