” Combined with the deep field images released a few days ago, these pictures of Jupiter show the full grasp of what Webb can observe, from the faintest, most distant observable galaxies to planets in our own cosmic yard that you can see with the naked eye from your real backyard,” stated Bryan Holler, a researcher at the Space Telescope Science Institute in Baltimore, in a NASA article. Holler became part of the group who assisted prepare these observations.
This view from JWSTs NIRCam instruments short-wavelength filter plainly reveals the distinct cloud bands around the huge world along with the Great Red Spot, Jupiters popular enormous storm. Scientists say the iconic spot appears white in this image since of the way Webbs infrared image was processed.
After the huge reveal earlier this week of the James Webb Space Telescopes first full color images and spectra of the universe, the science team has now launched information from closer to home. These latest data are actually simply engineering images, created to check JWSTs capability to track solar system targets, as well as test out how the team can produce images from the information.

Scientists were extremely excited to see these images because they are evidence that JWST can observe the satellites and rings near brilliant solar system items such as Jupiter, Saturn, and Mars. Jupiter and its moon Europa are seen in this animation made from 3 images taken through the NIRCam instrument 2.12 micron filter.
After the huge reveal previously this week of the James Webb Space Telescopes very first complete color images and spectra of the universe, the science group has now launched data from closer to house. These most current data are really just engineering images, created to test JWSTs capability to track solar system targets, as well as test out how the group can produce images from the information. The quality and detail in these test images have delighted the mission scientists.
Clearly visible at left is Europa, which is seen as a dark spot with intense edges, nd remarkably, in the infrared, Europa is brilliant enough to produce diffraction spikes. Diffraction spikes originate from the hexagonal shape of the mirror segments, diffracting the light from bright objects like stars, or in this case a nearby moon.
But look carefully, and Europas shadow can be seen to the left of the Great Red Spot. Other visible moons include Thebe and Metis, which are viewed as small, white areas.

Even Jupiters thin rings are noticeable in some of the new images, using JWSTs NIRcam long-wavelength filter image. The really scattered rings were very first found by the Voyager spacecraft in 1979.
” What JWST will provide for Jupiters rings is give beautiful image stability and quality, to identify ring structure, and its sources, sinks and advancement,” stated Heidi Hammel on Twitter, Hammel is a JWST interdisciplinary scientist who has early observing time on the telescope to study Jupiter.

Scientists were really eager to see these images due to the fact that they are proof that JWST can observe the satellites and rings near intense solar system things such as Jupiter, Saturn, and Mars. Some interesting upcoming observations is to utilize the brand-new space telescope to search for plumes of water gushing out of moons like Europa and Saturns moon Enceladus. Webb might have the ability to see the signatures of plumes transferring product on the surface area on Europa.
” I think thats simply one of the coolest things that well be able to do with this telescope in the solar system,” said Stefanie Milam, Webbs deputy task researcher for planetary science NASAs Goddard Space Flight.
Astronomer Judy Schmidt retrieved the JWST data of Jupiter to create this image, which she shared on Twitter. Even the Great Red Spot is bright enough with the NIRCam data to create diffraction spikes.
Ok, heres a for genuine JWST Jupiter. The read noise (vertical lines) is … substantial. Appearance, 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 combination of both. pic.twitter.com/VWNXFBLpwE— Judy Schmidt (@SpaceGeck) July 15, 2022.
However other uncommon features show up as well, and scientists arent sure yet if the “additional summary” on the eastern limb is real or an image artifact.
Heidi Hammel commented that her team noticed “that weird edge right and began discussing separated haze layers or air radiance.” This illustrates how scientists are still finding out how to analyze JWSTs infrared information. To reiterate, Hammel included, “The Jupiter teams are so fired up!”.
JWST also acquired these pictures of Jupiter and Europa crossing the telescopes field of view in 3 separate observations. This test showed the capability of the observatory to find and track guide stars in the area of intense Jupiter.

Researchers were really interested to check out how fast an item could be moving and still be tracked by JWST, and to do so, throughout the commissioning period, Webb tracked an asteroid called 6481 Tenzing, situated in the asteroid belt between Mars and Jupiter.
Engineers stated that JWST was developed with the requirement to track objects that move as quickly as Mars, which has an optimal speed of 30 milliarcseconds per second. Throughout commissioning, the Webb team conducted observations of numerous asteroids, and proved they can get valuable information with all of the science instruments for things going up to 67 milliarcseconds per second, which is more than twice the expected standard. They said it is “similar to photographing a turtle crawling when youre standing a mile away.

You can check out a paper from JWST scientists, who defined the performance of all of the telescopes instruments throughout the commissioning duration.
