The James Webb Space Telescope also captured an image of Jupiter

On the historic day yesterday been detected First pictures and first data James Webb Space Telescope That officially opened the scientific observation campaign. The goals were the ones that were confirmed earlier, including also deep space image This made it possible to observe very distant galaxies, up to 13.7 billion light-years away. But this is only the beginning, as was said several times during the conference and JWST It might surprise us over the next few years (up 20 years oldthe date after which the motive can run out).

Jupiter “seen” by the Juno probe

Along with the Deep Space image (also called SMACS 0723) there was the image of the Carina Nebula, the characterization of the exoplanet WASP-96 b, the celestial body NGC 3132 (also known as the Southern Ring Nebula) and Stefan’s pentagram. A lot of information has emerged, such as detecting water vapor in the atmosphere of an exoplanet or observing objects too faint to be observed by Hubble. but the New space telescope He did not limit himself to looking too far away, among the first pictures there is also a picture JupiterThe Great gas giant It is (relatively) close to Earth.

James Webb Space Telescope and Jupiter Image

picture Jupiter It is not displayed during the conference but is in the file (publicly available) Call “Scientific Performance Characterization of JWST from Startup”. As shown at the beginning of the presentation, the . file James Webb Space Telescope It was also able to track solar system objects at a speed of 67 ms (such as the asteroid 2004 JX20). Just to be able to understand what performance JWSTalso Jupiter It is observed using different instruments (apparent speed of 3.3 mA / s).

Especially for the gas giant that was hired Nircam Scientists remember how difficult it is because dispersion (diffuse light) which can reduce the performance of tools as well Precision steering sensor (Who might have trouble observing stars close to such a bright object). Not a scientific observation but for engineering purposes, it was decided to pass the field of view from the field Nircam to the FGS so that we understand whether James Webb Space Telescope It meets expectations correctly.

The dispersion One issue to consider when trying to observe targets would be particularly close to other bright objects (for example, the moons of Jupiter in relation to Jupiter). especially Nircam Use filters F212N (2.12 µm) and F323N (3.23 µm) with an exposure time of 75 inches.

This also made it possible to immortalize the moons of Europa, Thebes and Metis, as well as the faint ring that surrounds them. Jupiter (much less visible than Saturn). In the image captured with the F212N filter, it is also possible to see the shadow of the Metis satellite near the Great Red Spot which is not visible with the F323N filter. Let’s remember that these are “lonliness” Pictures dedicated to the engineering part, but it really allows you to appreciate the capabilities JWST.
