Wow
NASA scientists say images from the Webb telescope nearly brought them to tears
Deep field images of the universe, exoplanet atmospheres, and more to be unveiled.

Just a couple more weeks. One of the images will be the atmosphere of an exoplanet.

As we await the first scientific results of JWST, I wanted to post something I read in a book about another important orbital telescope - the Cosmic Background Explorer of the early 1990's.
I recently finished the book The Very First Light by John Mather, who was one of the three principal investigators on the COBE project, and was later awarded the Nobel Prize in Physics for the work his instrument accomplished. Since the COBE project ended, Mather became involved in the development of the JWST as the senior project scientist (the official responsible overall for the scientific aspects of the mission), and had this to say about the goals of the (then-future) project:
"To meet these four challenges - looking as far back in time as we could, learning how galaxies were assembled, seeing inside them, and looking for new planets - would require the biggest, coldest, most sensitive telescope we could possibly imagine. As our small black book 'Next Generation Space Telescope' observed, all of these objectives had to do with how the human species appeared on planet Earth."
This is why JWST is designed the way it is - a gigantic mirror, with instruments attuned to infrared light, so as to best detect the faint and highly-redshifted light of the furthest, furthest galaxies, much older than can be detected by Hubble. That mirror and those instruments will also be able to resolve some much closer, but much fainter objects, as well - rogue planets, failed stars, atmospheres around exoplanets, and so on - that are best seen in infrared or which are too small to see using Hubble or ground-based telescopes. The ability of infrared light to penetrate interstellar dust clouds is yet another benefit.

First Images from the James Webb Space Telescope
The first images from NASA's James Webb Space Telescope, the world’s largest and most powerful space telescope, will demonstrate Webb at its full power, ready to begin its mission to unfold the infrared universe. The first images will be added to this page as they are released.

JWST data released today showed that the telescope is capable of performing chemical analysis of an exoplanet's atmosphere, and those data may be capable of indicating much more.
That's really cool - we're figuring out what planets orbiting other stars are made of, just by looking at them from afar.

Sucks that it has already been damaged by a micrometeoroid, James Webb Space Telescope picture shows noticeable damage from micrometeoroid strike

For its latest images, the Webb telescope looked closer to home

Jupiter images. Pole auroras.

Webb has discovered carbon dioxide around gas giant planet, similar to Saturn.

Maybe I'm misunderstang your sentence structure, but are you saying Saturn has carbon dioxide in its atmosphere? I couldn't find web confirmation of that.

No. Webb has detected CO2 around gas giant in WASP39B system. Planet is similar to Saturn.Maybe I'm misunderstang your sentence structure, but are you saying Saturn has carbon dioxide in its atmosphere? I couldn't find web confirmation of that.

Of course I find this cool...
Jokes aside, the Webb and Juneau missions are making me miss my dark back yard and telescope.

I can see the tinfoil hat club believing that NASA wrote the code and the Webb telescope spreading contrails throughout the galaxy.
