Removed the part about L2 being in Earth's umbra. Although this is true, the JWST is not actually ''at'' L2; it revolves around L2, specifically to avoid being in the Earth's umbra (and the moon's) and therefore avoid changes in temperature.

Does anyone know whether they use [https://ds9.si.edu/doc/user/rgb/index.html SAOImageDS9] or [https://docs.astropy.org/en/stable/visualization/rgb.html Astropy] to make full color images? Both are listed under [https://www.stsci.edu/jwst/science-execution/data-analysis-toolbox post-pipeline tools.] General instructions are in [https://arxiv.org/pdf/2001.02618.pdf this paper] but it's not a software tutorial, and it doesn't mention un-redshifting very distant objects like in [https://www.youtube.com/watch?v=sNJR3lenz1I&t=293s Dr. Becky's video] (and which they didn't do completely for the deep field because the lensed galaxies were actually red.)

:Can we use the published image [https://www.stsci.edu/jwst/phase2-public/2736.pdf data] files to produce a {{w|SMACS J0723.3–7327|SMACS 0723}} image with only the far-redshifted, lensed objects? [[Special:Contributions/172.70.211.36|172.70.211.36]] 16:01, 14 July 2022 (UTC)
::There is a tutorial at https://www.galactic-hunter.com/post/jwst-data by a guy who uses PixInsight, which unlike DS9 and Astropy is commercial (€230) but a anyone can use it free for 45 days. I think the instructions for what you want to do are at https://pixinsight.com/tutorials/PCC/index.html and the data is [https://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html?searchQuery=%7B%22service%22%3A%22JWSTFILTERED%22%2C%22inputText%22%3A%5B%7B%22paramName%22%3A%22targname%22%2C%22niceName%22%3A%22targname%22%2C%22values%22%3A%5B%22SMACS%20J0723.3-7327%22%5D%2C%22valString%22%3A%22SMACS%20J0723.3-7327%22%2C%22isDate%22%3Afalse%2C%22facetType%22%3A%22discrete%22%2C%22displayString%22%3A%22SMACS%20J0723.3-7327%22%7D%5D%2C%22position%22%3A%22undefined%2C%20undefined%2C%20undefined%22%2C%22paramsService%22%3A%22Mast.Jwst.Filtered.Miri%22%2C%22title%22%3A%22JWST%3A%20%20Advanced%20Search%201%22%2C%22tooltip%22%3A%22SMACS%20J0723.3-7327%3B%20%22%2C%22columns%22%3A%22*%22%7D here] for SMACS 0723.

When discussing biosignatures of exoplanets, should we draw the distinction between ozone and water? [[Special:Contributions/162.158.106.113|162.158.106.113]] 11:58, 14 July 2022 (UTC)
