Why did JWST send first images too early?

I believe JWST would take 6 months to send first images, but it send too early i.e on 3 February 2022 Source, why so? Rizosome (talk) 07:24, 22 February 2022 (UTC)[reply]

They need the images to align the mirrors and calibrate everything. It takes six months to finish the alignment so that the telescope can send good-quality science images. What is maybe a bit surprising is that they publish calibration images, but that helps keep the public, including yourself, interested. Incidentally, the website you linked only contains simulated images, not real ones. I've put a real one up here (source is [1]). --Wrongfilter (talk) 07:34, 22 February 2022 (UTC)[reply]

I got the answer from this line: They need the images to align the mirrors and calibrate everything. Rizosome (talk) 04:55, 24 February 2022 (UTC)[reply]
