Welcome to c/news! Please read the Hexbear Code of Conduct and remember... we're all comrades here.

Rules:

-- PLEASE KEEP POST TITLES INFORMATIVE --

-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --

-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --

-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today/ . Twitter screenshots still need to be sourced or they will be removed --

-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--

-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--

-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --

-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

I thought stars twinkle because they're just points, so distortions are enough to move the entire image. Planets are large enough that distortions don't really change the shape or size of the image, they just make it blurry.

Yeah fair enough - both things are subject to atmospheric distortion changing the way they look. I am thinking in the context of ufo-ology though - planets are large enough that distortions in the atmosphere between the viewer and the planet can make the planet look like it's doing stuff - different shadows and warbles on the disc of the planet can look like shit changing form. a star will shift with atmospheric distortion but because it's only a single point of light instead of a disc, it'll appear to move a little in position but there isn't the same intra-object change.

But have you taken in to account my unique mutant trait; Astigmatism!
