For instance, the ESA has many options for most of their pictures, one of them being a 122.4mb TIFF. Then there will be all the aggregator sites that host the same image at lower quality…
As for increasing the quality; it’s really difficult to do. IIRC there was a group of people that hand edited each and every frame of the original Star Wars trilogy from VHS quality to 4k. It took years and they almost ran out of money before finishing the Empire Strikes Back. As much as I hate how AI is being shoved down everyone’s throats these days, this is one of those things that it is/would be good at (when applied properly) and was actually meant for; trawling through massive amounts of data and making connections.
It really depends on what your sources are.
