Tl:dw Hubble is designed to look at objects really far away and isn’t calibrated for Earth or fast enough to track a single spot long enough for good exposure, so the earth would be blurry.
Hubble is old enough that it only has a 1MP camera, so roughly 720p or 1280x720 pixels , so each pixel would represent about 15 feet if you’re generous. A back yard swimming pool would be like 4 pixels, 9 if your parents are rich.
I had to read that, after an earlier thread today claimed Gore did nothing for the climate until after he lost his presidential bid …… that would have been great to post
