>I wonder what they imagined we’d do with them

Before / After

the sky is changing constantly, just on scales we don't have the patience to witness. it's not unlike those before/after hurricane/tornado/fire/flood satellite images.

there's also the parallax tests where you image the sky, and then image the same thing in 6 months so that the earth has moved ~halfway around its orbit. overlay the 2 images, and you can see slight shifts.

also, now, the AI is being used to find things mere mortals have missed. several comets have been found using older images stacked to see things moving in a timelapse fashion. they've been used to find supernovae and other things where there's something brighter in one image, but was not that bright in previous images, and not so bright in subsequent images.
