So if that’s the case, and it can see nearer objects like Jupiter clearly, why can’t it see objects a bit further away like Neptune but can clearly see objects at light years distant?
not buying the whole “oh its bigger (or closer) so that’s why it clearer” argument.
Neptune gets much, much less light from the sun than Jupiter, due to the inverse square law - approximately 3% of the brightness of the sun at Jupiter, and the light is dimmed about 30 times more coming back to Earth, for a total effect of Neptune appearing 1000 times dimmer than Jupiter when viewed from Earth (not even counting the smaller size of Neptune.
The Hubble can attempt to compensate by making a longer exposure, but that will cause blurring due to Neptune’s rotation.
It is no surprise that Neptune appears nearly featureless in photos from Hubble.
Remember when they first put it up? It couldn’t see at all.
