I've noticed NASA's James Webb Space Telescope is intended to orbit around the second Legrange point L2 once it's launched, which is the same orbit as ESA's Herschel sub-millimetre telescope currently holds - is the intention to have them both orbiting at the same point? If so, how does that work?!

Why we are using hubble telescope so near to the earth ? And if we could moved it to far end of our solar system like voiger spacecraft so we can see more deeper in space !

This one's making my brain hurt.

Given the enormity of galactic bodies, doesn't it follow that (unless we're lucky enough to regard a galaxy at an exact right angle to its plane of rotation) the light from its more distant edge has taken aeons longer to reach us than that from its nearer edge?

Consequently, doesn't it follow that the "flat" images our telescopes are seeing are hopelessly distorted versions of what's really there?

Why can't one of our space telescopes, capable of seeing galaxies many light years away, be pointed at the site of the moon landings where one can assume there are some remnants from the visits.

Would this definitely prove to any sceptics that humans landed on the moon? It would be a nice way to celebrate the 40th anniversary of the first landing.
