is it possible to see the flag on the moon with a large telescope?

Answer 1

It is not possible to see any man-made object left on the moon with any already existing telescope from Earth or near-Earth Orbit....the objects are just too small and too far away.
Governed by certain laws of physics, telescopes of a given size can only see objects of a certain minimum angular size or larger. The angular size of any/all man-made object on the moon as seen from the Earth is just way too small to see, even when being very generous with size and distance estimations.
So, in short, no, you cannot see the flag on the moon with a large telescope.

Answer 2

Diffraction effects due to the wave nature of light imposes a lower limit on the detail that a telescope of a given size can see. Basically, the larger the diameter of the telescope mirror, the smaller the detail it can see. Calculations show that to see detail as small as 1 foot at the distance of the Moon would require a telescope with a main mirror almost half a mile wide. So, no, it is not possible.

Answer 3

No...we can't. Every telescope has its own resolving power... even though we build a very large telescope, atmospheric blurring will reduce its efficiency.

That's why we build Hubble space telescope...to reduce/get rid of atmospheric blurring shortcomings.

But even Hubble space telescope can't see the flag on the moon,because its resolving power is just 80 meters across (meaning the object on the moon must be 80 meters or more to be clearly visible and distinguish by hubble)

Answer 4

Not with large telescope but with power full one.
But there should be certain favarable conditions.

Answer 5

With one in an obsrvatory, probably. You'd need to target it very precisely, though.

Answer 6

From earth ?

Answer 7

No

Answer 8

why not?
