Unbelievably Large Telescopes On the Moon?
Matt_dk writes "A team of internationally renowned astronomers and opticians may have found a way to make "unbelievably large" telescopes on the Moon.
'It's so simple,' says Ermanno F. Borra, physics professor at the Optics Laboratory of Laval University in Quebec, Canada. 'Isaac Newton knew that any liquid, if put into a shallow container and set spinning, naturally assumes a parabolic shape, the same shape needed by a telescope mirror to bring starlight to a focus. This could be the key to making a giant lunar observatory.'"
We have. This "news" is literally decades old.

Stick at relay satellite at the Earth-Moon L4 or L5. That means the telescope couldn't be exactly opposite Earth, but if there's still a lot of room where it's shielded from Earth but still in view of L4 or L5.
...at the sun's gravitational focus. You'd be able to resolve a planet halfway across the galaxy.
