Why can't we build a huge stationary optical telescope inside a depression similar to the FAST radio telescope?
So first we'll have to find a natural depression or we should create one. I understand you can only see a single portion of the sky since it can't be moved, so my money is on creating an artificial ...

What causes "North-South ambiguity" when doppler radar imaging a planet surface equator?
I'm having a hard time understanding why there would be this ambiguity. Also, why would this be not the case if the planet was viewed pole on?
Edit: "North South ambiguity" is a term used in ...
