The Raleigh criteria for 1km resolution at 20ly requires an interferometer with a baseline of 120,000km. That’s about a third of the way to The Moon or 10x the diameter for The Earth.
How far away is such technology?
For 1000km resolution the requirement is three orders of magnitude smaller, or ~120km. Could such a device be terrestrial?
