I believe there’s another even larger optical array type telescope that’s been under construction for several years. It will consist of something like 9 eight meter mirrors
My dream is an asteroid belt array and if I ever become a trillionaire I’ll build it and show you all up. an Ort cloud array would be even better.
I love interferometry! With a space based system, we may someday be able to image mountains on exoplanets (around other stars).
