Look up VLBI, very long baseline interferometry. While the image made from a few distant apertures (say, spanning a circle of 7000 miles diameter, e.g. the Earth) will have large diffraction artifacts that would be absent in the image of an image taken with an actual 7000 mile diameter telescope, the former image will nevertheless have features that are comparable sharp to those in the latter image. These sharp features can be extracted from the image, with the result that a sharp image can be constructed as if an actual 7,000 mile diameter telescope had been used.
so the telescope is to really earth sized, but the images it can see are?
I’ll look it up more tomorrow. thanks.
Where is the pic?
