Interferometry baselines turn separated dishes into one sharp eye
Radio and optical interferometers combine light waves from telescopes kilometers — or continents — apart so the effective resolution matches a dish as wide as the longest baseline.
Correlators preserve phase information; more baselines fill the aperture plane and sharpen the reconstructed image. The technique underpins arrays from regional networks to Earth-sized virtual dishes.
Distance is aperture. Interferometry proves teamwork can out-resolve any single mirror on the ground.
