Advancements in Interferometry: Unveiling the Secrets of Stars and Galaxies

The video discusses the evolution of interferometry in astronomy, highlighting its role in enhancing the capabilities of Earth-based telescopes. Initially, sharp images were only possible from space, but recent advancements have allowed ground-based telescopes, like the Very Large Telescope in Chile, to achieve similar results. The introduction of movable auxiliary telescopes has further improved image sharpness, making it possible to observe celestial objects with unprecedented detail. This technology may soon enable the direct observation of planets outside our solar system.

What are the benefits of using multiple telescopes in an array for observations?
