Advancements in Interferometry: Unveiling the Secrets of Stars and Galaxies

The video discusses the evolution of telescopic technology, focusing on the use of interferometry to enhance Earth-based telescopes. Initially, sharp images were only possible from space telescopes like Hubble. However, recent advancements have allowed ground-based telescopes, such as the Very Large Telescope (VLT) in Chile, to achieve similar precision. The VLT uses an array of telescopes working as an interferometer, allowing for ultra-high precision imaging. This technology enables astronomers to study celestial objects in unprecedented detail, potentially leading to the direct observation of exoplanets.
