The Noos spacecraft today reaches one of the eight hundred comets in the solar system, continuing through the Milky Way toward Alpha Centauri, the brightest and closest star to Earth, about eighty thousand kilometers away. Next stop are the Magellanic Clouds and the Andromeda Galaxy, surrounded by a myriad of smaller galaxies scattered across the cosmos like archipelagos in an ocean . Correspondent Alberto Angela connects first from the Chilean coast to explain the role comets played in Earth's evolution from a location reminiscent of primitive Earth, then from ESO's La Silla Observatory, also in Chile. From Mauna Kea, in the Hawaiian Islands, he then introduces us to the famous twin domes KEK1 and KEK2, equipped with state-of-the-art telescopes.
