Journey into the Cosmos

Today's imaginary journey into the cosmos targets Saturn, Uranus, Neptune, and Pluto, mysterious outer planets of the solar system millions of kilometers away from Earth. The NOOS astronauts visit Titan, traveling across its methane lakes in a special overcraft, and Miranda, Uranus's icy moon, carved by fractures and ravines. Their next stop, at the edge of the solar system, are the geysers of Triton and the Hoort Cloud: a cluster of approximately one hundred billion comets that seems to envelop the solar system like a shell. Alberto Angela is joining us from NASA's Exobiology Research Center, at El Tatio, 4,300 meters above sea level in the Andes, and from the Institute of Nuclear Physics in Frascati, Rome (where experiments are being conducted to reach absolute zero).

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.

The Noos spaceship continues its adventure in space: from one end of the universe to the other to observe those stars with characteristics so surprising and unusual that they've been nicknamed the monsters of space. Today's episode features encounters with vampire stars, whose extremely strong gravitational pull sucks matter from nearby stars until they disintegrate; stellar twins, born from the same gas cloud; black holes that swallow everything that passes by; and supernovae, stars collapsed by matter weighing thousands of tons per cubic millimeter. Alberto Angela joins us from Chaco Canyon, a city abandoned hundreds of years ago where rock carvings depict the explosion of a supernova; and from Socoro, also in New Mexico, one of the world's largest astronomical observatories; before explaining Einstein's theory of relativity from the National Institute for Nuclear Physics in Frascati.

The Noos spaceship embarks on a surprising journey into the future today: reporter AstroPiero gives us the opportunity to discover what some of NASA's projects might look like if they were realized. First and foremost, a lunar base: a home on the moon to house astronauts and scientific equipment. But there's also another point in space, just a few hours' travel from Earth, where large orbiting stations could be built, complete with living quarters and laboratories. From these, spacecraft could be launched to reach satellites or devices in orbit, such as massive solar power plants that convert solar energy into electricity. And there are also space colonies, designed to house 2 million people: enormous cylinders 25 kilometers long and 6 kilometers in diameter that rotate, thus creating artificial gravity within themselves.

In the final episode of his program, Piero Angela, aboard the spaceship Noos, speeds through the billions of stars in our galaxy toward a distant, imaginary planet whose characteristics allow for the formation of life, albeit primordial. But is it really possible that other forms of life exist in the cosmos? Many scientists even believe it is probable. In the second part of the episode, Piero Angela takes us on another, equally captivating journey: a behind-the-scenes look at the program, revealing all the tricks that made the special effects possible: the flybys and landings on planets and satellites, the zero gravity inside and outside the spaceship, the three-dimensional effects of sandstorms, geygers, and lava flows, and finally, the ride through stars and galaxies outside our solar system.
