Visit the Monsters of the Sky, Namely Supernovae, Pulsars, Quasars and Black Holes

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.
