Much like The Little Prince, the unforgettable protagonist of Antoine de Saint-Exupéry's novel, the program offers a journey through the universe to discover the planets and constellations, analyzing their characteristics and peculiarities. Is it possible that other forms of life exist? And which planets might we one day colonize? Piero Bianucci, a science journalist and astronomy expert, answers these questions. He explains the real climatic conditions of the planets surrounding Earth and takes stock of the promising search for "alien" life. Astrophysicist Edwige Pezzulli also returns with Bianucci. On the front of medical innovation, "Noos" explores how gene therapy allowed Simone, suffering from a rare genetic disease that prevents the production of dopamine, to walk again. Thanks to an innovative procedure at the Policlinico Umberto I in Rome, a harmless virus introduced a healthy copy of the defective gene into his DNA, altering only the dopamine-producing neurons.
