S6E2 Nemesis: The Sun's Evil Twin

Is it possible that a hidden, menacing star is circling our Sun, sending deadly comets into our Solar System every 26 million years? Recent scientific explorations are delving into the far reaches of our Solar System, a space filled with colossal planets and enigmatic planetoids, in search of Nemesis, the Sun's rumored sinister counterpart. This elusive star is believed to be linked to every mass extinction event in Earth's history. To illustrate the concept of Nemesis and the challenges in locating it, experts conduct experiments like igniting a fire on a parched California hillside, racing a NASCAR on an oval track, and juggling flames, emphasizing why uncovering this celestial entity is crucial for the survival of life on Earth.
