WebWhen stars die, their fate is determined by how massive they were in life. Stars like our Sun leave behind white dwarfs: Earth-size remnants of the original star’s core. More massive stars explode as supernovas, while their cores collapse into neutron stars: ultra-dense, fast-spinning spheres made of the same ingredients as the nucleus of an atom. WebDubbed "Nemesis" (after the Greek goddess of retribution), the companion star through its gravitational pull unleashes a furious storm of comets into the inner solar system that lasts anywhere from 100,000 years to two million years. Of the billions of comets sent swarming toward the sun, several strike the Earth, triggering a nightmarish ...
