We have long known that the dinosaurs were killed by a catastrophic comet impact with the Earth’s surface but what if there was some foul play afoot? Astronomers have discovered that our sun may have been born with a twin, and an evil one, at that. One hypothesis states that every 27 million years, the evil twin, aptly dubbed Nemesis, returns to wreck havoc on the solar system. They believe that the star lobs a few meteors in our direction as it makes its may through the outer limits of the solar system.
Research has lead scientists to believe that most stars are born with at least one sibling. According to UC Berkeley astronomer Steven Stahler, “We ran a series of statistical models to see if we could account for the relative populations of young single stars and binaries of all separations in the Perseus molecular cloud, and the only model that could reproduce the data was one in which all stars form initially as wide binaries.”
