Well, the intriguing possibilities affecting the likelihood of a mysterious companion in our Solar System continue to blossom. First, the actions of comets suggested that there may be a large “Planet X” named Tyche beyond the Oort Cloud. Then, we discovered planets around distant stars with highly elliptical, highly inclined orbits, giving us more potential […]

Researchers at the University of Kansas and the Smithsonian Institute have performed one of the most extensive analyses of Earth’s past extinction patterns to date. So, what did researchers Adrian Melott and Richard Bambach conclude? Planet X cannot exist. Planet X, also known as Nemesis, is a proposed “dark” (i.e. dim) companion star to the […]

Recent observations of the nearby (44 light-years away) multi-planet star system Upsilon Andromedae have kindled in my mind an intriguing question: Namely, can our own solar system have one or perhaps many “Planet Xs” hiding in oblique orbits? Allow me to explain. It has been known for quite some time that the Upsilon Andromedae star […]

Our solar system may have just gotten a lot more interesting. Researchers studying the orbits of comets at the University of Louisiana have found a problem. -They’ve discovered an inconsistency with how comets are spread out compared to what you would expect under ordinary galactic conditions. In an article recently submitted to the journal Icarus, […]
