In a paper to be published in Astronomy & Astrophysics, researchers say they have found that "Tau Ceti, one of the closest and most Sun-like stars, may host five planets, including one in the star's habitable zone."
Very interesting quote from Steve Vogt, a professor of astronomy and astrophysics at UC Santa Cruz, who is one of the paper's authors:
"We are now beginning to understand that nature seems to overwhelmingly prefer systems that have multiple planets with orbits of less than 100 days. This is quite unlike our own solar system, where there is nothing with an orbit inside that of Mercury. So our solar system is, in some sense, a bit of a freak and not the most typical kind of system that Nature cooks up."
This is, among other things, a good reminder that the local patterns you are familiar with are not necessarily representative of the broader world (or universe!). It is easy, and tempting, to assume that the politics/family dynamics/fill-in-the-blank that you see around you daily is common elsewhere; but often, it's simply not.
