Up until now, we thought we had this little nook of the universe figured out. Or its size, at least. We were completely wrong, though, because scientists just realized that the arm of the Milky Way in which our solar system resides is about four times larger than previously thought. It’s about 20,000 light years long, which makes it quite a bit shorter (still) than the other major arms of this spiral galaxy. Not exactly huge news, but it’s interesting to know there’s a lot more around us (and closer) than we thought.
