Isn't that amazing?? The two kinds of planets that fascinate me are very common: "hot Jupiters" and "super-Earths". There's quite a bit of selection bias from our observing techniques, but it still seems like these each account for a large fraction of the planets in our galaxy. And nobody expected either of them; they're utterly unlike anything in Sol system.

And if an SF writer had made up a system like TRAPPIST-1 twenty years ago, I would have rolled my eyes at the utter implausibility of it. :)
