      We don’t know! Every time we find a new way of looking out into the universe we discover new and unexpected things. We don’t even know what makes up most of the mass of the universe.

      We don’t know how many galaxies are in space for sure, or even how many universes we have! I think the answer is more than you could ever imagine. Mind-boggling!

      So so many! And probably tons of stuff we haven’t even discovered yet, and most likely things which we don’t even have on earth. They have found some pretty cool planets, like a planet completely made out of diamond (55 Cancri e) or a planet of burning ice (Gliese 436 b). That’s pretty cool!
