The moon Pan is fantastic. I had never seen that one before. No idea how that could have formed. 

  Do the flat-earthers think the other planets are flat too?

As a kid, the likes of Pluto were the odd, little planet relegated to a few lines at the back of an astronomy book. We knew more about the likes of Saturn (and various moons in our solar system), but not as much as we know now.

And although terms like "multiverse" and "dark energy" may well predate all of our births, I certainly don't recall hearing them used when I was a kid (outside comics, of course).

Feel privileged to be alive now - at a time when I can follow status reports about Pluto on Twitter or be privy to exciting discoveries.

I don't know if HORIZON airs outside the UK, or exactly whether non-UK people can access BBC iPlayer, but do keep an eye on HORIZON as it frequently has space-themed episodes.
