There have been quote a few of these lately, not the least of which is Neil deGrasse Tyson's revamped Cosmos. But this one from Liz at the Royal Observatory Greenwich is pretty good and, to tell the truth, I can't get enough of them. For me, just trying to imagine the size, scale and age of the universe is a bit of a drug (at least I get a little light headed when I really make the effort).
As Douglas Adams said, "space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space."
