Last night I was at the Lowell Observatory in Flagstaff, Arizona.
I saw the telescope--still in the same wood-lined observatory--
that Clyde Tombaugh used to discover Pluto.
Pretty wondrous, actually.
So today, Wonder No. 4, the galaxy of moons, stars, and planets.
We'll start with tiny little Pluto (see the arrow):
And thousands of twinkling lights from stars in the night sky:
Looking up into the night sky
allows us see that we are part of something a whole lot bigger.
And that's pretty wonderful.
