I love astronomy....ever since I was a child playing with a cheapie, three tube boy scout pirate telescope back in the early 80s. Seeing the Sea of Tranquility on the moon; albeit poorly was pretty exciting.
Further, it always felt like what I thought the ocean would be like (as i didn't grow up near). Observing the edge of a body of water that was so hard to fathom of size; but space being even larger.
Simple yes but so interesting to think about:
The speed of light is finite whereas we know how long it takes optical light to travel an unencumbered distance.
Our closest star in the night sky (other than the sun), proxima centauri resides roughly 4.3 light years from earth. Meaning, what we see now is a twinkle from four and a third years ago.
Cassiopeia resides 16,308 light years away; the Andromeda galaxy is 2.5 million light years away. Both can be seen with the naked eye.
Summary....if you really want to look deep into our past....just look up after dark.
Its just really interesting to wrap your head around....or at least it is for me.
