While I'm At It, Happy Anniversary, Crab Nebula!

Happy Independence Day to my fellow Americans!

Also, here's an interesting trivia fact from my astronomy wall calendar: the Earth is at aphelion today, meaning it is now at its farthest point from the sun: 152.1 million kilometers.

Only now I'm wondering if it's somehow unpatriotic to use the metric system on Independence Day. Y'know, that's one area in which I wish we were a little less independent.
