Space!
I did the first workout in a Couch to 5k program tonight. It felt awesome. It was a gorgeous, clear, starry night, and I could see Jupiter shining brightly in the east, so when I got home I took my telescope outside and had a look. I could see three of its moons, and two clear cloud bands. Four hours later I checked it again and could see 4 moons. I know from this that the moon that appeared in the four hour interval was Io, which was just passing across Jupiter's face earlier in the night. It's odd to look at a tiny point of light in my telescope and think, "That's the most volcanically active body in the solar system,". Since I got my telescope Jupiter is the only planet that's been easily visible -- Mars sets in the west just after the sun these days, and Saturn rises in the east just before the sun. Venus is visible too, but it's just a featureless ball of light through the 'scope. I don't know enough about astronomy yet to know (or really care) much about its phases.
