Like geolindon said, you can impress people with information about what they are looking at. Like how far away, what it is, how it might be clouds lit up by stars, or how its young stars, etc. Eg the Crab nebula (if you can find it) - it's a star that blew up and you're seeing it as it slowly flies out everywhere. Then go onto how big the universe is, how many stars there are in a galaxy, all that good stuff. People always end up just staring up in a 'wow-ed' state, asking more questions. It's somewhere people dont go very often!
Ends up a discussion about how minute and unimportant this planet is. Then you bust out "On a mote of dust" by Carl Sagan
The above is like therapy.
