While camping, I noticed that if you look long enough at almost any star, you start seeing some tiny, subtle colors in that star. Even crazier, they sometimes flicker between more colors. In my case orange, blue and something like cyan.
Besides constellations, what else could you observe regarding starts, with the naked eye?
Over the year, the starts shift position. They rise about 4 minutes earlier every day. So some stars you can see now will be invisible for you in a few months.
