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?

    What they’re really saying is that the dominant wavelength our sun emits is around 500 nm. Which by definition is green light. Astronomers also call everything heavier than helium a metal, which isn’t true but that’s how they work.
