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?

    In reality, it’s probably already happened! And the light just hasn’t reached us yet
    Pretty insane to think about that

        1.5 million?
        100,000 years is the much more commonly reported number.

        Still though, should interpret my “probably” as more of a “maybe”, haha

        Probably not, but at most it would be detectable levels. Radiation drops at the square of distance, and there is a lot of distance.
