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?
If you are out somewhere dark enough and look up long enough, you usually see several shooting stars.
Also interesting: some cultures recognize images in nebulae and dark spots in the sky instead of or alongside constellations (eg. Australian indigenous Emu in the Sky)
I just read this article about it https://en.wikipedia.org/wiki/Australian_Aboriginal_astronomy
Thanks!
