Stars

1. Q: How are constellations useful to astronomers? How many stars are not part of any constellation? A: Constellations can be useful to astronomers because they can be used when finding positions in the sky. In scientific terms constellations are now referred to as patches of sky. Every star is part of one scientific constellation or another.


 * //Jason, I am a fool. I forgot to start the study of stars. It is tough doing it all online! In you text there is a very nice illustration showing the typical life cycle of a star like ours. Could you describe it? (You can do this with pics or words. Or a combo)//**

They first come out of a stellar nursery, then they turn into the form that our star is now in, then they change into a red giant. From there they turn into a planetary nebula, then into a white dwarf, and finally a black dwarf.
