K-3 Planetarium Lesson: Our Skies
... Ask: What can we see in the sky? Is it different in the daytime/nighttime? What about in the winter vs. summer? Explain that today you are going to talk about astronomy, the study of space and everything in it. Then say you are going to look at some stars. In the summer time there is 1 star visible ...

Core doesn’t go degenerate because next fusion cycle sets in when pressures and temperatures reach high enough level. ...
