Stars

Today we talked about stars - from how they form up until how they die. We also discussed the different properties on how stars are categorized.

The assignment today was the workbook pages 317-318.

I neglected to add the vocabulary for this section in my previous post but it is as follows:

cosmology, big bang, doppler red shift, dark matter, dark energy, protostar, nuclear fusion, apparent magnitude, absolute magnitude, luminosity, solar mass, main sequence, solar system, galaxy, universe, astronomical unit
