Science 90 - Jan 12

Today we finished out notes on stellar evolution with a look at pulsars and black holes, the possible endpoints for massive stars.  We then learned about galaxies and what galaxies are.  There are 4 different types of galaxies.  As well, notes were given on the definition of a quasar and the mystery of dark matter.  Students spent the remainder of class working on the assignment given at the end of stellar evolution on Slide 53.  This is due tomorrow. There was an assignment at the end of galaxies but we are not going to do it.  The notes we took today we on slides 51-58.  Tomorrow we will learn about the universe as well as some information on our search for extra-terrestrial life.
