Web Seminar

I did not attend the seminar, but I did go through the PowerPoint and a few sites. Our universe amazes me more every day. The seminar discussed stars. I understood most of the information given. I knew that stars were mostly made of Hydrogen and Helium. I did not remember that the most important factor in how a star evolves and dies is based on its’ initial mass. To think that clouds can condense enough to form a star is a hard point to wrap you mind around. The seminar discussed high mass stars and how they are brighter and have shorter lives then low mass stars.(High=Rigel; Low=Sun) The star classification was also something new to me since I really only found out about it about a month ago. I enjoyed trying to figure out the mystery star, which I think was composed of Iron and Magnesium. I was wondering about a neutron star and how it was formed since I cannot, for the life of me, remember. I thought that the seminar must have been very enlightening and very useful in information for teaching students about stars.
