Web Seminar

I wish I could have experienced the actual web seminar but I wasn’t able to due to work. But I certainly still did learn a great deal from seeing the presentation and looking through the PowerPoint. Some things I learned are that stars are primarily made up of mostly Hydrogen which makes them glowing balls of gas. Mass is the main factor that plays a part in how a star is formed and eventually dies. I guess I have never thought about a star “dying” before. Really it means that the star died in an energetic explosion, if it is high mass, engulf planets losing outer layers and becoming a white dwarf if it is medium mass, or just puffing out and becoming a white dwarfs if it is small mass. Some more information I learned is that high mass stars are bright and have short lives where as low mass stars are less bright and have much longer lives. I find this really interesting because though a high mass star’s life is considered short, it is still hundreds of millions of years long! I know I don’t know a great deal about astronomy, but this seminar taught me some fun facts about stars. They are great big balls of gas that live millions-billions of years fully of hydrogen and helium.
