Galaxies This lesson deals with important topics relating to galaxies. Each of these topics represents a great body of knowledge and areas of interest to research.
Galaxies. The Hubble Tuning-Fork Diagram. This is the traditional scheme for classifying galaxies:. Elliptical Galaxies.
Galaxies. Chapter 20. Galaxy Classification. In 1924, Edwin Hubble divided galaxies into different “ classes ” based on their appearance. Why begin here? Hubble classification serves as the basic language of the field.
Galaxies . Chapter Twenty-Six. Note…. I posted as a way to help you a list of topics covered in Exam 2 (they are all in my class notes).The link is at: http://physics.gmu.edu/~mopher/ASTR113/topics_exam2.html. Guiding Questions. How did astronomers first discover other galaxies?
Galaxies. Milky Way . A galaxy is a large, isolated system of stars held together by gravitational forces. Our Solar System is located in the Milky Way Galaxy. Structure of the Milky Way. The Milky Way has a disk -like shape with a central bulge. Structure of the Milky Way.
GALAXIES. From: Jim Lochner, USRA & NASA/GSFC. What is a Galaxy ?. Solar System. Distance from Earth to Sun = 93,000,000 miles = 8 light-minutes. Size of Solar System = 5.5 light-hours. What is a Galaxy?. Stellar Region. Sun (solar system too small to be
