Dark Matter
|
|
Nucleus
halo region Galactic disk Spiral arms |
Principal component of the Milky Way
|
|
Our Galaxy, Divided into two categories based on the size of the nucleus relative to the galaxy and the openess of the spiral arms.
|
Spiral Galaxies
|
|
Divided into two categories by how flat they are. (circle) More unified than spirals bc of their lack of gas and dust.
|
Elliptical Galaxies

Red shift= when an object moves towards you, sound/light waves compress and sound/ligh waves stretch when they move away.
|
Edwin Hubble
|
|
Measure distance of stars by using the triangular method
|
Paralax method
|
|
Bigger the star, smaller the wavlength, more energy. Luminosity up, surface up. stars with low temp, not bright
