Slide 1
- Fisheye Milky Way. Notice Thin on one side bulge towards the other
  i.e. towards Constellation Sagittarius

Slide 2
- Powers of ten. Scale 100 Ly see map of star nearby

Slide 3

- Powers of ten. Scale 1000 Ly evidence of spiral structure
  i.e. voids of stars and nebulae

Slide 4
- Powers of ten. Scale 10 000 Ly what we assume our Galaxy to look like
along with satellite galaxies

Slide 5
- Observational evidence via mapping hydrogen as proof of spiral structure.

Slide 6
- Picture of Milky Way. It is made up of more than stars such as dust (seen
in the dust lanes) and nebulae (seen in red)
Hubble Deep Field

Slide 7
- Several planetary nebulae. Not the spherical shape and the bright object
in the center which is a dieing star. Will talk about that in the Hertzsprung Russell lab.

Slide 8
- Globular clusters. Interesting because they are some of the oldest known
objects ~ 10 to 15 billion years old. Distribution are centered around the
center of the Milky Way i.e. the bulgy part of the galaxy shown in the first slide.

Slide 9
- Pictures of other galaxies...where do they reside on the map??
