|In the previous lab we learned about the difference in the distribution of globular and open star clusters. This difference in distribution tells us something about the Milky Way Galaxy and its surroundings. The graphics (left) provide a bird's-eye-view of what our Galaxy would look like if we could step outside of it.
We live in the disk, which has spiral structure. Note the distribution of globular clusters. They are found outside the disk of the galaxy.
The open clusters are also in the disk, as you discovered in the last lab.
In the previous lab we learned about the difference in the distribution of globular and open star clusters. In this lab we will travel beyond the Milky Way galaxy to some of our galaxy's nearest neighbors. We will first learn how to measure distances to other galaxies and then we will learn about some of their interesting properties.
