Lab 9: Cosmic Distributions

Galactic Distributions

Distributions may appear different depending on where we are located with respect to an object.

Isotropic Distribution: Objects appear [random] (without particular order) to an observer. The object is most likely [NOT IN] our galaxy.

Anisotropic Distribution: Objects tend to be [clustered] in a particular region. The object is likely [IN] our galaxy.

1. Halo: Occurs when the objects surround a [point] at a distance away from the observer.
2. Disk: Distribution will be flat (in a disk). Occurs when the objects surround the [observer's view] in a plane-like region.

Star Clusters:

Open Clusters (aka: galactic) are found in the [disk] of the Milky Way where there is more gas and dust and typically have bluer stars.

Globular Clusters are found in the [halo] of the Milky Way and typically have redder stars.
