Exam 2 Astronomy 104 Fall 2007

Format of the exam

In general the format of this exam will be  similar to the first exam. One new feature is the identification of types of objects from images (see below). 

Image identification: For part of this you will be asked to identify different types of objects such as: emission nebula, reflection nebula, dark nebular, open cluster, globular cluster, and planetary nebula. Look here for examples of the different types of objects.   Do not worry about "planetary nebula" that are given in the example images.

Note that there will be a section with questions about stars on the HR diagram. (This is part of what I listed as "matching")
