This is a little more technical, but since you got a slightly different answer as well, a "master's degree" is considered a common noun, as such it is not capitalized, while a "Master of Science", or a "Master of Arts in Literature", are considered proper nouns, so they are capitalized.

Yes, Thanks a lot, Sarah!

A master's degree is a 2nd college degree for a student. It's for a college graduate after they already have a 4 year bachelor's degree. It typically takes about 2 years, and consists of the courses portion of a doctorate degree, and a master's thesis. The master's thesis is a longish paper about some topic in the field, but unlike a doctoral thesis, it is not original research and is not evaluated on making an original contribution to the field. Both master's and doctorate degrees are considered graduate degrees. Meaning they are degrees for students that have already graduated from college. As such, they are called graduate students, or grad students. College in the US: 4 years bachelors (also called undergraduate degree) 2 additional years for a master's degree -or- 5-6 additional years for a doctorate degree You typically wouldn't get a masters degree and a doctorate in the same subject. Sometimes a student pursuing a doctorate degree that doesn't complete it will receive a master's degree instead. "master's degree" does not need capitalized.

It's short for Master of Arts or Master of Science. So I have a Master's degree is the correct form. I am studying for a Master's degree in Astronomy would be correct. Then you would be a Master of Astronomy. Is that any clearer?
