Astronomy is presently defined as the study of all the matter and energy in the universe, although some restrict the field to what is beyond the earth's atmosphere. Astronomy and astrophysics are closely intertwined but may be distinguished by regarding the former as primarily observational and the latter as analytical, i.e., interpreting the observations by applying knowledge gained in the study of physics and chemistry.
