摘要：Astronomy is the branch of science concerned with the study of matter in outer
space. The methods of constructing knowledge in astronomy are unlike those
which are used in other fields of scientific inquiry. This is particularly so
because astronomers deal with processes which, many-a-time, cannot be either
explored experimentally or observed given present day technology. In this
paper, Rationalistic tools, like mathematics and logic, and Empirical tools, like
sense observations and quantitative measurements, are discussed as
complementary approaches for constructing astronomical knowledge.
