astronomy
[U] Uncountable
pl: nullpast: nullpp: nulling: nullcomp: nullsup: null
This term describes a rigorous scientific discipline based on physics and mathematics. It carries a connotation of vastness and objective observation, focusing on the mechanics of the cosmos rather than the interpretation of destiny. It is distinct from astrology, which is a pseudoscience. While astronomy seeks to explain the laws of the universe through evidence, astrology claims to predict human affairs based on planetary positions. Using astronomy in a professional context implies academic rigor and empirical research.
Used as a general field of study or a branch of science, such as when saying astronomy is a difficult subject.
