It's easy to think that astronomy and astrophysics are just synonyms, but they have several key differences. Astronomy is the study of stars and planets, galaxies, and other matter that can be seen from Earth. Astrophysics is the study of the physical nature of such objects that can't be observed from Earth with visible light, such as black holes and dark matter: According to Dr. Mohamad Abbas, the field of astronomy has been around longer. Astronomy is a branch of physics, a word that refers to the measurable properties of matter at all levels. Astrophysics isn't limited to observations made from Earth; it also involves observations made from outer space by telescopes such as NASA's Hubble Space Telescope and the European Space Agency's Herschel Space Observatory. Both astronomy and astrophysics involve several subdisciplines that represent different ways of looking at objects in space. These include observational astronomy, which involves observation and cate
