I. What is Radioastronomy? Radioastronomy is a branch of astronomy that involves the study of celestial objects through the observation of radio waves emitted by them. Unlike optical astronomy, which relies on visible light, radioastronomy focuses on the longer wavelengths of the electromagnetic spectrum. This allows astronomers to study objects that are not visible in … Read more
