Seeing the universe through more than just human eyes
In short: Observational astronomy is the study of celestial bodies using different regions of the electromagnetic spectrum. This video explains how scientists capture information from space by looking beyond visible light to various types of radiation.
The primary source of data regarding objects in space is electromagnetic radiation, which includes visible light. However, observational astronomy is categorized based on which specific region of the spectrum is being targeted for study.
Because Earth's atmosphere acts as a filter, certain types of radiation can only be detected from high altitudes or from locations outside our atmosphere entirely. Understanding these limitations helps astronomers determine where to place instruments to capture the most accurate data.
