Observational Cosmology
Observational cosmology is the field of study within cosmology that focuses on using observational data to study the structure, evolution, and overall properties of the universe. This involves studying the distribution of galaxies, clusters of galaxies, cosmic microwave background radiation, and other celestial objects to gain insights into the origins and development of the universe. Observational cosmologists use a variety of telescopes and detectors to collect data from across the electromagnetic spectrum, including visible light, radio waves, and X-rays. By analyzing this data, they aim to answer fundamental questions about the nature of the universe, such as its age, size, and composition.
