Infrared observations refer to the study of objects and phenomena in the universe using infrared light. Infrared light has longer wavelengths than visible light, allowing astronomers to detect heat emitted by objects that may be otherwise invisible in visible light. Infrared observations are essential for studying objects like stars, galaxies, and black holes, as well as for exploring the dust and gas in the interstellar medium. This research area has provided valuable insights into the composition, temperature, and dynamics of celestial objects, contributing to our understanding of the universe's structure and evolution.
