The near-infrared region refers to a part of the electromagnetic spectrum that lies just beyond the visible light spectrum, typically ranging from about 700 nanometers to 2500 nanometers. This region is important in various fields, including astronomy, telecommunications, and medical imaging, as it allows for the detection of heat and the analysis of materials. In astronomy, the near-infrared region helps scientists observe celestial objects that are too cool or distant to be seen in visible light. Instruments like the James Webb Space Telescope utilize this range to study the formation of stars and galaxies, providing valuable insights into the universe's evolution.
