submillimeter astronomy

Submillimeter astronomy is a branch of astronomy that studies celestial objects using submillimeter wavelengths of light, which are longer than visible light but shorter than radio waves. It focuses on observing cool gases and dust in space, often associated with star formation and the interstellar medium. Telescopes designed for submillimeter wavelengths can detect these faint signals, revealing the structure and behavior of galaxies, star-forming regions, and even the early universe. This field provides important insights into the formation and evolution of stars and planets, helping us understand the cosmos better.
