Millimeter Astronomy

Millimeter astronomy studies celestial objects by observing microwave radiation at millimeter wavelengths, roughly from 1 to 10 millimeters. This method allows astronomers to detect cold regions in space, such as molecular clouds where stars form, and study the composition of cosmic dust and gas. Because millimeter waves can penetrate dust clouds that obscure visible light, this technique reveals hidden structures and processes in the universe. It helps improve our understanding of star formation, galaxy evolution, and the cosmic environment, providing a critical window into the otherwise unseen universe.
