At what wavelengths have astronomers mapped and studied the distribution of giant molecular clouds in space?

Question

Quizplus · Accepted Answer

Astronomers have mapped and studied the distribution of giant molecular clouds using radio telescopes at millimeter wavelengths, as these wavelengths are able to penetrate the thick clouds and detect the emission from molecules within the clouds. This allows astronomers to study the structure and composition of these clouds, which are important sites of star formation.
