1.3mm Observation

(observation frequency useful for detecting dust)

1.3mm Observation of Electromagnetic Radiation (EMR) is useful for detecting how much cold Cosmic Dust is somewhere. The thermal continuum of cold dust produces considerable 1.3mm signal with few enough other sources to make it useful when looking at dust clouds and planetary disks. Dust is optically thin at this Wavelength so the signal corresponds to the mass of the dust cloud. Submillimeter Array (SMA) and other similar telescopes image and survey at this wavelength.
