This lack of moisture, combined with the thin atmosphere at high altitude, offers ideal conditions for observing the cosmos at the still mysterious millimetre and submillimetre wavelengths which are emitted by cooler objects.
The antennas operate at wavelengths between 0.00035 and 10 millimetres: that is, from submillimetre wavelengths to the beginning of the microwave range.
At these wavelengths, astronomers can peer at the disks of gas and dust around newborn stars, see into star - forming clouds, and observe early galaxies that are bright in submillimetre wavelengths but obscured by dust in optical light.
Mattia Negrello of the Open University in Milton Keynes, UK, and colleagues found the galaxies by the glow of their heat at submillimetre wavelengths.
The two scientists observed Geminga using the James Clerk Maxwell Telescope (JCMT), which operates at submillimetre wavelengths, sited on Hawaii.
This experiment detects radiation of millimetre and submillimetre wavelengths, a different range from COBE, providing further evidence that the ripples are primordial, and are not just background emission from our own Galaxy (see Figure 3).
The APEX telescope in Chile has mapped the full area of the Galactic Plane visible from the southern hemisphere for the first time at submillimetre wavelengths — between infrared light and radio waves — and in finer detail than recent space - based surveys.
«Only a few gravitationally lensed galaxies have been found before at these submillimetre wavelengths, but now SPT and ALMA have uncovered dozens of them.»
The wavelength of the light emitted by these remote galaxies is «stretched» as it travels toward us, because the Universe is expanding: what starts as infrared light eventually reaches Earth with millimetre or submillimetre wavelengths.
