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.
Discovery made possible by a leap
in submillimetre radio astronomy technology, comparable to viewing videos instead of photos.
[2] The Atacama Large Millimeter / submillimeter Array (ALMA), operated in part by ESO, observes
in submillimetre and millimetre light and is ideal for the study of such very young stars in molecular clouds.
As they are opaque to visible light it is difficult for astronomers to observe their inner workings, and so other tools are needed to unveil their secrets — observations in the infrared or
in the submillimetre parts of the spectrum, for example, where the dust clouds, only a few degrees over absolute zero, appear bright.

The protostar is still quite cool — about -250 degrees Celsius — and shines only
in long - wavelength
submillimetre light [2].
This radiation was stretched to longer wavelengths as space itself expanded, and by the time it reached Earth — and Herschel — it was
in the far - infrared and
submillimetre range.
«If we succeed
in building the world's first terahertz imager operating
in these frequencies, it would represent a true breakthrough for
submillimetre - wave remote sensing from space.
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.
Even
in the Early Science phase, when the new observations were made, ALMA greatly outperformed other
submillimetre observatories.
SCUBA - 2 will keep the JCMT at the forefront of
submillimetre astronomy, complementing the Submillimeter Array on Mauna Kea and forthcoming telescopes such as the Atacama Large Millimeter Array
in Chile.
Deadline: Monday 16 October 2017 (23:59:59 UTC) APEX, the Atacama Pathfinder EXperiment, is a 12 m diameter
submillimetre telescope at 5100 m altitude on Llano Chajnantor
in Chile.
With ALMA's unprecedented resolution and sensitivity, the research team was able to image the far more abundant cold dust, which glows brightly
in millimetre and
submillimetre light.
The JCMT is the largest single - dish telescope
in the world dedicated to detecting
submillimetre radiation.
Workshop on millimetre and
submillimetre astronomy
in Italy», organised from the Italian node of the European ALMA Regional Centre
in Bologna from 7 - 10 November 2017.
