It combines a mosaic of millimetre
wavelength images from the Atacama Large Millimeter /
submillimeter Array (ALMA) and the IRAM 30 - metre telescope, shown
in red, with a more familiar infrared view from the HAWK - I instrument on ESO's Very Large Telescope, shown
in blue.

wavelength images from the Atacama Large Millimeter /
submillimeter Array (ALMA) and the IRAM 30 - metre telescope, shown

AzTEC - 3, which is located
in the direction of the constellation Sextans, is what astronomers refer to as a
submillimeter galaxy, since it shines brightly
in that portion of the spectrum, but is remarkably dim at optical and infrared
wavelengths.

The telescope will observe the universe at millimeter and
submillimeter wavelengths, between infrared light and radio waves
in the electromagnetic spectrum.
These are expected to have become rapidly enshrouded
in the dust produced by the first stars; the dust absorbs much of the starlight making the galaxies difficult to see
in the optical wavebands, but these same galaxies shine brightly at millimeter and
submillimeter wavelengths.
This research was presented
in a paper «First Detection of Equatorial Dark Dust Lane
in a Protostellar Disk at
Submillimeter Wavelength,» by Lee et al. to appear
in the journal Science Advances.
ALMA can detect this dust from the early Universe, which is present
in the most distant and ancient galaxies, thanks to
submillimeter wavelengths.
Therefore, the research group targeted molecular line emissions from hydrogen cyanide (HCN), formyl ion (HCO +), and hydrogen sulfide (CS) at millimeter /
submillimeter wavelengths (* 4)
in the galaxy called NGC 1097 (about 50 million light years away) with the ALMA Telescope
in the Atacama Desert
in Chile.
That altitude is above the primary part of the atmosphere that blocks infrared light, which means the telescope can observe at
wavelengths longer than the ones we see
in our Disk Detective WISE data, but shorter than the
submillimeter wavelengths we've observed at with the James Clerk Maxwell Telescope.
