The image was completed by the APEX telescope in Chile.
The telescope “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,” according to the European Southern Observatory.
“The pioneering 12-metre APEX telescope allows astronomers to study the cold Universe: gas and dust only a few tens of degrees above absolute zero.”
The new map covers an area of the sky 140 degrees long and 3 degrees wide.
“ATLASGAL has allowed us to have a new and transformational look at the dense interstellar medium of our own galaxy, the Milky Way,” said Leonardo Testi from the observatory in a statement.
