This image of the Milky Way has been released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). 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 â between infrared light and radio waves â and in finer detail than recent space-based surveys. The APEX data, at a wavelength of 0.87 millimetres, shows up in red and the background blue image was imaged at shorter infrared wavelengths by the NASA Spitzer Space Telescope as part of the GLIMPSE survey.Â The fainter extended red structures come from complementary observations made by ESA’sÂ Planck satellite. Note that the far right section of this long and thin image does not include Planck imaging. To fully appreciate this image click on it and zoom and scroll sideways.
