Spectacular New Views of the Milky Way Released Following Galactic Survey +Video http://bit.ly/24srNKB


A spectacular new 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 at submillimetre wavelengths — between infrared light and radio waves.

This is the sharpest such map yet made, and complements those from recent space-based surveys. 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.

This video comparison shows the central regions of the Milky Way observed in four different wavelength ranges.


The first view shows compact sources of submillimetre radiation detected by APEX as part of the ATLASGAL survey, combined with complementary data from ESA’s Planck satellite, to capture more extended features.


The second view shows the same region as seen in shorter, infrared, wavelengths by NASA’s Spitzer Space Telescope as part of the GLIMPSE survey.
