BBC : The European Southern Observatory (ESO) has released the complete set of data from the Apex Telescope Large Area Survey of the Galaxy (ATLASGAL) project to map the Milky Way’s gas. The project used the Large Bolometer Camera attached to the Atacama Pathfinder Experiment, a 12 m telescope in Chile designed to measure small temperature variations within the galaxy’s dense gas clouds. The data set covers a region of the sky 140° long and 3° wide, four times as large as the area covered by a 2009 partial data release. ESO also generated an image of the Milky Way that combines the ATLASGAL data with measurements at different wavelengths collected by the Planck and Spitzer space telescopes.
