Mostly Mute Monday: New Map Of The Milky Way Is Complete (Synopsis)

"True realism consists in revealing the surprising things which habit keeps covered and prevents us from seeing." -Jean Cocteau

Each time you look at a photograph of the Universe, you aren't just seeing it as it was at a particular moment in time, but also in a particular wavelength (or set of wavelengths) of light! Different wavelengths can reveal different phenomena and components of the Universe, from dust and gas to starlight, plasma, black holes and beyond.

The view of the galactic center in four different wavelength bands. Atop, from the ATLASGAL survey at 870 microns; below that, from Spitzer in the mid-IR; below that, from ESO's VISTA in the near-IR, and at the bottom in visible light, where the dust obscures everything of interest.

Recently, the ATLASGAL collaboration, using the Atacama Pathfinder EXperiment (APEX) telescope, a 12-meter sub-millimetre dish atop a 5,100 meter Chilean Plateau, completed their map of the southern Milky Way. Spanning more than 400 square degrees, it is the most accurate map of our galaxy in this wavelength of all time, even defeating maps created in space.
