The Milky Way is the galaxy that contains our Solar System. Name “milky” word is derived from its appearance as a dim glowing band arching across the night sky whose individual stars cannot be distinguished by the naked eye. A new map of the Milky Way has been released, giving astronomers a detailed look at the cold, dense gas floating throughout our galaxy from which stars are born. The APEX telescope in Chile recently completed a map called ATLASGAL (The APEX Telescope Large Area Survey of the Galaxy) by using previously collected information from the Southern Hemisphere of the Galactic Plane, where a majority of the Milky Way’s mass bask.
This APEX Radio 40 Foot Telescope placed about 16,700 feet above sea level on the Chajnantor Plateau in Chile’s Atacama area, which helps astronomers to study the “Cold Universe” Dust and gas with temperatures near absolute zero.
