About NAOJ Chile

The Atacama Large Millimeter/submillimeter Array (ALMA) is a giant radio telescope which was constructed in Chile in cooperation with the Republic of Chile, through global partnership of East Asia (including Japan), North America, and the member states of the European Organisation for Astronomical Research in the Southern Hemisphere (ESO). ALMA is an array of 66 antennas (composed of 12-m and 7-m antennas in diameter) designed to observe astronomical objects at millimeter/submillimeter wavelength, which is at the shortest wavelength range in the radio wave spectrum. The NAOJ Chile was established in April 2012 with the mission to complete the construction of ALMA and support its science operations so that ALMA continuously produces significant scientific results. In January 2019, the NAOJ Chile spun off the NAOJ ALMA Project; the new NAOJ Chile is focused on the mission to manage and oversee the NAOJ researchers working for the Joint ALMA Observatory (JAO) and to facilitate the on-site operations of ALMA in Chile.
