The world's largest radio telescope array, the Atacama Large Millimeter/Submillimeter Wave Array (ALMA Observatory), located in Chile, celebrated its 10th anniversary on the 13th. The relevant officials emphasized the importance of international cooperation. The initial investment of ALMA Observatory exceeded 1.4 billion US dollars, which is the result of cooperation between 22 countries and regions including Europe, Japan, the United States, Chile, and others. It is located on the Chahnantor Plateau in the Andes Mountains of northern Chile, with an elevation of 5000 meters. Construction began in 2003 and was partially put into operation in 2011. It was officially completed and put into use in 2013. It has 66 huge high-precision antennas, and the collected data can be used to explore scientific issues such as the origin of the universe. The European Southern Observatory, the National Observatory of Japan, and the National Radio Observatory of the United States, which jointly operate the observatory, held a celebration on the 13th at the operational support base of ALMA Observatory at an altitude of 2900 meters, reviewing the contributions of observation and research over the past decade to scientific progress, and looking forward to the development of the next decade. ALMA Observatory Director Dougherty told Xinhua News Agency reporters that over the past decade of operation, The series of observations made by ALMA Observatory have made significant contributions to scientific development. For example, an important achievement was in 2014 when it captured a protoplanetary disk around a young star, providing clear images of planetary formation. Another well-known achievement is its participation in the Event Horizon Telescope organization in 2019, which collaborated to capture the first black hole photo obtained by humans. Dougherty stated that as astronomical projects become increasingly large and expensive, the important role of international cooperation becomes increasingly prominent. He welcomes the global scientific community to share high-quality data collected by the ALMA Observatory. It is understood that, The data generated by ALMA Observatory has supported the research of over 1400 researchers from dozens of countries and regions, and the results have been compiled into over 3000 papers. For the future vision, The ALMA Observatory stated that it will be committed to further improving operational efficiency, improving data transmission and upgrading data processing systems, generating more high-quality data, and better helping to explore the origin of the universe.
