Experts from 33 countries will attend the global Astronomical Data Analysis Software & Systems (ADASS) conference, which brings together astronomy and computer science. Organized by the Atacama Large Millimeter/submillimeter Array (ALMA), the European Southern Observatory (ESO) and the Universidad Técnica Federico Santa María (UTFSM), from October 22 to 26 for the first time in Chile, ADASS will seek to develop astronomy and other industries, providing an opportunity to promote local talent to the rest of the world.

Chile is a privileged setting for astronomic observation and data collection, generating an enormous amount of public data. The ALMA observatory alone generates a terabyte of data per day; the LSST will reach 30 terabytes per night by 2022 and the SKA 360 terabytes per hour by 2030.

This evolution implies a never seen before data storage and analysis challenge, and Chile is in a position to lead this progress with the support of data, communication and technology platforms and expert human capital with the support of this potent cloud computing era. Herein lies the importance of Chile’s debut as Latin American headquarters for the International Astronomical Data Analysis Software & Systems-ADASS Conference, which after 27 years in practice, has chosen the country as its meeting location.

“A modern observatory today is a true data factory, and the creation of systems and infrastructure capable of storing this data and analyzing and sharing it will contribute to the democratization of access to current, critical and unique information, necessary for the hundreds of groups of researchers of the Universe around the world,” says Jorge Ibsen, Head of the ALMA Computing Department and Co-Chair of ADASS.

The Chilean Virtual Observatory (ChiVO) and The International Virtual Observatory Alliance (IVOA), have worked together for years to define standards for sharing data between observatories around the world and to create public access protocols. Mauricio Solar, Director of ChiVO and Co-Chair of the ADASS conference, assures that Chile can contribute to astronomy, not just through astronomers, but also through the development of applications in astroinformatics that, for example, can help find evidence of extraterrestrial life.

Astroinformatics combines advanced computing, statistics applied to mass complex data, and astronomy. Topics to be addressed at ADASS include: high-performance computing (HPC) for astronomical data, human-computer interaction and interfaces for large data collections, challenges in the operation of large-scale highly complex instrumentation, network infrastructure and data centers in the era of mass data transfer, machine learning applied to astronomical data, and software for the operation of Earth and space observatories, diversity and inclusion, and citizen education and science, among other subjects.

The ADASS Conference will bring together 350 experts from 33 countries at the Sheraton Hotel in Santiago, and will be followed by an Interoperability Meeting of the International Virtual Observatories Alliance (IVOA), organized by ChiVO, from October 27 to 29. More information at

The Atacama Large Millimeter/submillimeter Array (ALMA), an international astronomy facility, is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile. ALMA is funded in Europe by the European Organization for Astronomical Research in the Southern Hemisphere (ESO), in North America by the U.S. National Science Foundation (NSF) in cooperation with the National Research Council of Canada (NRC) and the National Science Council of Taiwan (NSC) and in East Asia by the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Academia Sinica (AS) in Taiwan.

ALMA construction and operations are led on behalf of Europe by ESO, on behalf of North America by the National Radio Astronomy Observatory (NRAO), which is managed by Associated Universities, Inc. (AUI) and on behalf of East Asia by the National Astronomical Observatory of Japan (NAOJ). The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA.
