This annual Astronomical Data Analysis Software and Systems (ADASS) conference, held in a different location each year, is a forum for astronomers, computer scientists, software engineers, faculty members and students working in areas related to algorithms, software and systems for the acquisition, reduction, analysis, and dissemination of astronomical data.

What Is ADASS?

The ADASS XXVII program will include invited talks, contributed papers, display sessions, tutorials, computer demonstrations, and special interest (“Birds of a Feather” or BoF) meetings.

What to expect?

An important element of the program is to foster communication between developers and users with a range of expertise in the production and use of software and systems.

Where is it?

The 27th edition of ADASS will take place in Santiago de Chile, in October 2017. For the first time, this long running conference will be hosted in Latin America.


In Chile, the sky isn't the limit!

Experience a journey to the stars in Chile! Observe constellations, planets, shooting stars and all manner of celestial bodies in the spectacular Chilean skies – the clearest in the entire southern hemisphere.

Chile enjoys more than 300 clear days per year and with little or no light pollution in the north, conditions are ideal for stargazing under open skies. For a truly close encounter with the planets, visit one of the many astronomical observatories open to visitors.

In La Serena, Elqui Valley, San Pedro de Atacama, Antofagasta and Iquique you’ll find agencies which can arrange transport and accommodation and provide observation equipment for travelers.

Don’t miss the chance to visit some of the world’s leading scientific observatories. At sites like ALMA, Tololo and Paranal, you can witness the state-of-the-art technology used to investigate the universe.

Santiago de Chile, 27-29 October 2017 

The vision of the Virtual Observatory (VO) is to allow astronomical datasets and other resources to interoperate seamlessly. The VO resources are provided by different organisations spread all over the world, but they feel as if they are inside the user’s computer.

The International Virtual Observatory Alliance (IVOA) is an organisation that debates and agrees the technical standards that are needed to make the VO possible. It also acts as a focus for the VO vision, a framework for discussing and sharing VO ideas and technology, and a body for promoting and publicising the VO.

The IVOA Interoperability Workshops provide a semi-annual venue for discussion and development of Virtual Observatory standards and VO-based applications, and are open to those with an interest in utilizing the VO infrastructure and tools in support of observatory operations and/or astronomical research.

This meeting is hosted by the Chilean Virtual Observatory (ChiVO), and is supported by the Technical University Federico Santa María (UTFSM). The workshop will be held at the Sheraton Conference Centre in Santiago de Chile, Chile, the same venue as ADASS XXVII, during the three following days.
