The 31st Annual Conference on Astronomical Data Analysis Software and Systems


The 31st annual conference on Astronomical Data Analysis Software and Systems (ADASS) will be held physically in Cape Town at The Westin Hotel and online, on 24-28 October 2021, and hosted by the Inter-university Institute for Data-Intensive Astronomy (IDIA), Centre for Radio Astronomy Techniques and Technologies (RATT), and the South African Radio Astronomy Observatory (SARAO). This annual 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.

The ADASS XXXI program will include invited talks, contributed papers, posters, tutorials, focus demos, and special interest (“Birds of a Feather” or BoF) meetings. These activities aim to stimulate further development of software and systems to meet the data science challenges of astronomy.

The key themes for the 31st annual ADASS conference are:

  • Solutions for workflow management and reproducibility;
  • Understanding and improving machine learning;
  • Modernising and maintaining telescopes;
  • Building accessible and friendly user interfaces;
  • FAIR standards for astronomical data;
  • Teaching resources for astroinformatics and virtual observatory;
  • Image processing for the public and scientists;
  • Big data: How to deal with the 5 Vs (volume, velocity, variety, veracity, value); and
  • Citizen science in astronomy.


  • Oral / BoF / focus demo submissions: 22 Aug (Deadline extended)
  • Financial aid application: 30 Aug
  • Early registration: 15 Sep
  • Registration: 1 Oct (in person), 15 Oct (virtual)
  • Poster submission: 1 Oct
  • Digital materials upload: 15 Oct
  • Payment deadline – Early Registration: 1 Oct
  • Payment deadline – Late Registration: 15 October

At this time, the Local Organizing Committee is working on hosting a hybrid meeting, with some in-person attendance and likely a large number of virtual attendees. Please note that if the COVID-19 situation changes, in-person attendance is no longer possible; the meeting will switch to an entirely virtual format.

In the meantime, here is the list of invited speakers for this year’s key themes.

  • Rachel Street (Solutions for workflow management and reproducibility)
  • Michelle Lochner (Understanding and improving machine learning)
  • Eric Murphy (Modernizing and maintaining telescopes)
  • Kumiko Usada-Sato (Building accessible and friendly user interfaces)
  • Simon O’Toole (FAIR standards for astronomical data)
  • Chenzhou Cui (Teaching resources for astroinformatics and virtual observatories)
  • Urvashi Rao (Image processing for the public and scientists)
  • Emily Lakdawalla (Image processing for the public and scientists)
  • Andy Connolly (Big data: How to deal with the 5 Vs (volume, velocity, variety, veracity and value)
  • Meg Schwamb (Citizen science in astronomy)

Further details regarding the format will follow in the coming months. Among many things, we will be looking at solutions to maximise attendance for a hybrid meeting. In addition, this format brings some new scheduling challenges given the various time zones of our international community.

The International Virtual Observatory Alliance (IVOA) meeting usually follows the ADASS meeting. However, this year, the IVOA is planning for an entirely virtual meeting. Please visit for details regarding that meeting.
