IAU XXX General Assembly Draws to a Close

The XXX General Assembly of the International Astronomical Union (IAU) ends today in Vienna, Austria. One of the largest astronomy meetings ever held, it has seen a huge assortment of frontline astronomy topics presented, with six symposia, 22 multi-session focus meetings, nine IAU Division meetings and dozens of IAU Commission meetings.

The IAU XXX General Assembly in Vienna, Austria, ends today, Friday, 31 August 2018, after two busy weeks packed with symposia, meetings and events. The General Assembly was an enormous success, with more than 3000 attendees from 89 countries across the world, including almost 100 members of the press. These numbers made it one of the largest IAU General Assemblies ever organised. The participants enjoyed a vast collection of scientific presentations in six symposia and 22 focus meetings on research, development, advancement and collaboration within astronomy. The programme also included music performances to entertain the many visitors.

On the occasion of the 2018 General Assembly, 10 new National Members joined the IAU: Algeria, Cyprus, Ghana, Jordan, Madagascar, Morocco, Mozambique, Slovenia, Syria and the United Arab Emirates. This brings the total IAU membership to 83 countries (National Members). At the Closing Ceremony, the General Assembly also approved 1248 new IAU members, bringing the total to over 13 500 members. Some of the new members have been accepted into two newly established categories: junior members and honorary members.

Of the Individual and Junior Members who joined the IAU on the occasion of this year’s General Assembly, 30% were female, which is a significant improvement on the previous gender balance in the Union — just 18% female Members.

Five new Resolutions were presented and voted on at the General Assembly:

  1. Resolution A1: the 10-year IAU Strategic Plan for the years 2020–2030.
  2. Resolution B1: the Geocentric and International Terrestrial Reference Systems and Frames.
  3. Resolution B2: the Third Realisation of the International Celestial Reference Frame.
  4. Resolution B3: the preservation, digitisation and scientific exploration of historical astronomical data.
  5. Resolution B4: the renaming of the Hubble law.

All five Resolutions were accepted by the General Assembly, although Resolution B4 — the proposition to rename the Hubble Law as the Hubble-Lemaître law — will, in addition, be voted on electronically by all IAU members in the fourth quarter of 2018, in order to ensure wider participation in the decision. Prior to the General Assembly, Resolution B4 was also submitted to a period of extensive consultation with the community.

At the Closing Ceremony, it was also announced that the XXXII IAU General Assembly in 2024 will be held in Cape Town, South Africa. This will be the first time an IAU General Assembly will be held in Africa.

One of the highlights of the General Assembly included the launch of the IAU100 project, the IAU100 exhibition, which presented highlights in the development of astronomy and space research since the foundation of the IAU. There were also celebrations such as the first decade of Austrian participation in ESO, as well as 50 years of the Astronomy & Astrophysics journal. Awards and certificates were presented to the IAU PhD Prize winners, as well as to other distinguished Union members including Carolina Ödman for her pioneering work in astronomy outreach, development and education.

The 2018 General Assembly also featured the launch of Inspiring Stars, a travelling international exhibition that allows audiences to experience astronomy as a universal science that celebrates, encourages, reinforces and addresses diversity and inclusion in both education and teaching, as well as at a professional level.

The highly successful Young Astronomer and Women in Astronomy events included social lunches and a series of talks, the latter of which included discussions of gender statistics, gender equality issues, and gender-related initiatives from around the world.

The four IAU Officers for the next triennium are:

  1. President: Ewine F. van Dishoeck
  2. General Secretary: Maria Teresa V.T. Lago
  3. President-elect: Debra M. Elmegreen
  4. Assistant General Secretary: Ian Robson

In his parting words, the outgoing General Secretary Piero Benvenuti said: “This has arguably been the most inclusive IAU General Assembly in history. In the halls of the Austria Center Vienna there were scores of children in and around the daycare centre, many visually impaired, people hard of hearing, and, in general, people from more countries and cultures than ever before. This makes me very happy and a little bit proud.

During the General Assembly, many public outreach events took place in Vienna, reaching more than 2000 students and laypeople. This included 10 stargazing parties, teacher training sessions, and school visits to the exhibition hall, as well as talks and exhibitions on topics such as light pollution, and also science and art.
