IAU XXIX General Assembly Draws to a Close

The XXIX General Assembly of the International Astronomical Union (IAU) ends today in Honolulu, Hawai’i, USA. 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, dozens of IAU Commission meetings, and the first-ever daily general poster sessions taking place over the course of two weeks.

The IAU XXIX General Assembly in Honolulu, Hawai'i, USA, ends today, Friday, 14 August 2015, after two busy weeks packed with symposia, meetings and events. The General Assembly was an enormous success, with more than 3000 attendees from 74 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.

One new country joined the organisation on this occasion: Colombia. The General Assembly also approved around 1200 new individual IAU members at its closing ceremony, bringing the total to almost 12 500 members.

Four resolutions were approved by vote at the General Assembly. These included the confirmation and extension of the IAU strategic plan for astronomy in the developing world and the protection of radio astronomy observations in the 76–81 GHz frequency band.

It was decided that the XXXI IAU General Assembly in 2021 will be held in Busan, the Republic of Korea.

The newly elected IAU officers are:

  • Silvia Torres-Peimbert, Mexico, President
  • Piero Benvenuti, Italy, General Secretary
  • Ewine van Dishoeck, the Netherlands, President-elect
  • Maria Teresa Lago, Portugal, General Secretary-elect

Seven press briefings took place on a wide range of topics, from the slow death of the Universe to the first science conducted using night-time photographs taken by astronauts aboard the International Space Station, and received worldwide media coverage (see iau1508iau1509, iau1510 and iau1511).

Agreements were signed for five new coordinating offices in Armenia, Colombia, Jordan, Nigeria and Portugal. This agreement seeks to realise the social benefits of astronomy as part of the IAU's decadal strategic plan.

During the assembly, the NameExoWorlds contest also opened its public vote to decide the names of 15 stars and 32 exoplanets.

Several public outreach events took place over the course of the General Assembly, including a stargazing party, school visits to the exhibition hall and astronomers visiting more than a dozen schools, reaching about 2000 students.

The IAU is the international astronomical organisation that brings together more than 10 000 professional astronomers from almost 100 countries. Its mission is to promote and safeguard the science of astronomy in all its aspects through international cooperation. The IAU also serves as the internationally recognised authority for assigning designations to celestial bodies and the surface features on them. Founded in 1919, the IAU is the world's largest professional body for astronomers.
