The first ever contest allowing members of the public to name ExoWorlds begins its first round today, offering the registered clubs and non-profit organisations the chance to nominate their favourite systems to take through to the next rounds.
As previously announced, the IAU is organising a worldwide contest to give popular names to selected exoplanets along with their host stars, among a list of hundreds of well-characterized exoplanets it has offered for public naming. Today the IAU officially opens this NameExoWorlds contest. The first round of the competition allows all registered clubs and non-profit organisations to nominate up to 20 ExoWorlds (exoplanetary systems and their host stars) to be made available for the next stage of the contest, where names can be proposed for the most popular ExoWorlds.
Although people have been naming celestial objects for millennia, the IAU was delegated the task of assigning scientifically recognised names to newly discovered celestial bodies by its member countries. The NameExoWorlds contest is the first opportunity that the public will have to name not only exoplanets, but also, for the first time in centuries, to give popular names to stars — those that have known exoplanets in orbit around them.
To participate in the contest, clubs and non-profit organisations must first register with the IAU Directory of World Astronomy. The deadline for which has been extended to 23:59 UTC on 15 May 2015.
The deadline for the first stage of the contest itself is at 23:59 UTC 15 February 2015, when nominations for 20 ExoWorlds to be named will close. In the next phase, once the most popular ExoWorlds have been identified, the stars and planets will be made available to all registered clubs and organisations to submit their desired names. Each club or organisation can then propose a name for one ExoWorld, with all submissions having to abide by the IAU Exoplanet Naming Conventions and be supported by a detailed argument for their choice. When this stage has concluded, the public worldwide will then be invited to vote on their favourite proposed names.
The final results are expected to be announced at a special public ceremony held during the IAU XXIX General Assembly in Honolulu, USA, 3–14 August 2015.
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.
