The European Week of Astronomy and Space Science (EWASS, formerly JENAM) is the annual meeting of the European Astronomical Society (EAS). With more than 25 years of tradition, it has imposed itself as the largest conference for European astronomy. In addition to plenary sessions and the award of prestigious prizes, the conference hosts many symposia held in parallel, as well as special sessions and meetings.

The EAS together with one of its affiliated societies, organises the annual EWASS conference to enhance its links with national communities, to broaden connections between individual members and to promote European networks.

EWASS 2018 is to be held for the first time in Liverpool, United Kingdom from 3 to 6 April 2018. This unusual period in the week just after Easter was chosen to avoid a date conflict with IAU 2018 to be held in Vienna in August. It will be held jointly with the National Astronomy Meeting (NAM) of the Royal Astronomical Society. The Astrophysics Research Institute of Liverpool John Moores University is responsible for both the local and scientific organising committees of the conference. The conference is expected to welcome more than 1000 astrophysicists from all over Europe and even beyond.

Ethics and Anti-harassment statement

The EAS considers its annual EWASS meetings to be a privileged occasion for free and frank interchange of scientific ideas, as well as for the nurturing and creation of professional and social contacts. Any abuse of power or inappropriate behaviour has no place at the EWASS.

On 23 January 2018, EAS Council has adopted the EAS Ethics Statement and Guidelines for Good Practice. These will apply during EWASS and all participants are urged to read the document and follow its recommendations.

The RAS kindly requests that all of its meeting attendees, including those at EWASS 2018, adhere to the Code of Conduct for RAS meetings.
