The 76th Dutch Astronomers Conference (Nederlandse Astronomenconferentie, NAC) is organised by Leiden Observatory under the auspices of the Koninklijke Nederlandse Astronomenclub (KNA). This year’s NAC will take place on May 20,21,25,26 and 27, 14:30-17:00 each day. Mind the gap!


Like the 2020 edition – online, during the July 2020 Leiden EWASS Conference – also the 2021 Netherlands Astronomers Conference is going to be an online event. The RNAS/KNA board has chosen for a different set-up for this 76th NAC, however. The 2021 NAC will consist of five relatively short afternoon sessions, on May 20, 21, 25, 26 and 27, each from 2:30pm to 5pm. An assertive SOC designed a varied program, attractive for all of Dutch astronomers, including all RNAS/KNA members, with general review talks on exciting developments, with dedicated NOVA Network afternoons, featuring contributed talks by PhD students and others, and to conclude even with a prize ceremony – please read on!

The bad news is obviously that there will not be time for social interaction during breakfasts, lunches, dinners or at the bar. The good news is that registration is free-of-charge! The RNAS/KNA Board is grateful for the invaluable efforts of the Leiden LOC and the national SOC, and hopes that many RNAS/KNA members will register for this one-and-only NAC2021 (including the business meeting on day 5 …). We invite applications for contributed talks in the network sessions, with deadline April 30.

Invited talks will be given by Monika Moscibrodzka (RU Nijmegen), Tim Shimwell (ASTRON), Manuela Vecchi (Groningen), Silvia Toonen (UvA), Rony Keppens (Leuven) and Massimo Stiavelli (STScI).

Concluding the first afternoon session, on Thursday May 20, at 5pm, the NOVA Information Center will be offering a special webcast, dealing with JWST, hence a Webb-cast.


Participants can register their participation and submit their contribution over at the registration page. The abstract submission deadline was April 30. Abstract submission is now closed.
