Astronomy on Tap London

Astronomy on Tap (AoT) offers a fun and relaxed environment for scientists, educators, writers and artists to share their work exploring the Universe with the general public in a bar

Originally started in New York City, AoT is not your typical science lecture. Each event usually features two or more accessible, engaging science presentations on topics ranging from planets around other stars to supermassive black holes to the beginning (and end) of the Universe. 

In 2020, Astronomy on Tap was brought to London by PhD students and Postdocs based at UCL. Due to the unfortunate timing coinciding with the Covid-19 outbreak, AoT London launched online following an innovative format, with its start on 8 April 2020. Our events featured short talks by researchers based in London, and were streamed on YouTube. Watch our past events here.


AoT London aims to bring together scientists and the people of London, making astronomy more fun and accessible regardless of age or background. As we plan for our formal launch in a bar near you when everything will be back to normal, we now seek active participation from both researchers and the public based in London and beyond. For the foreseeable future, all AoT London events will be live-streamed on YouTube. 

To keep up-to-date with events and announcements, be sure to follow our social media channels: Facebook, Twitter, and Instagram. On our social media we post exciting quizzes to entertain the public and the answers are then given during our live events. Don't miss out! For more information about the events and organisation, on how to get involved with AoT or to sign up to give a talk, please feel free to get in touch with us at astronomyontaplondon@gmail.com.

Our next live event will be on Wednesday, 23 June at 7pm BST, when Alejandra Jiménez Rosales (Radboud University) will talk about "The polarised image of the supermassive black hole in M87". The Event Horizon Telescope Collaboration recently updated the famous black hole image from 2019, in which a new fascinating pattern on top of the ring shows the polarisation of light. Join us to discover what polarisation is, dive into the physical effects that go into our simulations and learn more about what polarisation can tell us about the black hole and its environment! Tune in to our YouTube live event here to find out!
