In 2017 the Australian Astronomical Observatory joined the international Science Communication festival Pint of Science. The festival started in the UK and runs every May in over 150 cities across 12 different countries, including Australia. This year Pint of Science took place in 13 cities across Australia (including Sydney) over 15, 16 and 17 May 2017.
The Pint of Science festival aims to promote Science and Science Communication in a very relaxing atmosphere: in a pub with a drink. It brings scientists to a local pub to discuss their latest research and findings with the public.

The Australian Astronomical Observatory joined CSIRO, the ARC Centre of Excellence CAASTRO, and the Spanish Researchers in Australia-Pacific (SRAP) association as a sponsor of Sydney’s Pint of Science Festival in 2017. Our astronomer Ángel López-Sánchez (AAO/MQU) co-leaded the organization of the “Atoms to Galaxies” talks. These sessions included talks about Physics, Math, Chemistry and Astronomy and were hosted at Bar Cleveland, in Surry Hills.
Sydney’s “Atoms to Galaxies” program (which was the largest for Pint of Science Australia 2017) included talks about applied maths, search for exoplanets, explore quantum computing, play with the light, learn the origin of the chemical elements, map distant galaxies and challenge the laws of Physics.
The first night, “Elements in Space”, included talks by AAO astronomer and engineer Kyler Kuehn, who talked about astronomy neutrinos presenting the work he conducted in Antarctica for his PhD Thesis, and by AAO and Macquarie University astronomer Ángel López-Sánchez, who transported the audience to distant stars and galaxies to know when and how the atoms that compose our body were created.
In the third night, “Decodifying the Light of the Cosmos”, AAO astronomer an eResearch administrator Simon O’Toole described how we use the light collected by optical telescopes to search for planets around other stars, with the ultimate aim of finding an “Earth 2.0”.

Astronomers George Hobbs (CSIRO), Luke Barnes (University of Sydney) and Baerbel Koribalski (CSIRO), as well as physicists Dr. Sergio León-Saval (University of Sydney) and Prof. Jason Twamley (Macquarie University), and mathematician Emi Tanaka (University of Sydney) completed the “Atoms to Galaxies” program.

Besides organizing Sydney’s “Atoms to Galaxies” talks for Pint of Science Australia 2017, the Australian Astronomical Observatory was also present in the “Tech me out!” session Space Oddities on Wednesday 17th May. AAO’s optical engineer Rebecca Brown gave the talk “Capturing the Light of the Universe“, where she summarized the technologies used in optical telescopes, how they work and what we can learn, including example technologies developed at the AAO.
Addendum:
The details of the talks for the “Atoms to Galaxies” events in Pint of Science Sydney 2017 (info extracted from this AAO website) were:
Monday 15th May: Elements in Space
Tonight we will explore the conjunction between math, chemistry and astronomy. First Dr. Emi Tanaka (University of Sydney) will talk about how statistics feeds us, introducing the basic mathematical tools of statistics and their application in agriculture. Then Dr. Lamiae Azizi (University of Sydney) will be talking about how mathematical sciences coupled with computing have the potential to improve our lives. Finally, astrophysicist and science communicator Dr. Ángel López-Sánchez (Australian Astronomical Observatory / Macquarie University) will transport us to distant stars and galaxies to know when and how the atoms that compose our body were created.

Tuesday 16th May: Challenging the Laws of Physics
Tonight we will aim to change the Laws of Physics. Our first speaker, Prof. Jason Twamley (Macquarie University), will talk about quantum computing and why this research is so important. Then, astrophysicist Dr. George Hobbs (CSIRO) will explain what mysterious pulsars are and why their study is so important for physicists. After the break, cosmologist Dr. Luke Barnes (University of Sydney) will challenge our understanding of the physical constants to demonstrate that we live in a finely-tuned Universe.

Wednesday 17th May: Decodifying the Light of the Cosmos
Tonight we seek to get a better understanding of what the light can tell us about the Universe. Our first speaker, Dr. Sergio León-Saval (University of Sydney) will show us some of the photonic instruments that are now used in optical telescopes to direct the light of the stars from the optics to the detectors. In the second talk Dr. Simon O’Toole (Australian Astronomical Observatory) will describe how we use the light collected by optical telescopes to search for planets around other stars, with the ultimate aim of finding an “Earth 2.0”. Lastly, Dr. Baerbel Koribalski (CSIRO Astronomy and Space Science) will describe how radio-astronomers study the light of distant galaxies emitted in radio waves using facilities as the new “Australian SKA Pathfinder” (ASKAP) interferometer.
