Upcoming Events

Finding Planet X and founding Space Australia 

Monday 5th April, 2021

6:30pm

Rami Mandow's career in science has been an incredible journey including founding Space Australia, drawing on the potential of Citizen Science and research into finding Planet X. He has recently been appointed as one of the Scientists in residence at Sydney Observatory. He is currently studying his Masters in Astrophysics through Swinburne Astronomy Online, in addition to being a student with Parkes Pulsar Timing Array project.

Astrobiology and Planetary exploration

Monday 3rd May 2021

6:30pm 

Dr Graziella Caprarelli is working on one of the most intriguing questions of our time - is their life on other planets? Dr Graziella will discuss her current research with the University of Queensland.

Total Lunar Eclipse

Tuesday 26th May 2021

Set-up From 5pm 

Our location is yet to be determined but this will be a fabulous evening using our telescopes, binoculars, naked eyes to view and take photographs of this year's total Lunar Eclipse. Will it be a blood moon?

Dark Side of the Universe

Monday 7th June 2021

6:30pm 

Professor Catherine Heymans will join us from the Royal Observatory Edinburgh, where she is Professor of Physics for Edinburgh University. 

Just over 95% of our Universe comes in the shrouded form of dark energy and matter that we can neither explain nor directly detect. Together, these two dark entities play out an epic cosmic battle with the gravity of dark matter slowly pulling structures in the Universe together, and dark energy fuelling the Universe’s accelerated expansion, making it ever harder for those structures to grow.

Catherine Heymans has used the world’s best telescopes to map out the invisible dark matter in our Universe and confront different theories on the dark Universe. She will explore this dark enigma and explain why she thinks in order to truly understand the dark Universe, we will need some new physics that will forever change our cosmic view.

Computing the Universe

Date TBC - this talk was rescheduled due to Covid-19 lockdown in WA.

Dr Paul Hancock will explain how radio telescopes collect information invisible to the human eye using techniques very different from optical astronomy. Optical telescopes can rely on physical lenses to collect and focus light and create images. Sadly there is no physical equivalent of a radio lens, and so the focusing and imaging of the radio light must be done virtually by a computer.

 

The new generation of radio telescopes are made with hundreds to hundreds of thousands of sensors, each collecting streams of radio waves. Modern radio telescopes thus require an enormous amount of computing resources just to make images. Radio astronomy is thus a very computational endeavour requiring a niche combination of astrophysics and computing skills to execute most projects.

 

This talk will cover some of the basic ideas of radio astronomy, discuss the current hot science topics, and show how Australian researchers are making the most of supercomputing facilities to support the Murchison Widefield Array (MWA) and Australian Square Kilometre Array Pathfinder (ASKAP) telescopes, as well as how this all feeds into the construction of the international Square Kilometre Array (SKA) telescope. The photograph By Natasha Hurley-Walker is of the MWA prototype.
