Film Night - October: Light Pollution - The Disappearing Darkness
Monday 28 Oct, 2019 at 20:00Hrs
Venue: Stardome Observatory
Speaker/Host: Gavin Logan

This months film is a documentary entitled "Light Pollution - The Disappearing Darkness" which tells about how growing light pollution around the world is affecting astronomy and our views of the night sky. It also covers some of the solutions for this problem.



Introduction to Astronomy - Space Telescopes Part I - How they revolutionise astronomy!
Monday 04 Nov, 2019 at 20:00Hrs
Venue: Stardome Observatory
Speaker/Host: Chris Benton

Introduction to Astronomy - November

Come along and have fun learning about how space telescopes revolutionise astronomy!

This months discussion builds on our talk in October about large ground-based telescopes are ideally located in remote and elevated locations to minimise light pollution, atmospheric distortion and to get above most of the water vapour which absorbs infrared wavelengths.

Firstly, we will review the atmospheric absorption of most light wavelengths before introducing the astronomers ultimate solution. Space Telescopes Part I will introduce you to six famous space telescopes before focusing, no pun intended, on the Galex, Hubble andSpitzer Space Telescopes which view the universe in ultraviolet, visible and infrared wavelengths respectively.

From there, we will discuss how images from these telescopes are combined and colourised to give insight into astronomical processes and provide the pretty pictures we see on the internet.A case study of these techniques used on the Matariki open star cluster is included, followed by how the field of astrometry also uses space satellites.

Space Telescopes Part II in November, after recapping the main points from Part I,  will focus on the Fermi Gamma-Ray Telescope,Chandra X-Ray Observatory and James Webb Space Telescope followed by a discussion of the Cosmic Microwave Background satellites.

Both parts stand on their own,but we encourage you to come along and enjoy both.

Burbidge Dinner 2019
Friday 22 Nov, 2019 at 18:30Hrs
Venue: Ellerslie Events Center
Speaker/Host: Professor Joss Bland-Hawthorn

After Dinner Lecture:

"The Galactic Centre - a Window into the Future"

Professor Joss Bland-Hawthorn, (Director, Sydney Institute of Astronomy, University of Sydney)

The centre of our Galaxy harbours a massive black hole Sgr A* that is likely to be the oldest component of the Galaxy
along with the invisible dark matter around it. How this amazing object came into existence and evolved over 13 billion
years is intimately linked to the nature of the first stars, the chemical elements today and the evolution of dark matter
 and gas. Sgr A* is one of the fastest developing fields in astrophysics where discoveries are made every year.
For example, the most energetic particles ever detected by IceCube in Antarctica, and by telescopes in Namibia
and Argentina, are thought to have been created at the Galactic Centre. Our x-ray and infrared satellites pick up flaring
activity near the black hole each day. The speaker discovered that Sgr A* triggered a huge explosion about 2 million
years ago, when cave people walked the Earth; this was recently confirmed by NASA’s Fermi gamma-ray satellite.
The new ESO Gravity instrument tracks the motion of the closest stars to Sgr A* and detects movement every single
day! One star even reaches 32,000 km/s at closest approach, 12% of the speed of light. Other stars have escaped the
Sgr A* region being ejected at speeds of 2000 km/s into the Galaxy. So what does the future hold and what can we
learn from these remarkable observations? We will explore these topics and some crazy ideas.
Joss Hawthorn is one of Australias leading astronomers with the rare distinction of having made important contributions to both astrophysics and technology. He was born in Kent, educated at an Oxford boarding school before going to university in Birmingham (BSc) and Sussex (PhD). In the period 1985-1993, Joss was an astrophysicist at the Institute for Astronomy in Hawaii and a professor of physics at Rice University Texas. In 1993, he moved to the Anglo-Australian Observatory, Sydney, eventually to become Head of the research and development team.


Today, he is the Laureate Fellow Professor of The University of Sydney’s School of Physics, and Director of the Sydney Institute for Astronomy, co-Director of the Institute of Photonics and Optical Science, and Principal Investigator for the Sydney Astrophotonic Instrumentation Labs. He is a Fellow of the Australian Academy of Science and the Optical Society of America, serves on the prestigious Annual Reviews of Astronomy & Astrophysics Board, has published over 700 research papers in astronomy, physics, optics and photonics, and has been recognized with many international awards (see below), most recently the Miller Professorship to Berkeley (2018).


Joss’s team are building advanced machines, some funded by NASA, that are being installed on the world’s largest telescopes. In April 2017, one of his creations was launched on an Atlas-V rocket from Cape Canaveral on its way to the International Space Station, the first Australian university to do so. Joss lives in Mosman by Sydney harbour with his wife Susan and boys Christian and Luke. He is a jogger, a sculls rower at the North Shore Rowing Club and plays soccer for Mosman O35.

As well as our guest speaker there will be the prize giving for the New Zealand Astrophotography Competition including the Harry Williams Trophy for the supreme winner, and the Beaumont Writing Prize. A spectacular venue, great meal, cash bar and ample free parking

Film Night - November: Quantum Riddle - Quantum Entanglement
Monday 25 Nov, 2019 at 20:00Hrs
Venue: Stardome Observatory
Speaker/Host: Gavin Logan

This months film is a 2019 Documentary on Quantum Entanglement.
Einstein called it “spooky action at a distance,” but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that the phenomenon—two subatomic particles that mirror changes in each other instantaneously over any distance—is real. But a few doubts remain. This documentary follows a ground-breaking experiment in the Canary Islands to use quasars at opposite ends of the universe to once and for all settle remaining questions. 

This Film is 1 hour 10 minutes long and will be the only film shown at this Film Night.
