About the talk

Take a trip back in time, into our Galaxy's wild and dangerous past, with Professor Joss Bland-Hawthorn.

A dormant volcano a supermassive black hole lies at the heart of our Galaxy. Four million times the mass of our Sun, it has probably been growing for 13 billion years.

Until recently, we thought our Galaxy's black hole had been quiet for a very long time. But exciting new evidence suggests that the centre of our Galaxy was erupting just two million years ago, when early hominids walked the Earth.

The echo of this amazing event can be seen today, imprinted in the night sky.


About the speaker

Professor Joss Bland-Hawthorn (Sydney Institute for Astronomy, University of Sydney) is an astrophysicist who has worked in the UK, the USA and Australia. He specialises in research on galaxies.

With Professor Ken Freeman from The Australian National University (ANU), he developed the field of "Galactic archeology" the process of uncovering the details of the history of our Milky Way Galaxy.

Professor Bland-Hawthorn is also an expert on developing instrumentation for astronomy, and is helping to pioneer the new field of astrophotonics: using photonic devices in astronomy.


The Allison-Levick Memorial Talk

The Allison-Levick Memorial Lecture is funded by a bequest from Mr Jack Allison-Levick, a Melbourne psychiatrist with a life-long interest in astronomy. Mr Allison-Levick had seen photographs taken with the AAO's telescopes by astrophotographer David Malin, and was moved to leave money in his will for talks that would enhance the public understanding of astronomy and further the reputation of the Observatory.
