Professional astrophysicist and passionate science communicator. I investigate how galaxies form as well as studying the larger properties of the Universe, and try to explain it to as wide an audience as possible.
I was delighted when three RMIT students asked me to help explain the Aurora (the Northern / Southern lights) with them in this fantastic animation. There's something really engaging about this old school style that more recent digital graphics can miss. But decide for yourself..!
An amazing chance to open for Neil deGrasse Tyson in front of 5000 people, speaking about dark matter and generally hanging out with him backstage (and yes he's a top dude).
I made it to the panel of ABC's The Drum to chat about finding aliens with the amazing Breakthrough Listen project and the lead role Australia is playing in this endeavour.
Wednesday sees the 100th year anniversary since Einstein presented his “Field Equations of Gravity” to the Prussian Academy of Sciences which we know better today as General Relativity. This changed our understanding of the world, from Blackholes to the Big Bang and even GPS satnav. In honour of this momentous occasion I brought in a prop that really didn’t go very well...
I wrote an article for Cosmos Magazine explaining how NASA’s MAVEN spacecraft detected streams of Martian air blasted away by the Solar Wind. This tiny trickle (100g / s) was seen to increase 10-15x during even a moderate Solar Storm (or Coronal Mass Ejection). As the Sun was more active when younger these slow and fast processes of stripping air from Mars could explain how the red planet was transformed from a water rich world 4bn years go into the barren desert it is today.
A chat on the couch about how Mars was transformed from a world of oceans to the desert we know today (it was all the Sun’s fault!) I also spoke about a NASA archaeological dig into the centre of our galaxy looking for ancient stars and finished with the news that Google Lunar Xprize's private lunar space race is ON!
