Today’s feature interview is with planet hunter Dr Belinda Nicholson, Postdoctoral Research Assistant at the University of Oxford, Department of Physics. Belinda’s current research involves exoplanet hunting using exotic telescope data. Previously she has investigated the behaviour of ‘teenage’ stars, and her work has taken her all over Australia and the world, from presenting her work at conferences in Europe and the United States, to collecting data on mountains in New South Wales and South America. Right now, she’s in Oxford / London. In the sky for observers and astrophotographers: Our regular feature ‘What’s Up Doc’ is with Dr Ian ‘Astroblog’ Musgrave. He previews the excellent observing opportunities over the next two weeks, and he gives us a good look at fernickety Betelgeuse. In the News: 1. More light polluting satellite constellations 2.

Over the holiday season we are taking a break, and we are producing a couple of ‘Holiday Specials’ where we reprise some episodes as ‘double headers’ where we provide 2 feature interviews from our 2019 playlist. We have stripped out Dr Ian Musgrave’s ‘What’s Up’ segment and my ‘In the News’ segment, giving you two uninterrupted interviews. In this reprised episode we have interviews with Dr Ashley Ruiter – Supernova scientist and Steve Olney – Amateur Radio Astronomer. Dr Ashley Ruiter is ARC Future Fellow and senior lecturer in the School of Science at UNSW Canberra, Australia. She specializes in Type Ia supernovae. Steve Olney has established the Hawkesbury Radio Astronomy Observatory in his backyard. Steve has constructed a Yagi antenna array, coupled it with a receiver and observed the Vela pulsar glitching, 900 LY away.

Our feature interview today is with Dr Geraint Lewis who a Professor of Astrophysics at the University of Sydney, whose research includes cosmology and galactic archaeology. and today he is going to help us look at the existential question “Are We Alone” . Also I’ll remind listeners that this is our last episode for 2019 before we take our holiday break, but we’ll be back in early February 2020, and if you are not already, there is another great Astronomy podcast you should listen to and that is The Skyentists with our friends Dr Ángel López-Sánchez, a Spanish-Australian astrophysicist working at the Australian Astronomical Optics (AAO) and in the Department of Physics and Astronomy of the Macquarie University in Sydney and the wonderful indigenous astrophysicist Kirsten Banks, who has just completed her Honours year and embarking on her PhD.
