Melbhenge on Thursday AND Friday evening

Alan Duffy

We have two chances this year - on both Thursday and Friday evening the Sun sets perfectly for MelbHenge which is lucky as it’s otherwise going to be a tougher time due to poor weather for the ever-growing grassroots effort to map out the best place to view it. Remember this phenomenon of a setting Sun framed by a mile long canyon of Melbourne's skyscrapers is both awesome but also dependent on favourable weather, but you only need a brief gap in the clouds to when the Sun is so low on the horizon, so head out from 8.15pm onwards and cross your fingers.

Last year most sat on Treasury steps, looking directly at the Sun unfortunately (please please don’t do that!) but for those who enjoy the photo from their phones please share it online with your location and hashtag so Swinburne University of Technology can map out the best viewing points and let’s get this as big as Manhattenhenge!

Stargazing Live: Back to Earth

Alan Duffy

Awesome. In the truest sense of the word. How else to describe Stargazing Live? A national science extravaganza that involved the great on screen scientists of our age (Prof Brian Cox, Prof Chris Lintott, A/Prof Lisa Harvey-Smith) explaining the latest science from the gorgeous Siding Spring Observatory. I was a permanent panel member trying to answer the public's questions on the Back to Earth show that followed Stargazing each night. The public were asked to help us find alien worlds using Exoplanet Explorer, by the of the three nights Brian was able to announce a world with four super-Earths all closer in than Mercury... Insane. I still can't understand how it formed. Truly one of the most incredible experiences I've ever been part of, thanks Stargazing!

Feeding black holes - ABC Breakfast News TV

Alan Duffy

An amazing discovery by the ALMA telescope of giant clouds of cold gas falling towards a supermassive black hole, seen as shadows against the bright glow from this feeding black hole. In addition I discussed the worsening global light pollution phenomenon and a surprise chain galaxy found by citizen scientists from Russia using the Australian Radio Galaxy Zoo!
