I got a little carried away with the ridiculous scale of the latest explosion in space, outshine the entire Milky Way twenty times over. We have no idea how to produce this level of explosion. Then there was brief chat about SpaceX and its unfortunate crash on a sea barge then a final rant about the wonders of Pluto!

The Project invited me on the show to chat about an astounding discovery... A new tiny faint point of light appeared in the sky, 10000 times faint than could be seen by the naked eye, but when we realised it was 3.8 BILLION lightyears away it was clear that it must be astoundingly bright to even reach this faint level. This was the brightest supernovae ever recorded - ASAS-SN-15lh

One of my great passions in life is reading, and I jumped at the chance to wax lyrical about my top books I’d read this past year on Radio National. Sarah Dingle was a champ, allowing me to get a bit carried away with some of the themes of the books...

2016 is shaping up to be an incredible year for space exploration with ESA’s ExoMars spacecraft heading to Mars, NASA’s Juno mission reaching Jupiter on 4th July and an entirely new type of telescope called LIGO looking out into the universe for Einstein’s final prediction Gravitational Waves..!

After an outstanding year of science and space events I grabbled with the thorny issue of summarising my highlights to a top 10 for theconversation (I could have easily listed another ten!) Unsurprisingly the main story of the year was Pluto.

I chatted to Scott and Kumi about the upcoming Geminids meteor shower, why it’s so good this year as well as where and when would be best to watch. If you want more details I wrote about this online with approximate times for Australia.

DRAGONS is out! Our first six collaboration papers are on the arXiv and submitted to the journals. Can’t describe what a relief this is for myself and the team..! Led by U.Melb’s Professor Stuart Wyithe it's been a few hard years of science, simulating the first galaxies after the Big Bang and trying to figure out what these look like from telescopes on Earth, 13 billion years later (and 40 billion light years distant) but finally the results are in and they’re amazing.

My thoughts on the newly announced Innovation Statement from new PM Turnbull’s government. There’s a lot to like in this package of over 20 policies/initiatives and I wrote a piece for ABC The Drum focussing on those that will impact research most directly.

It was a busy day preparing for the Government’s new innovation policy, I chatted about what I hope to see and also what I thought would happen. Then I was able to sneak in some tips on viewing the Geminids meteor shower next week as well as some astonishing new images from the recent New Horizons flyby of Pluto.

Deeply honoured to be featured alongside everyday Australian legends as Commbank’s Australian of the Day campaign. Fun chatting to them about my work on Dark Matter as well as helping inspire and educate Australians about the awesomeness of science.

I had a horribly awkward fanboy moment when I got to meet the legend himself Buzz Aldrin! There are few people in this world I consider a living legend but Buzz is one, so getting to shake his hand and then hear about his experiences on the Moon and his hoped for plans about getting to Mars was incredible.

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!

I explained to Channel 10 that NASA’s MAVEN spacecraft has seen the solar wind from the Sun strip Mars of 100g of atmosphere a second (that’s a quarter pounder burger of air). During solar storms this can increase 10x-15x as much meaning that the younger and more active Sun was easily capable of stripping Mars of it’s atmosphere. This turned Mars from a world of oceans 4bn years ago into the desolate desert it is today. It also highlights the importance of our magnetic field on Earth which protects us from a similar fate!

I spoke to Sunrise on 7 about the asteroid TB145 akak “Spooky” or the “Great Pumpkin”. An asteroid flying by Oct 31st 17.05 UTC (Halloween!) which is 4am Nov 1st for Melbourne. Awesomely it looks like a skull. It will pass by over a third further out than the Moon, although a close shave by astronomy standards there's seriously no threat AT ALL so don't panic, just enjoy the show.

I’m CI of the dark matter detector SABRE at the Stawell Underground Physics Laboratory and can proudly announce that we've been funded by the ARC! Australia will now join an international search for the nature of dark matter as the first site in the Southern Hemisphere.

A spooky interview as an object (fittingly a 'dead' comet) will flyby Earth on Halloween just further than the Moon's is from us. I spoke about the furthest galaxies from us that Hubble has found (using a high-tech martini glass) and a dead star that is tearing apart the planets in its solar system that will likely happen to use in five billion years time.

One of the best science lectures I've ever seen was at Monash University by Caltech's legend GR expert Prof Kip Thorne giving the Einstein Centenary lecture to celebrate a century since General Relativity was released to the world. Fittingly, he used the examples of Interstellar's Black Holes, time dilation and 5-dimensional (bulk) beings to make the topic all the more accessible to the (sold out) auditorium.

My thoughts on a mysterious star that has its light blocked as something huge passes between us and this star. It could be a swarm of comets blocking the light as a nearby star flew by and disrupted comets in the Oort Cloud and sent them spiralling inwards. Another option is that it could be a Dyson Sphere, essentially the natural extension of solar panels in space that surround the star and block its light.
