Definitely knowing that there are aliens out there requires us to see their signals, either radio waves from TVs say or twinkling lasers from their interplanetary communications. We can even think bigger and look for Dyson Spheres glowing red hot.
Read MoreNASA launched a new spacecraft DSCOVR to monitor the Sun and warn us of impending, potentially highly damaging, solar outbursts known as Coronal Mass Ejections.
Read MoreThe Beagle 2 lander remains have been discovered on Mars. I remember this launch and potential landing well, the silence from the lander was crushing. If only Colin Pillinger had lived to see its successful landing.
Read MoreMy look at the awesome year that's coming ahead in space exploration for 2015. There's new things from Rosetta around Comet 67P, SpaceX landing a reusable rocket and solar storms
Read MoreMy round up of the year that was in space, from methane on Mars, landing on comets, hundreds of alien worlds and more. It was a massive year in space!
Read MoreNASA is getting back into the crewed spaceflight game and although I am huge fan of SpaceX and reckon it will be the default choice for Low Earth Orbit we still need the NASA genius to get us to Mars.
Read MoreA non-science chat on the couch debating issues around the world although I managed to sneak in a discussion on AI
Read MoreI got to tell a younger audience about the fantastically exciting landing of Philae on Comet 67P.
Read MoreThe first paper from the "DRAGONS" team led by Prof Stuart Wyithe, investigating how the First Galaxies formed. Using a series of hydrodynamical simulations series known as Smaug we show that the first billion years after the Big Bang is a very exciting time, with the entire universe lit by a hidden population of small galaxies that current telescopes have yet to see. Reference: Duffy, Wyithe, Mutch, Poole 2014 MNRAS 443, 3435D.
Read MoreThanks to powerful supercomputers we can know create virtuals universes that on galaxy scales are hard to tell from reality. These then act as numerical laboratories within which we can test out new laws of physics or dark matter to see what that universe would look like.
Read MoreAccompanying a large online article on news.com.au about searching for alien worlds I recorded this little chat
Read MoreThe two year anniversary of the Higgs Boson discovery meant I got to chat with AJ about what it meant and more importantly what the future holds!
Read MoreThe first of a regular space round up section.
Read MoreIn this paper, I analysed the ability of radio and optical (visible light) telescopes to probe the nature of Dark Energy. I showed that radio telescopes are rapidly improving in capability and although starting from a low base they will rival the best optical telescopes by the time of the Square Kilometre Array (SKA). One issue is that the SKA demands such a large supercomputer that Moore's law might not get us such a machine by the time SKA is built. Reference: Duffy 2014 Annalen der Physik 526, 283D for the Special Issue "The Accelerating Universe".
Read MoreA fun chat on the couch with Michael and Virginia discussing the upcoming solar eclipse and the safest ways to view it.
Read MoreA long (~1 hour!) chat about astronomy, the nature of the Universe, how we know what we know about dark matter and why I ended up the other side of the world from where I grew up creating baby universes inside a supercomputer.
Read MoreFun interview with the amazing team of Dr's on the Einstein a go go show, chatting about an ancient star recently discovered by an Australian telescope
Read MoreA fun interview about the recent discovery of the oldest star, and a plug for an upcoming Science of Doctor Who show I'm involved in... (Thanks Matt!)
Read MoreA wonderful article on indigenous astronomy, and my own small efforts try to both teach (and learn!) about this fascinating tradition as well as the science underpinning it during a visit to Karratha in the Pilbara region of WA.
Read MoreOn the morning that Rosetta woke up after ten long years travelling to meet the comet I was invited to the ABC studios to chat about why this was important and what we can learn about our own past.
