This is the heart of darkness.
The gravity of the blackhole is so great it casts a ‘shadow’ 2.5 times larger than itself (as defined by its event horizon) against the glowing material swirling into its maw.
That darkness is the size of the solar system but even so 6.5 billion Sun’s worth of mass crushes up pretty small when you’re a black hole.
Turn your smartphone into a cosmic ray hunter with the free CREDO app! Currently available on Android (any Apple developers out there get in contact) and already with 2.5 million detections the growing userbase is helping us search for the most extreme events in the Universe. Not that this helped me with Virginia on News Breakfast who asked me some seriously tough (but as usual, brilliant) questions on the health risks of Cosmic Rays.
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!
OK two times in one week being on one of the biggest shows in the nation talking science? Amazing.
This time tried to explain the importance of NASA outsourcing the Return to the Moon to commercial aerospace companies (especially startups). It’s an exciting development but needs careful watching.
An insane week of astronomy meant that I was able to explain the latest astrophysics discoveries to over a million viewers with The Project - but from the desk! This is a big deal, and my nerves knew it! The live studio audience really helps ramp up the energy too..!
To my amazement (and with gratitude to the judges!) I won the 2018 Celestino Promoting Understanding of Science at the Australian Museum’s national Eureka Awards. This is basically the highest honour scientists who communicate that science to the public and that it was decided by an illustrious judging panel who I look up too is an incredible feeling of support and acknowledgement.
It's nearly time for #NationalScienceWeek and we have updated the amazing (and free!) SciVR app to let you explore the universe in virtual reality on your smartphone! As before we are also giving you the chance to enter a ballot for free VR headsets that make the experience even better. Just head to www.scivr.com.au to register for that, download the app and book tickets for the live events (streaming online to over a dozen satellite events across Australia and the world!)
Melting icesheets of Antarctica Western Shelf are allowing that ancient continent to rebound at the fastest rate in the world (41mm a year!) as measured by GPS stations. It was explained by ESA's glorious GOCE satellite, published in Science, the reason why - the mantle under Antartica is less viscous (or squishier) than normal, which could be a good thing for our planet. I took it upon myself to explain why this makes a difference on ABC Breakfast News TV with a bowl of honey and peanut butter... Rather proud of this explanation.
I've kept the previous post up but sadly it's with regret that I have to pass on the message from Lateral Events that despite all our best efforts, What’s NEXT? has been cancelled in Sydney, Melbourne and Brisbane. All ticket buyers will be provide with a full refund within the next seven days (i.e. mid-August latest) by Ticketmaster or Ticketek. Sorry all.
I cannot believe I get to write this but Nobel Prize-winning and Interstellar science consultant Prof Kip Thorne is touring Australia and I AM ON STAGE WITH HIM! Prof Kip Thorne is quite literally one of the smartest humans in the world, co-sharing the Nobel-prize for finding gravitational waves.
Tickets are out NOW. Get them at the LateralEvents link and I'll see you soon Australia... but more importantly you'll see the future with Prof Kip Thorne. And that is an unforgettable experience.
Over half a century ago this nation became only the third in the world to build and launch a satellite from its own territory. Since that time aerospace ambitions in Australia have waxed and waned but with the announcement by the Turnbull Government of a National Space Agency, led by former CSIRO-head Dr Megan Clarke, it is clear that we are ready once again as a Nation to take our place in space.
The Victorian Minister for Industry and Employment Ben Carroll as well as Victoria's Lead Scientist Dr Amanda Caples believe that the natural home for this Agency is right here in Melbourne and were good enough to let me launch the bid alongside them, at Swinburne's Eric Ormond Baker Charitable Fund Remote Observing Facility in front of media from every TV, print and radio station. It was an unbelievable experience..!
The latest series of the ABC Radio National podcast #CosmicVertigo is out and we're taking things to the EXTREME. I have to say I have the most fun with Dr Amanda Bauer recording these, they're made for your listening pleasure so I hope you enjoy it as much as I do... subscribe where you get your podcasts. Rate and review etc.
However this time you can also ask us questions online or by email (especially if you record them!) and we'll feature the best (or at least the ones I can answer) on the show. Enjoy!
It's hard to put into words how significant Prof Stephen Hawking was for me on a personal level. His book "A Brief History of Time" was a defining moment as a young teenager to realise that you could have a career to explore the Universe; to spend a life studying the nature of expanding universes, blackholes and dark matter. More important than even his science he also showed the value of communicating that science.
His death hit me hard and it was a crazy day speaking on radio, TV and print to explain just why he was such an incredible and unique figure. I've shared a few of these TV interviews below. The first TV interview I ever gave was about him, and I was honoured that I could also speak at the end.
The Australian Space Agency review is to be released in a matter of days but do you know what it means for you, your children's future careers or even how much you already use space in your everyday life? Well with the team at The Royal Institution of Australia we put together a package answering all of these issues on Australia's Space Future. I'm really proud of the team's exhaustive efforts and also amazed by the careers of talented female scientists and engineers like Andrea Boyd, Flavia Nardini and Lisa Stojanovski who we were able to feature. In space our future really is unlimited.
It was truly a remarkable privilege to be one of the #CHOOSEMATHS Ambassadors and speak to 400 young girls about the value of maths in their careers. My thanks to AMSI for the opportunity as well as allowing me to hear the fantastic female ambassadors onstage - their stories and range of careers will inspire that audience to know a background in maths is a valuable (and valued!) one for any future job they may strive towards. Also my thanks to IMAX Melbourne for hosting us all, it was a fantastic place to enjoy the #CHOOSEMATHS ambassador's career videos - for more on why I think maths is key to all our futures (and in particular for women) head to the women in education special in The Australian #IWD2018
Incredibly excited to announce that Inspiring Australia has once again decided to support the Science in VR live experience with a National Science Week grant! We will give two live Virtual Reality (VR) talks using the SciVR app with bespoke Google cardboard VR headsets, as well as coordinated regional viewing parties, all with tailored educational material for the hidden universe! This year I will joined by my amazingly talented colleague Dr Rebecca Allen, can't wait to reveal more info soon on this! But you don't have to wait for the show to enjoy the app, just head to the Apple AppStore or Google Play and download SciVR for free, and can buy headsets from the Swinburne Bookshop for an even more immersive experience.
It's truly a remarkable thing to get to present your research to the Assistant Minister for Science, Jobs and Innovation Zed Seselja alongside fellow scientists in ecology, quantum computing and mining... this is what makes Science Meets Parliament such a unique experience and one I'm proud to have assisted as an executive of Science & Technology Australia.
One of the coolest parts of my job is that I can take film-crews around the world and showcase the incredible science and technology that is out there, but seeing the SpaceX Falcon 9 rocket launch at NASA's Kennedy Space Centre just tops everything. My huge thanks to ABC Catalyst for letting me reveal the change space race that means the return to the moon is a competition between startups not superpowers. This is a topic I raved about in the Sydney Morning Herald, and there was also a really nice review of the TV episode in The Australian. You can watch the episode online on ABC iView.
At the truly epic World Government Summit I was privileged to lead the discussion of Mars settlement by the best and brightest from the UAE Space Agency and make the broader case for space with an international panel. Apart from that I got to hear from Forest Whitaker, Neil DeGrasse Tyson and Michio Kaku all in one day..! The #worldgovsummit is truly an extraordinary meeting of the world’s best minds. Just as exciting will be to see the new businesses and activities that come from this meeting, I certainly aim to work more closely with an international range of impressive people, all with varied backgrounds I could never hope to have met at any other meeting. It was a genuine pleasure to meet and discuss space technologies with the extraordinary young engineers of the Mohammed bin Rashid Space Centre. I have to say the task facing the program director for Mars 2117, Saeed Al GerGawi, are humbling - but he and his team are more than up to the task if this gorgeous VR tour of their Mars City is anything to go by!
The grassroots effort to map out the best place to view MelbHenge as the Sun sets between a mile long corridor of Melbourne's skyscrapers continues to grow. This headline photo courtesy of LookAboutPhotography is just one incredible example of that.I'm always amazed at how many people get out and share their photos of this epic event... but we still don't know where best to view it! So we asked Melbournians to take a photo, share the location and use #MelbHenge so Swinburne University of Technology astronomers could update our map of the city to make this event bigger and better each year. Last time was featured on the BBC world news, let's see what we can do in the years ahead.
This is an incredible honour and something I'm delighted to finally announce but after a national application process I've been chosen as the new Lead Scientist of the Royal Institution of Australia, home of Australia's Science Channel.
Australia, and the world, faces significant challenges ahead but it will be more science and technology not less that will see us through. That’s why it’s so critical we continue to explain and share the latest breakthroughs by Australia’s researchers and inspire the next generation into STEM. At Australia’s Science Channel we can ensure the best and most inspiring science stories are fed directly into classrooms around the nation, and further shared around the world.
I hope I live up to the great legacy of the Royal Institution and am able to play a positive role in raising science's profile, and science literacy more generally, in Australia!
I loved making this short ABC ME series with the wonderfully talented and ever enthusiastic Grace Koh trying to explain the answers to questions that we all think of, while restricting ourselves to a green screen and about 3 minutes in total. You can watch all 5 episodes on iView or catch them as interstitials between your favourite shows on ABC ME. Also who doesn't love a big red button?!
Todd Sampson is insane. There. I said it. I understand physics, I trust 100% in the universality of the laws we explore in Life on the Line, but I certainly don't have 100% trust in the engineering. In episode 3 we discuss Friction by throwing Todd off a bungee jump without it being secured (simply interleaved pages of a phonebook). The principle of geometric amplification of the friction means that these phonebooks won't slip by. Everything else however could go wrong. In episode 4 we discuss Conversation of Energy by using a one tonne wrecking ball. This actually DOES go wrong. Yet still he risks his life. I love Todd's trust in my calculations, I just wish he wouldn't actually put his Life on the Line with them.
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!
I've been involved in some mammoth science communication events, and I firmly believe to ensure the role of STEM in our society we need these huge shows to make science cool again. I shared my thoughts on this and alarming decline in STEM enrolment rates on theconversation.
A stunningly beautiful project to explain the night sky to a younger audience on ABC ME by Camilla Hannan. If you don't feel captivated by the visuals, and awed by the wonderful dialogue (my bits aside) then you have no soul. Seriously though, have a watch on iView, I'm so proud to have been involved in this.
The new ABC Radio National science podcast hit the airwaves and I cannot be prouder of this show. Alongside my rantings is the insightful, measured yet ever enthusiastic explanations of my friend and co-star Dr Amanda Bauer. The entire series is run by the ABC's astoundingly talented producer Joel Werner. Subscribe and have a listen wherever you get your podcasts (iTunes).
The alignment of the setting Sun with Melbourne's Hoddle Grid only occurs twice a year, causing a beautiful sight of the Sun framed by a mile-long corridor of skyscrapers. The astronomy is easy, but where is the best location to view this? Which of the East-West streets (Collins, Bourke, Lonsdale or LaTrobe?) and what intersection as the trams and trees can get in the way... I asked the City of Melbourne to get out and snap photos and post online with their location using the hashag #Melbhenge to crowd-source the answer. Incredibly the request was shared on ABC Melbourne radio, The Age, Broadsheet and finally to a world-wide audience on the BBC. Amazing. Stay tuned for the best location for November 3rd's event as I go through all the incredible photos (like the image I've grabbed from Rachel Dexter on Collins St) from this event.
My regular column in theconversation (as well as appearance on ABC Breakfast News) explored a Thanksgiving meal that was out of this world, as well as the beginning of the end for the Cassini mission (but not without a spectacular final view) and a new fuel-less rocket that set the internet alight might be a misfire after all.
A new rocket that seemingly can create thrust without using fuel to push backwards has just been published. My thoughts in news.com.au were not entirely positive. Simply put this would break Newton's 3rd law, and also translation invariance (or the idea that the laws of physics don't change in one spot to another). If this rocket really doesn't need fuel to create thrust than that would be the end of physics as we know it. Instead my guess is that this is likely just thermal expansion as the microwaves (inside the EM drive) are turned on and heat it.
Amidst the exciting news of landing on comets and SpaceX plans to get to Mars, NASA released astounding findings that the smallest planet Mercury actually has tectonic activity just like Earth. Such a small world should be geologically dead and yet it has features that appear unweathered by bombardments from meteors meaning that they are no older than a few million years. It means Mercury joins Earth as the only rocky planet to have tectonic activity, and also means it may have Earthquakes (or should that be Mercury-quakes?)
I wrote about it in theconversation and chatted to ABC Breakfast News TV as well as ABC 702 radio.
