“Scientists, or at least their wild-haired fictional counterparts, promised us time travel and still have not delivered. Forget walking with dinosaurs or killing baby Hitler; I’d be happy just to warn my month-ago self not to make all the mistakes he’s about to. It’d also be nice to zoom past the next few months (year? years??) to the nationwide orgy of the post-virus era. Of course, none of these things are possible, because time travel doesn’t exist. But could it? That is the subject of this week’s Giz Asks, for which we reached out to a number of physicists…”
In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers at the Max Planck Institute for Extraterrestrial Physics have identified a previously unknown supernova remnant, dubbed "Hoinga." The finding was confirmed in archival radio data and marks the first discovery of a joint Australian-eROSITA partnership established to explore our Galaxy using multiple wavelengths, from low-frequency radio waves to energetic X-rays…
“Radio images of the sky have revealed hundreds of “baby” and supermassive black holes in distant galaxies, with the galaxies’ light bouncing around in unexpected ways…”
I worked with amazing poet Rosie Sitorus and she crafted a wonderful piece on how Australian Indigenous and modern astronomical views of the sky exist in beautiful tension and synergy. Click through to hear her fantastic reading.
Meet Dr Natasha Hurley-Walker! Natasha is a radio astronomer at the International Centre for Radio Astronomy Research, and helped to commission the low-frequency SKA precursor radio telescope, the Murchison Widefield Array (MWA), located in outback Western Australia…
“What's that large, faint ring in the middle of the image above? It's the remnants of a supernova explosion that took place less than 9,000 years ago, and would have been visible to Indigenous people across Australia at the time…
“On a clear night, the Milky Way dominates the sky above the Australian outback, arching overhead in a way never seen from the Northern Hemisphere. As wondrous as this looks, our eyes see only a tiny part of the spectrum of light emitted from the galactic plane, so astronomers have pieced together an image of how the same region would look if our eyes could see at the frequencies of FM radio, and it's spectacular…”
“The Federal Government's Australian Research Council (ARC) has recently announced the recipients of its Future Fellowship program, with four Curtin researchers receiving grants for a combined total of over $3 million.
One such recipient is Curtin Institute of Radio Astronomy researcher Dr Natasha Hurley-Walker, who joins RTRFM to discuss her work and what she hopes to achieve with the grant…”
“We humans are an energy hungry lot - and we get hungrier with each passing year. But what happens when we've chewed up all the energy options on Earth?
Astrophysicist Natasha Hurley-Walker has just the thing…”
“My husband and I lived four joyful car-free years in Perth, getting around by bicycle. On weekends we’d swap our city bikes for a beautiful custom tandem.
Then came the kids…”
“Over the course of human existence, we’ve made up all kinds of stories about what we didn’t understand - like werewolves howling under the moonlight, and the Earth being as flat as a crepe. We live and learn, and fortunately, we share our insight with others. Dr. Natasha Hurley-Walker is an award-winning astronomer that does just that…”
“With our world undergoing huge changes due to humankind's insatiable demand for resources, radio astronomer Dr Natasha Hurley-Walker will be at several events, including at SciTech, discussing topics such as looking for life on other planets….”
“Ever wanted to meet your historical heroes or explore the inventions of the future? We look at what science tells us about the possibility of travelling in time…” I’m interviewed on the BBC’s The Inquiry about all things space-time.
“Despite its reputation as a male-dominated field, STEM — science, technology, engineering, and mathematics — is filled with inspirational women who are putting in the work to change the world as we speak. Some of them are starting young, others are breaking boundaries further through their careers, but all of them are making new discoveries and chasing the future…”
“CURTIN University astronomy researcher Natasha Hurley-Walker is on a mission to smash stereotypes in 2019…”
“Balancing a scientific career with having a family isn’t easy. For early and mid-career women, just when they need…”
“Talk to radio astronomer Dr Natasha Hurley-Walker and you’ll never look at the night sky in the same way again…”
I appear on the world’s longest-running TV show, the BBC’s “Sky at Night”, exploring GLEAM with Prof. Chris Lintott.
“Local Astrophysicist Dr Natasha Hurley-Walker is giving us the opportunity to see the night sky in technicolor by creating a detailed map of the sky. She went around setting up low frequency radio telescopes around the Shire of Murchison, which ended up taking about 10,000 pictures of the sky…”
“Today in our feature interview we hear about some of her amazing research projects, including her all-sky survey of 300,000 galaxies…”
