Today in PASA we published a new image of our Milky Way at low radio frequencies, in unprecedented colour and detail. Here's just a tiny piece of it -- the whole thing is ten times bigger! We're seeing high energy electrons whirl around cosmic magnetic fields from exploded stars, and more!

Congratulations @tamarastro.bsky.social on your election as a Fellow of the Australian Academy of Science @science.org.au ! #ShineDome25

At the #SKAO 2025 Science Meeting in Gorlitz, Germany. And I'm in the Gods! Enough astronomers to fill a theatre ✨

The US budget cuts to NASA and the NSF are horrifying. Anyone in the world can sign this petition to reverse them - consider adding your name? www.congressweb.com/PlanetarySoc...

Last night I found out that the NSF math postdoctoral fellowship I applied for is being deleted because it does not comply with Trump’s executive orders on DEI in the federal government. I’m going to answer some FAQs and share some thoughts about this ordeal in this thread 1/n

Perth folks, I will be chatting with Rachel Rayner, Science Explainer, at the FRINGE Festival! This is a huge first for me -- next year, maybe I can do the same while fire juggling?! In all seriousness come and support me and other scientists :D Tickets here: fringeworld.com.au/whats_on/aus...

Not my usual research topic, but a bit of fun for a local SFF convention :) I analysed the astrophysics of the Legend of Zelda games -- using the same techniques real astronomers use! Good fun, educational, and the audience loved it!

Fabulous to see this new long-period radio transient published! The longest period yet -- and it has interpulses, strongly implying a 'lighthouse' of radio waves passing over our line-of-sight.

Beautiful writing from the wonderful @aussiastronomer.bsky.social. Sort of about our Stargazing Live exoplanet hunt, but also not.

I think I've worked out why the timeline in For All Mankind is divergent -- no, it's not Korolev surviving his surgery. It's that their Moon is completely different from our Moon ;)

Seconded!

Starter packs are such a great way of getting your BlueSky community off the ground! I am so grateful for these as I rebuild from the ashes of Twitter. Here is a starter pack for female and other minority astonomers 🔭 put together by @kanaya-malakar.bsky.social : bsky.app/starter-pack...

I was today years old when I realised that NASA/ADS have deprecated the "^" for first author, and it's not just my internet connection.

An emerging class of objects in #RadioAstronomy, mostly discovered in the last few years, still can't be explained. Two new multi-wavelength studies might have answers. www.spaceaustralia.com/feature/mult... by @cosmicrami.com #SpaceAustralia 🔭🧪 📸 @colourfulcosmos.bsky.social /MWA/Curtin/ICRAR

Doing media interviews from home while looking after my sick kid... Yes, that's an outdoor trestle table from Bunnings 😂

Out now in @theconversation.com, I write about our discovery of the first long-period radio transient with an optical counterpart -- our first clue to the progenitors of this mysterious class of objects! theconversation.com/astronomers-...

Hope he covers circumzenithal arcs. My favourite kind of rainbow 🌈

Stunning yellow halo at the moment in Perth. Must be a mix of clouds and smoke to generate both the refraction and the eerie colours. Any meteorologists in my follows who can weigh in?

Out today in ApJL! Our discovery of the first long-period radio transient with a stellar counterpart: www.icrar.org/binarytransi... At least *some* of these objects might be explicable as binary systems!

Starting the day (and my timeline here) with the fantastic news that my Discovery grant proposal with Prof Nanda Rea has been funded by the Australian Research Council! Over the next three years we'll be investigating the mysterious long-period radio transients using telescopes around the world!
