Sometimes when I'm quickly checking whether someone in my team has classified a #RadioAstronomy source correctly, I paste the coordinates into the Aladin Sky Atlas , and confirm... Yes, it is a star! Such a great #AstroSci tool :) (aladin.cds.unistra.fr)

Very happy to announce that our review of radio transients has now been published by PASA! bit.ly/3Yg3hyD Unlike most radio sources, transients change rapidly. My favourite bit are these lightcurve cartoons that show how different types of transients change with time. #RadioAstronomy 🔭 ☄️🧪

#RadioAstronomy of stars is a rapidly growing area of research as we discover more of them :)

I've had an amazing week discussing gravitational wave science (instrumentation, detection and cosmology) at our @ozgrav.bsky.social annual retreat in Melbourne. Here's our group photo from Carl Knox! #Physics + #Astronomy

Hey Murchison Widefield Array people - we now know an astronaut :) #RadioAstronomy

Hey, astronomers. Can you imagine astronomy research without ADS?!?!? No? So, have you filled out the ADS survey yet? Help archives help you! (Help archives keep funding!) docs.google.com/forms/d/e/1F...

I've been thinking a bit about how talking about aliens affects how we share new astronomy discoveries, so I wrote an article about it 👽🔭🧪 theconversation.com/is-it-aliens...

Huge congratulations to @manishacaleb.bsky.social for her successful ARC Discovery Project on "Tracing the origins of Long Period Transients in the Milky Way" and to @benjaminpope.bsky.social for his project on "Where are all the Exo-Earths?" Two exciting #AstroSci projects starting in 2026!

#Physics!

The #Astronomy Genealogy Project (AstroGen) is a cool @aas.org project that links all astronomers with their academic "ancestors" and "descendants" (via PhD supervision). Sharing because I discovered an astronomer that wasn't aware of it :) astrogen.aas.org/front/index.... ☄️

It was a privilege to attend our @sydney.edu.au graduation this week to see Dame Jocelyn Bell Burnell receive an honorary DSc in recognition of her outstanding contribution to astrophysics, advocacy for under-represented students and as an inspirational role model for women in science. ⚛️ 🔭 ☄️

When we search for radio transients we exclude extended objects Hence we discard lots of radio galaxies, like the ones in this ASKAP VAST gallery, compiled by PhD student Surabhi Chandra Each image shows radio emission from a galaxy with a supermassive black hole at the centre #RadioAstronomy

Participation in Australian high school #Physics is declining! The proportion of Yr 12 students studying physics fell from 14.9% in 2015 to 12.1% in 2023; gender ratio unchanged. (Luckily this hasn't impacted the number of students studying Physics @sydney.edu.au, but it is a broader issue).

New regulations are needed to protect #RadioAstronomy from satellite mega-constellations. We deliberately build our telescopes in the outback to avoid radio frequency interference (e.g. from TVs, microwaves, phones) but now unintentional transmissions from satellites are affecting images. ⚛️🔭🧪
