Join us @sydney.edu.au for our 2025 Stibbs Lecture: "Reflections on the Discovery of Pulsars: An Evening with Dame Jocelyn Bell Burnell" Date: Thursday 16 October 2025 Time: 6pm - 7:15 pm Venue: University of Sydney Registration is free: www.sydney.edu.au/science/news... ⚛️ 🔭 🧪 #RadioAstronomy

Ever wonder what happened to that $100 million interstellar spaceship program? Me too. www.scientificamerican.com/article/the-...

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

One week left to apply for our continuing position in Applied Plasma Physics and Biointerface Engineering! A great opportunity for someone at Levels B/C/D (lecturer to associate prof.) to lead in this area. Deadline Sep 17th usyd.wd105.myworkdayjobs.com/en-US/USYD_E... #Physics #Engineering

For the last two years, I've been paying for the Astronomy feeds hosting myself. It has been a privilege to grow our community here, but I also shouldn't keep doing it for free 😅 That's why I'm delighted to announce that we now have a donations page on Open Collective! 🔭☄️ #astrophotography

Come and join us for the Dr Peter Domachuk Memorial Lecture on "Heat, Light and Passive Cooling" presented by Professor Shanhui Fan. Wednesday October 1st, 6pm @sydney.edu.au #Physics, followed by a cocktail reception. Registration is free: www.sydney.edu.au/science/news...

How are we feeling about the likelihood of clouds over Sydney at 3:30am? #Astronomy

Congratulations to @anitaho-baillie.bsky.social from @sydney.edu.au #Physics A Eureka Prize recognising her cutting edge research in solar cell technology!

Interested in owning a part of Australian history? The Molonglo Observatory site is for sale: www.realestate.com.au/property-hou... Don't worry, we stopped scientific operations a few years ago and gave it a suitable farewell (see next post). #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).

Senior software engineering position at CSIRO / SKAO / Data Central, based in Marsfield, NSW ...you will be instrumental in developing and supporting software components that enable seamless data access, processing, and analysis... jobs.csiro.au/job/Sydney%2...

Bluesky now platform of choice for science community - Ars Technica | Media coverage of our new paper

Writers/bloggers: What's your preferred platform (or which should I avoid)? I like/want: * Minimalist style * Impact but not monetization * Tech-savvy but want to spend time on writing, not tech * Writing, not videos :) What are your favourite science/academic blogs? 🧪⚛️🔭 #AcademicSky

Very interesting story by @rebeccacharbon.bsky.social about the start of global Very Long Baselline Interferometry (VLBI) #RadioAstronomy during the Cold War.

Results from the first part of our fourth LIGO @egovirgo.bsky.social KAGRA observing run are out today! We're pleased to share the largest catalog of gravitational-wave observations with more discoveries of black holes and neutron stars 📰 arxiv.org/abs/2508.18082 🔭🧪⚛️☄️ #GWTC4

The Australasian Dark Sky Alliance have created a petition to get the Aust. Govt to create legislation that limits light pollution and preserve Australia's Dark skies. Important for human health, wildlife and #Astronomy! Australians can sign here: www.aph.gov.au/e-petitions/... 🔭☄️

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. ⚛️🔭🧪

Quantum #Physics in the Pub! It’s the International year of Quantum, and researchers will be at the pub to tell you about the quirks of quantum physics: its history, its behaviour, and even its taste! 6:30pm, Tues. 26th Aug, Abercrombie Hotel. events.humanitix.com/physics-in-t... @aip.org.au

About to give the introductory lecture for my favourite course: "The Apocalypse in Science and Culture" @sydney.edu.au We introduced this course (unintentionally) in the middle of the pandemic. It proved to be a great way for students to process their experiences and concerns about the future.

Finally completed the Milky Way. Have spotted heaps of transients already :) #Astronomy

Congratulations to Professor Anita Ho-Baillie @anitaho-baillie.bsky.social - finalist in the Eureka Prize for Sustainability Research! www.youtube.com/watch?v=D305... #Physics

In the middle of a week of interesting talks on radio transients at Dynamic Radio Sky 2025. Is great to welcome so many people to @sydney.edu.au and @ozgrav.bsky.social for our meeting - and particularly all postdoctoral reseachers and PhD students. The next generation of #RadioAstronomy!

Science ethics question: If you're in a really boring university committee meeting, and you get distracted looking at astronomy data and make a new discovery, should you include the committee chair as a co-author on the paper?

This is great news for the SKAO project! #RadioAstronomy

Are you a top US-based scientist wanting to relocate to Australia? We are now calling for formal applications from both Australian and non-Australian citizens based in the US whose work is internationally recognised as exceptional. 📅 Applications close: Aug 29, 2025 🔗 science.org.au/gtap/?utm_so...

I had great fun asking @astrokatie.com all the hard questions about cosmology tonight @sydneyideas.bsky.social. Most unique question: "If cats and dogs could understand the end of the Universe, which would be most bothered by it?"

Congratulations to my former student Joshua Pritchard for winning this year's @astrosocaus.bsky.social "Emerging Leaders in Astronomy Software Development Prize" for his software package "DStools". Here's a short write-up: www.atnf.csiro.au/news/recogni... #RadioAstronomy

PASA is looking for two new Associate Editors - this could be a good opportunity for astronomy people looking for editorial experience. #AstroSci

The universe began with a Big Bang but what about its endgame? Will everything burn out and freeze over, or collapse in on itself, or rip into shreds? And how far away is this? Join us for a talk about the 5 likely ways the universe can die with @astrokatie.com, hosted by @taramurphy.bsky.social

@manishacaleb.bsky.social rounds off #skao2025 with the final plenary talk, on cosmology with fast radio bursts. #RadioAstronomy @ozgrav.bsky.social

Incredible showing from Australians past, present and future, at #SKAO2025 in Görlitz. All very excited about getting the first data from the SKAO telescopes! Aussie, Aussie, Aussie! #RadioAstronomy

@colourfulcosmos.bsky.social Natasha Hurley-Walker updates us on the mystery of long period transients at #skao2025 Are they magnetars? Are they white dwarf M-dwarf binary systems? Maybe some of each… #RadioAstronomy

Sydney radio astronomers (plus a bonus cosmologist) at SKAO 2025! It's great to be here with so many of our team :) @manishacaleb.bsky.social @astrolaura.com @cosmichorizons.bsky.social @ozgrav.bsky.social #RadioAstronomy #SKAO2025

Ah 8 bells, it must be 7:53am !

First night in Görlitz. There are church bells that chime every hour. And a single chime every 15 minutes. BUT there is also a bell that chimes 7 minutes early! So… 1:53am, 2am, 2:15am, 2:30am, 2:45am, 2:53am, 3am. View from my hotel window this morning. Is this the culprit? #skao2025
