Perhaps if the Herzog protesters had turned up dressed as Nazis the cops would have left them alone

Pushing and injuring a prominent MP who clearly identifies herself as such and who is filming peacefully is the sort of thing you can only do if you expect impunity

'Unfathomable state violence': NSW Police set upon Muslim prayer group, protesters at Sydney rally Muslim groups decry 'shocking abuse' of peaceful worshippers

Muslim organisations and civil liberties groups have slammed NSW Premier Chris Minns after NSW Police threw punches, used pepper spray, charged into pro-Palestine protesters and forcibly broke up a Muslim prayer group outside Sydney Town Hall yesterday.

The Town Hall Police Riot needs charges laid against cops who attacked protesters and resignations at the top. A total disaster for social cohesion

There continues to be a lot of conversation on how astronomers and researchers must “deal” with the existing and incoming pollution caused by satellite constellations.

But I want to see this reframed into asking:

“Why do these companies need this many satellites in orbit?”

Every wondered how we know that supermassive black holes are so supermassive? Well one trick is to watch how light echoes around them, using "reverberations" to map how big they are. In my latest paper I close out the Australian Dark Energy Survey (OzDES) to measure the masses of hundreds of SMBH.

They really need a train station in Bondi

Genuinely I don't understand why this government is trying to dismantle science locally when it's at its most vulnerable point globally. Like, what on earth are they trying to achieve. What's the endgame here. What's the constituency for just vandalizing expensively built societal infrastructure

I was very excited to receive a 𝐇𝐢𝐠𝐡𝐥𝐲 𝐂𝐨𝐦𝐦𝐞𝐧𝐝𝐞𝐝 𝐀𝐰𝐚𝐫𝐝 at last night's Queensland Women in STEM awards at the Queensland Museum.

Congratulations to all the other award winners and finalists, it was a privilege to be recognised among such an incredible group of leaders in science!

Very excited to be a finalist for the Queensland Museum’s Women in STEM prize, and very honoured to be named alongside such amazing women (like the fabulous @alicetwomey.bsky.social) 👩‍🔬🔭

Check out these fun stickers I made for the Centre for Astrophysics and iLAuNCH! Both are drawings of University of Southern Queensland's Mt Kent Observatory (Queensland's only professional observatory!).

p.s. if you want a sticker I have a stash with me, and in the Astro lounge on campus 🤫

USyd felt like a fan-forced oven when I was biking earlier! 🥵

Yay Tam! Couldn’t have gone to a more deserving person.

Come and see @unisq.bsky.social astronomers talk and do some Space Trivia at Bribie Island RSL at 11am on Saturday!

Logo for sprigs is a wattle where each flower represents a different subfield, e.g. exoplanets or asteroseismology.

Lovely to see my art out in the world! I made this fun logo for the Stellar and Planetary Research in Greater Sydney (@sprigs.au) group. How many subfields can you spot in the flowers?

greta ily what an outfit

It’s Friday night.

I’ve done enough this week.

You’ve done enough this week.

** correction.

This is a daytime event - running from 11-1pm!

Super happy about this paper today led by the brilliant @astroshashank.bsky.social - equations and information theory about what an interferometer really encodes about a stellar surface.

My fabulous student, @elocinimages.bsky.social, is organising Space Bar - an astronomy night on Bribie Island, hosted at the RSL. Come along to hear from @unisq.bsky.social astronomers, do some space trivia, and maybe win a prize ✨

Gaza Sumud flotilla: How Israel breaks international maritime law The Global Sumud Flotilla says its fleet of over 50 ships has entered the ‘high-risk zone.’

The Global Sumud Flotilla says its fleet of over 50 ships has entered the ‘high-risk zone.’

If LLMs are widely being used to give legal, medical, and financial advice, why are they not being regulated accordingly

The March for Humanity across Australia should be a wake-up call for politicians who refuse to take action to end the genocide.

Thousands of people from all walks of life demanding in historic numbers that the government sanction Israel. Labor cannot - must not - ignore them.

I’ve seen estimate of 100,000-300,000 people in today’s march. A sobering thought: these are also the conservative (100k) realistic (300k) estimates of people israel massacred in Gaza.

Be there, Sydneysiders!

Just put out an article in @aunz.theconversation.com explaining this beautiful JWST image:

What is the Eta Aquariids meteor shower? And where and when can I see it in Australia? This display caused by Earth passing through debris from Halley’s Comet will be most visible on Wednesday – but only if you’re up before dawn

Come for the meteors, stay for the Milky Way!

Was very fun to speak to @caitlinecassidy.bsky.social about meteor showers and the night sky ✨

Foundation (TV) is really good but I cannot get past “Math” 🫠
