Thanks Rami! Someone told me a really good idea: they asked a local astrophotographer to take a photo of the night sky on their daughter's bday and gave that as a gift. Supports a local astrophotographer, is lovely and meaningful, and not a rip off!

Sydney queers & friends! If you're about for the #SydneyMardiGras festival, come along and join our @queersinscience.bsky.social team at a social mixer on the 27 Feb in Surry Hills. FREE EVENT but rego req. I'll be there and am happy to talk your ear off about pulsars and Pedro Pascal's hotness.

New protein shake mixer arrived (it’s good!) so naturally I had to make a water tornado! I love staring into these things and thinking about how the plasma-filled magnetosphere of a pulsar co-rotates along with the star itself. Mind boggling for the millisecond pulsars! 🧪

This is the way! This is resistance and shows the haters that we're not gonna just sit by and let them try erase queer people! #LGBTIQA+ 🏳️‍🌈

Good piece from @astrolaura.com about grifting that is "buying" stars or star names. Don't do it. Go chat with your friendly astronomer pals - they have many names for the stars they study, and if you ask about a certain star they study, maybe you can come up with a name they'll use! Save $40!

Not one, but TWO sea puppies in the harbour near our place today! What a treat! Overcast day and murky waters so cropped images aren’t that great but I’m glad I got to see our little friends feeding and doing their thing. A sign of a healthy ecosystem. Stingrays are so cute!

Lolzy at the epic ratio on this post. Tl:dr — a Deutsche Banak analysis thinks Intuitive Machines (#$LUNR) is a good investment because they will build infrastructure on the Moon. Based on: - Musk declaring Lunar “self growing cities” - Bezos’s space tourism winding down for Moon-mission focus

***Strong Content Warning on non-autoplayed video in this story: extreme animal cruelty*** This is absolutely shocking. New legislation requires the QLD Dept. of Primary Industries to 'approve' prosecution cases of animal cruelty. Cases significantly fallen. www.abc.net.au/news/2026-02...

"This process is also open to those outside the United States who may be impacted by a proposed system." Thank you @aas.org! It's *important* that global communities are able to have a say in a global commons - the sky we all share. USA FCC granting spectrum allowance for 1M impacts us all. 🔭

I really *love* when we get these conjunctions! Depth is hard to perceive when looking into the cosmos, but images like this give us an idea. Comet - our Solar System Stars - further out, but our Galaxy Galaxy - very far away with a void between Looking across space & time! 📸 Daniele Gasparri

This is a real timelapse video of the Moon transiting in front of the Earth. It was captured by the Artemis 1 Orion spacecraft in November 2022 while flying at it's furthest point from the Earth. The video covers about 3.75 hours of real time. 🔭🧪

As part of the #Sydney Mardi Gras festival, QueerScreen (the queer film festival) starts today! Pillion is on tomorrow night for those that want to catch it! This Sunday is also Fair Day (a big queer fair in the park with tens of thousands of people - little mate and me might go!) #LGBTIQA+

Omg omg omg omg …. Anyma is bringing his show to Sydney! Oct 17 in The Domain!

Neato and one for my #AvGeek pals! Check out UA1656 over the Caribbean en route to Cancun from Chicago on 9th Feb. The catch? This image was taken from orbit by one of the HEO (Aussie company) cameras! 📸 Williame Crowe (HEO CEO and pretty awesome dude) - shared with permission.

A fun paper on arXiv today 👇 Idea: send out five radio telescopes into the system to get baselines of 10s of AU, and use them as a 'Cosmic Positioning System' to triangulate positions of incoming event (like FRB) wavefronts. And these illustrations and font FTW! 👏 arxiv.org/pdf/2602.09141 🔭📡🛰️

Spectacular #Sydney Sunrise. Go look!

A decade since I got to update havewedetectedgravitationalwavesyet.com ! #GW10Years

I know this is not the point of the post (and sorry for the tangent) but look at those teeny tiny two planets orbiting pulsar/s. They have extremely low mass compared to all the other exoplanets. Testament to how precise pulsar timing can be - we can spot the poor planets orbiting these bastards.

That's our spaceship! 🌏 In the near future, four humans with much more advanced cameras are going to be able to take new photos of our world from similar distances (and further!)

On International Day of Women and Girls in Science, we asked the #WomenOfDarkMatter what inspired them to pursue their studies in physics. 🧪

Far out, that story on the usage of the thermobaric weapons in Gaza is harrowing. Like the worst horrors in history kinda stuff. I thought those kinds of weapons were prohibited. That's 100% war crime action. Going to await further sources on investigating / reporting it as it is one source only.

I have this indoor plant at home that always tells me it’s sad and needs more water. It’s high maintenance and needs to be watered once per week! But when it does, it goes from “please sir, can I have some more” sad face to happy face! (mutuals — you might see your books on my bookshelf!)

Bad news for Trump: These colors don’t run.

Still laughing at this very unserious article. Musk has literally given every space journalist an opportunity to critically tackle his bullshit, and ask tough questions. Strike while the iron is hot. But no .... heaven forbid, someone upsets the Emperor. This reads like Elon Musk's sock puppet.

The people who work for #Palantir that are "concerned" about their company doing bad things (after happily taking the money for years) are just like someone who works at an abattoir and becomes "concerned" about the cows crying and screaming in the line as they're forced inside the machine.

Here's the memorandum, signed by Acting Director of NPS Jessica Bowron on 21 Jan 2026. You would think that these flags would fall under the excemptions given ... oh I don't know, it is called "the Stonewall Riots" .... but naaaaa, they just removed them. home.nps.gov/subjects/pol... #LGBTIQA

I already knew who this article author was going to be even before clicking on the article. Standard operating procedure for him.

And going back further (about a year ago when he just came into power) they scrubbed the word "Transgender" from the Stonewall website. These are not random events. These are systematic, well-timed and strategic attacks on queer people by this Administration. It all always starts with queers.

Of course, this is just the next messed up thing in a long line of events that this Administration has been undertaking that can only be summed up as hatred towards the queer communities. About 8 months ago, they enforced the removal of the Trans+ flag and the Progress Pride flag.

woah, this is kinda fucked up (but on brand). The Trump Administration ordered the National Parks Service (which manages momument locations like the Stonewall Hotel) to remove the Pride flag. This is the birthplace of the queer revolution movement! #LGBTIQA

Do not speak ill of my dear potatoes ever again! The little clump of starchy goodness is so versatile (hot chips, wedges, crisps, potato salad, mash, potato bake, potato and leek soup, hash browns, gnocchi, etc.) Potatoes are friends. Unlike celery which wants to make you a vampire!

Very happy to advertise a Postdoctoral Research Associate in Exoplanet Science position with me and Christian Schwab at Macquarie University in Sydney. We'll be working on applying machine learning & differentiable physics models to extremely precise radial velocity surveys.

Update on the post below: in a letter sent to Chile's Environmental Assessment Service on 6 February, AES Andes requested the withdrawal of INNA from evaluation. This formally confirms that INNA is not going ahead. 🔭 🧪

Checking out the #AstroSky cluster on this tool! I actually love the little satellite communities and how they all bridge and connect with each other. BTW - this is not a popularity contest! Your position and closeness to those around you doesn't make you better or worse! We're a big village! 🔭

You have to treat *every single thing* that Musk says about SpaceX for the next few months as suspect, because he is inflating the story of the company prior to the IPO. He wants people to believe this company is going to be Earth's saviour. All the evidence so far about them says otherwise.

Look, I might not be in the USA, but from ~15,000 km away, even I can see that the "things that will make people super happy and excited" would be ... oh I don't know .... .... sending their kids to school and not worry about them getting shot in the face .... a working healthcare system Bigtime.

🔭 Today’s exciting reading!

👀👀👀 Ohhhhhhhhhhhhhh This could be extremely exciting! 🔭

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

Yes! I was looking at the footage last night and they all look the same as those neo-Nazi dickheads. I was pondering if this is a police regulation thing (like no facial hair except for a moustache) but have def. seen cops with beards in the past.

How do cops ever want any community to trust them when the cops are the actual baddies? This is disgusting. The guy clearly had his hands up, was presenting no threat and did not provoke anything for 3-4 of these guys to start laying into him like he was a punching bag.

There’s going to be a whole lot of politicians and high-level officials in front of the cameras today after the really disturbing and disgusting behaviour of the Police at yesterday’s protests. I dunno, but inviting a guy who signs his name on bombs, is gonna kinda trigger people 🤷🏼‍♂️

1:30am finish from work and I still couldn’t solve the complex thing I was working on. Have been trying for days. Have to give up to get some sleep. On top of this, utterly distressed with police brutality on Sydney streets. Honestly, on some days, doing a PhD in all of this chaos is so brutal.

There's an unmarked military/govt chopper that keeps buzzing around, and I can see its lights out of my window and hear its annoyingly loud blades. Suspect it has to do with the huge protests going on in town or the international visitor (Isaac Herzog - who the protests are about) 📸 Flightradar24
