Are you ready to read about nuclear arsenals & operations? Of course you are! I explore the modern risks of nuclear war, from AI to misinformation, for @nature.com. Thx to many experts including @mattkorda.bsky.social @cosmicpinot.bsky.social for this one. www.nature.com/articles/d41... 🧪

A wee thread on a paper I think has big holes and some suggestions for grad students out there looking for a fun calculation... (Technical) 🔭 🧪 #cosmology It's this one; it claims at least 1% of the photons in the CMB are actually generated in early-forming galaxies. 1/N arxiv.org/abs/2505.04687

🧵 Here is MoM-z14, the most distant galaxy spectroscopically confirmed to date. It is an extraordinarily luminous galaxy, discovered by a research team using #JWST, which has broken its previous record. Research paper➡️ arxiv.org/abs/2505.11263 🔭 🧪 #science #cosmology #Webb

People we need to encourage PBS to post on bsky. Wise dude be he. @cosmicpinot.bsky.social “I look around& I am scared,” Schmidt said. “The Australian government investment in its sovereign research capability was 50% higher 15 years ago as a fraction of GDP.” theconversation.com/nobel-laurea...

The first of millions! The Subaru Prime Focus Spectrograph (PFS) has begun science operations, and I had the pleasure of leading the first night’s observations of the 360-night Strategic Program. ~2000 high-z galaxy spectra exposure, in 0.6 arcsec seeing! #cosmology 🔭🧪

The Astronomy feeds now include 11 (!!!) brand new specific subfeeds! 🔭 The subfeeds try to cover every part of astronomy research with at least one feed. All subfeeds automatically crosspost to the main Astronomy feed, too! Here's a thread with links to all of them ⬇️

@cosmicpinot.bsky.social any chance you can boost the signal on this? The one thing I do know is that you are not ARC Tracker!

Looks like Comet C/2024 G3 ATLAS’s days may be numbered… the comet has faded & may have broken up post-perihelion as the nucleus fades from view, leaving a ‘tail-less wonder’ crossing the sky. Here's a great parting view w/ESO’s Paranal Observatory by Yuri Beletsky: www.instagram.com/p/DFF3LKtpIz4/

Professor Ute Roessner AM FAA has been appointed as ARC CEO by the ARC Board. They are Pro Vice-Chancellor, Research, at ANU at the moment. Their appointment starts 31st March and lasts for 5 years.

Comet G3 is getting exciting! Here it is from my back porch overlooking Toowoomba just an hour after sunset. 110mm 26x4s

Oh come ON now. This new JWST image is just ASTOUNDING. I feel like I’m falling looking into it, and that I would fall forever, and that I would enjoy it. NASA, ESA, CSA, K. McQuinn (STScI), J. DePasquale (STScI)

Congratulations Prof Natarajan!

Here is a historical research piece that combines a story about astronomy, art, history, and racism - it's both interesting and a highly enjoyable read. Thanks to Frank Bonjourno to pointing it out. www.lrb.co.uk/the-paper/v4... 🔭🧪

I live a 100km inland from the ocean, and we live at this time of year for the seabreeze- called locally the easterly. Today the wind turned from W to E, the dewpoint rose from 9 16C within 2 minutes, and the temp fell from 30C to 21C. The air smells of the sea, and becomes hazy.

a perfectly clear day from sunrise to sunset today - broke my all time record for solar production (92kwH) today as I was able to use all of the production and not ground it (had to fully charge the car!)

I have a battery partially paid for by the NSW govt which, for the first time, was discharged remotely during a 'grid event' between 6.15 and 7.15pm today. Interesting to see the technology in action.

We have started inducting the 2023 Australian Academy Fellows - congratulations to the new Fellows 🧪

⬆️ soil H2O content & ⬆️ CO2 lead to ⬆️ isotopic discrimination: Soil moisture effect not influenced by CO2 level & vice versa. Changes in carbon isotope record of terrestrial organic matter preserved in geologic record are best interpreted as deriving from changes in atmospheric CO2 🧪⚒️

Most of the time, the stars look the same from night to night. Sometime over the next six months, though, there's a good chance you'll see a new bright star in the constellation Corona Borealis! (I've simulated the before & after view here.) blogs.nasa.gov/Watch_the_Sk... 🔭🧪

Woot! LISA is gonna fly!! 🔭🧪 Gravitational waves from million solar mass black hole binaries!! And white dwarf binaries… which are ok I guess… 😉

I never met Arno Penzias, but the discovery of the CMB definitely catalysed a revolution in cosmology www.npr.org/2024/01/24/1... 🔭🧪

Fellow Astros, the General Assembly of the International Astronomical Union is in Cape Town this year 😍 👇Worth a follow as they announce the Symposia. 🔭

Do all the reviews you want, but the bottom line has been obvious for 10+ years. "We urgently need publicly funded scientists doing essential research for overall public benefit & a nice social media strategy doesn’t make that happen – funding does." www.theguardian.com/business/202...

should I be worried by this cross promotion?

Important and scary new paper on satellite megaconstellations: we may be creating a conductive band of plasma dust around the earth arxiv.org/abs/2312.09329

⭐💥🥰 Beautiful image, @danmil.bsky.social + team! Look at all that milky, smoky stuff ... that's synchrotron radiation - charged particles spiralling around magnetic field lines! Cass A is also an extremely bright radio source, reported as early as the late 1940s from memory. 🔭🧪

seems quite remarkable. any expert commentary my astro friends? 🔭

🔭Hermann Wehner has passed away peacefully in Canberra at the age of 99. Hermann was a talented engineer who arrived at Mt Stromlo in 1952 and worked at MSSSO and the AAT until nominally retiring in 1989 here is a 2014 interview openresearch-repository.anu.edu.au/handle/1885/...

Look who I found at an ANU alumni event in Los Angeles today!! Always a pleasure to catch up with my favourite Nobel-prize winning ex-supervisor. 😉😂 @cosmicpinot.bsky.social

This year’s Nobel Prize has been awarded to Katalin Karikó and Drew Weissman, who are the inventors of the Covid-19 mRNA vaccines, a discovery that has saved millions of lives. Congrats!
