Can empty space alter the behaviour of light? Turns out the answer is seemingly yes, if you have a magnetar on hand! Using NASA’s IXPE and NICER telescopes + the CSIRO’s Murriyang radio telescope, we may have finally detected this effect 🔭 🧪 ☄️ Publication in Nature: www.nature.com/articles/s41...

Shuang Yang—Chang’e 7 will land near the Moon’s south pole Shackleton crater later this year and deploy (via tether) a seismometer that is planned to survive for 8 years. This might be the first node of a long-lived *international* geophysical network! #AOGS2026

Ralph Lorenz—Huygens showed that Titan can be wet, even at low latitudes. As Dragonfly flies across Titan, the odds it’ll land in mud are low (<1%), and if so, the stickiness will be again to sticky wheat dough (and Dragonfly could still takeoff). #AOGS2026

I am a big fan of @jtuttlekeane.bsky.social science sketches!

Christos Ntinos—Developing a new “super resolution” Cassini VIMS map of Enceladus. The map can provide insight about physical properties (grain size, crystallinity, etc.) which are useful for both science and future exploration—like the ESA L4 mission concept. #AOGS2026

We've discovered two more long period transients! A new @pasajournal.bsky.social paper by Yuanming Wang and collabs introducing the VASTER pipeline running on ASKAP. As soon as we switched it on we started finding new things (star and LPT below) dx.doi.org/10.1017/pasa... #radioastro ☄️

Thank you for this correct opinion, @anildash.com! This is my fav George Michael song ..... EVER. Also Fastlove samples the catchy: "baby, please, forget me nots" by Patrice Rushen. which is also the same melody used for: "here come the men in black" from the Will Smith film.

Anil Dash@anildash.com · yesterday

Many people don't know the best single that George Michael ever released, or rather the best _version_ of his best single ever: the Fully Extended Mix of Fastlove Part II. At 3:55, he introduces a new verse, soon his vocoder shows up, and then we're off to the races. www.youtube.com/watch?v=lP6O...

Elon Musk repeatedly one-upped his execs on SpaceX’s first earnings call

Very very very Rupert Murdoch world domination vibes. 🚩 HT @lorak.bsky.social on CNBC live blog: www.cnbc.com/2026/08/04/s...

Musk claims SpaceX has "solved" the "heat shield problem" for Starship after latest flight "I would say that we do not see any technical obstacles at this point to achieving full and rapid reusability" Heck of a claim with a few broken tiles and no explanation of how SpaceX will refurbish them

A trillion dollars revenue by 2029, for a company that is not making an anywhere remotely close to this on a projection in 2026. That’s some quality, 5D chess master maths right there.

Sean O’Kane@okane.fyi · yesterday

We're in full SPAC-era territory here. Musk: "Prior to the IPO, the financial projections we had were reaching a trillion dollars in in revenue in 2031. We now expect that to be in in 2030, and there's a non-zero chance of that being in 2029."

Loooooooooooooooooooool. What does this even mean? But how is it even measured, or projected? What evidence is there for these sorts of claims? Christ. The richest man in the world is also one of the dumbest.

Sean O’Kane@okane.fyi · yesterday

Musk, whew: "If you have a mass accelerator on the moon, and you have solar and radiator production on the moon, you can -- I know this sounds totally nuts -- but you can probably scale to 1,000 times the economy of Earth in terms of intelligence launched to space, maybe even 1 million."

Sean’s got you covered for #SpaceX earning call 👇🏽

Sean O’Kane@okane.fyi · yesterday

Elon Musk spending SpaceX's first earnings call focusing on the tangible stuff, like how he thinks Starlink "will deliver a majority of the world's internet"

This is how my day started. Woke up, let the dog out back, grabbed a glass of water, casually checking BlueSky, then BOOM — read this headline/post from Playboy, who are absolutely not holding back. lol. Imagine reading that Playboy called you this. Ooooft. (and to answer the question: yes.)

Playboy@playboy.com · yesterday

As they amass more money and power, the public views billionaires as sweaty psychos Scrooge McDucking their way into evil amounts of cash. The collective ick emerging raises a question that wealthy men might prioritize over ethical perceptions: Have billionaires become categorically unfuckable?

These systems are rare but very useful: the rotational stability of millisecond pulsars (think: very accurate, stable clocks) allows astronomers to perform very precise tests of gravity in three-body systems and to consider how these systems came to be through their evolutionary formation.

👀👀👀 Ohhhh, this is very exciting science! 🔭 Two independent papers are reporting updated details of the PSR J0435+3233 system: it's a triple! Features a millisecond pulsar + a helium white dwarf and now a Sun-like star. arxiv.org/abs/2607.27462 arxiv.org/abs/2608.01227

This is pretty much my BlueSky vibe 👇👇👇 If your only source of politics, or any global issue, is a social media platform, then that's your problem. If you think that people should be subjected to "other side" views to broaden their horizons, then I'm going to deem you an extremely online person.

"Bluesky is a political echo chamber" okay but I'm mostly here to chat with fun internet people and post art and make jokes, I cannot stress how much I don't care

oh that's right ... at some point later today, is the #SpaceX second-quarter results. And a portion of the lock-up restrictions expire as well I think. 🍿🍿🍿 <checks on share price> .... it's a thing of mathematical beauty. Shall we fit a model to this?! Let's see how it reacts to the report.

I'm extremely proud of @breaky.bsky.social winning a Tall Poppy Award for her science and communication in Queensland! She's of three astronomers recognised this year - alongside the excellent Fiona Panther (WA) and Laura Driessen (NSW)!

I am a radio astronomer that intercepts radio signals from space in my day job. I would totally follow any instructions received from space, whip up a batch of ET goo, and very likely lick it. For science!

In 1999, the Lunar Prospector orbiter was deliberately crashed into Shoemaker Crater at the Moon's south pole. The spacecraft carried some of the ashes of legendary planetary geologist Eugene Shoemaker. 🔭 🧪

NASA's Lunar Prospector orbited the Moon for almost 19 months to map its surface composition and to look for polar ice. The probe found evidence suggesting

On August 5, a SpaceX Falcon 9 rocket is predicted to crash onto the Moon. What has crashed on the Moon before? The very first human object to touch the Moon - Luna 2 in 1959. A probe, 3 bombs, and a rocket body! 🧪 🔭

A lovely little bit of physics that you might have spotted if you ever play with a slinky. We should all play more, because we should all embrace our curiosity. And finding out how the physical world works is fun!

With Jodrell Bank in the news, remembered this photo that was taken in 2019 for Apollo 50th.

CosmicRami 🏳️‍🌈🏳️‍⚧️@rami.spaceaustralia.com · last yr.

Have just been reminded of this photo: 6 years ago today! Was the 50th Anniversary of Apollo 11. @drspacejunk.bsky.social was at @jodrellbank.bsky.social observatory, and I was on the other side of the world, at the CSIRO Parkes radio telescope (Murriyang). Looking out at two great telescopes!
