If the idea is correct, then somehow the theorists are going to have to figure out how to get coherent emissions from outside the polar cap (which is gonna be fun). But if so we should see more MSPs!

Of course, MSPs have to just go and get more complicated for everyone ....

Some really interesting ideas here (pre-print) from Michael Kramer and Simon Johnston (SJ works with us!).

Unlike the conventional concept of radio emissions in millisecond pulsars coming from polar caps, could they also be coming from regions where gamma-rays are emitted?!

Radio emission from beyond the light cylinder in millisecond pulsars

A striking aspect of the radio profiles of many millisecond pulsars (MSPs) is that they consist of components separated from each other by regions lacking in emission. We devise a technique for determ...

This is why I keep saying we must never forget and never forgive the people who did this to us.

We have to learn from the failure of Reconstruction, and punish them, so it never happens again. We can't let them just move on, and pretend that they never did any of this.

Always remember that it was not only Trump, Musk and all the evil minions that work with them that did this …. But also all the disgusting MAGA people who voted for this to happen.

Horrific reporting from the AP on the Myanmar families watching their kids starve to death from Trump and Musk’s aid cuts apnews.com/article/myan...

Starving children screaming for food as US aid cuts unleash devastation and death across Myanmar

U.S. Secretary of State Marco Rubio has repeatedly said “no one has died" because of his government’s decision to gut its foreign aid program.

I'm sorry to hear that. They're resilient, so he will stay mad for a bit but then be ok.

You're def. making the right choice here - I would not do that trek unless I was with a fully supported local team + ensure my medical access was good. Way too many risks IMO, esp. for a young person.

CosmicRami 🏳️‍🌈🏳️‍⚧️ @cosmicrami.com · 13h

From someone with a bit of experience hiking more challenging environments, I think your choice is sensible. I've even considered doing it but also opted for easier treks, esp. post my Vietnam experience.

Would he consider Queenstown or Tassie instead? Good trails there IMO.

My own experience of this was caving in Vietnam. When we were above ground, the humidity is so strong that carrying any weight on your back feels like it is several times heavier.

Plus, you gotta watch footing, watch out for leeches, mozzies, even plants that cause extreme pain if you touch them.

It's not an easy walk. I've not done it, but have done several high mountains, and met people along the way that have, and every single person I have encountered have said it is extremely challenging.

Unless you are from the tropics, you underestimate how hard the humidity is on the body.

Often play a game with my dog where during our walk, I run off and leave him behind and head to one of the swing sets at the local playgrounds.

Once he realises what is happening and I am on a swing, he loses his shit.

Not exactly sure why he hates me on the swing — but it’s always funny!

Weirdo!

It was cloudy last night, so this is not the Harvest moon/super-moon, but instead the full moon from last month just before, and during, the total lunar eclipse.

September full moon just before the total lunar eclipse. The crater Tycho is at bottom-centre.

Interested in research based on our archive data?

Then the ESA Archival Research Visitor Programme might be for you.

The next deadline for applications is 10 November 2025. Check out all the application details here 👉 www.cosmos.esa.int/web/esdc/vis... ☄️ 🧪 🔭

Illustration promoting the Archival Research Visitor Programme and the next deadline date of 10 November 2025. In the background, a model image of what our home galaxy, the Milky Way, might look like face-on: as viewed from above the disc of the galaxy, with its spiral arms and bulge in full view. In the centre of the galaxy, the bulge shines as a hazy oval, emitting a faint golden gleam. Starting at the central bulge, several glistening spiral arms coil outwards, creating a perfectly circle-shaped spiral. They give the impression of someone having sprinkled pastel purple glitter on the pitch-black background, in the shape of sparkling, curled-up snakes.
