I'm a scientist studying fluid dynamics in the cores of rotating planets and stars. I mostly post pics of clouds and timelapses. All media by me. He/him.

Cheesy sunset today. But the nacreous clouds did not return.

These pics show some clouds very similar to nacreous clouds (above the dark cloud band). This is about 20 minutes after sunset. Normally #nacreous #clouds form at high latitudes, but this is from Cartagena, Colombia, at only 10.4º latitude North. Any expert around knows if this is possible? 🧪 ⚛️

There was a nice atmospheric inversion layer when my flight took off early in the morning from Paris. Here you see dense fog on the ground that doesn't even reach the top of the wind turbines. The ripples are gravity waves created by the wind turbine towers as the wind blows. 🧪 🌬️

Models are great. Simulations are awesome. Synthetic data is useful.
But all of them can also be awful and used to generate bad science. We need to know exactly why we're using any of them, what assumptions we're making when using them, and what those assumptions mean for our inferences.

This is fucking grim. Somebody invented a white guy, an "IT professional" named Edward Crabtree, who stopped the Bondi shooting and spread it all over the internet, which was picked up by AI agents and slop aggregation sites.

All missions should have cartoon versions of their spacecraft, and these cartoons should be on all slides. These are the rules, as shown here by JAXA’s Go Murakami talking about BepiColombo.

As I say here, this is not about saving the planet. The planet will be orbiting the sun long after we’re gone.
The question is, will there be a healthy, thriving human society on that planet? The answer to that question is very much up for grabs at this point.

As a professional astronomer, I absolutely would not want my children going into this. I hope they have been clear witnesses to my ceaseless anxiety and job insecurity. Yes, funding is much worse now than a year ago, but academia has been a disaster for a LONG time
My teen, who had dreamt of being an astrophysicist, just told me he wants to go to law school because, “Science isn’t going to be a priority in the US in the future…I don’t want a job where I’ll be constantly worried my funding will be taken away.”
Gutting. How many future scientists have we lost?

I mean we are absolutely in a place now where the only solution to this information disorder is for everyone to constantly evaluate the source of information. Never trust a chatbot, but also don't believe a video unless you know and trust where it comes from.
Unfortunately... that's a lot of work.
