I'll end with the last paragraph of the paper:

"In addition to the dangerously high collision risks calculated here, we are already experiencing disruption of astronomy, pollution in the upper atmosphere from increasingly frequent satellite ablation, and increased ground casualty risks. By […]

Braucht es wirklich noch einen Text, dass man jetzt wirklich nicht mehr auf #x aktiv sein sollte, wenn man Prinzipien hat, die #eu eher gut findet oder man die freiheitlich-demokratische Grundordnung für schützenswert hält?

Cool. My new book has been nominated as science book of the year. If you like this big story of our planet between big bang and apocalypse and you feel a bit Austrian today, you can vote for it wherever you live at https://www.wissenschaftsbuch.at/ […]

This is blowing up a bit: not trying to scare you all! There is a *gigantic* set of sunspots coming around the limb of the sun, comparable in size to the sunspots sketched by Carrington. They may or may not send some plasma our way. There is also a minor aurora event predicted for 2 days from […]

Every astronomer who complains about satellite streaks has heard the same response from techbro-types: "Why don't you just put all your telescopes in space?"

There are an incredibly large number of reasons why that is totally not going to work. But here's another from Borloff et al "Satellite […]

The sky isn't quite dark enough to see if there are auroras yet, but the fucking Starlinks are easy to see. Due to the Starlink main orbital shell configuration, there is almost always a Starlink or two visible crawling across the sky at the same elevation as the North Star (lots more in other […]

It's always great when your PhD student gets her first observing proposal accepted. Even better if it's with a fantastic score. But the icing on the cake is if you didn't have to do anything yourself to help.

Finally here! Two years after #nasa 's #OSIRIS-REx mission returned samples of #asteroid #bennu to Earth, we have now received 319 mg to study in our labs. We are hoping to determine Bennu’s isotopic composition and learn more about its “birthplace” in the Solar System.

Allerdings sind solche Modelle & Vergleiche aus unserem Alltag auch gefährlich: Sie sind keine vollständige Beschreibung der Wirklichkeit, das geht nur mit der Mathematik. Auch brechen sie recht einfach zusammen - es gibt z.B. keine unendlich dehnbare Folie. Manchmal können sie auch irreführend […]

Gedanken zu Wissenschaftskommunikation und (Wort-)Bildern aus meinem Buch:

Comet Lemmon (C/2025 A6) in the morning sky, just before twilight starts.

The camera was on a fixed tripod, no tracking, short telephoto lenses. 30 images were taken, then stacked with software.

This comet is faint to the naked eye, pretty in binoculars […]

I always feel such a weird mix of hope and dread after these meetings. Can we really stop companies from destroying orbit? I am very glad to see that there are a lot of really lovely, kind astronomers who care enough to spend their time fighting to save the sky.

Huh, I'm pretty sure this is the first time I've seen a real estate listing for an astronomical observatory. It's the Molonglo Observatory Synthesis Telescope, a radio telescope that operated between 1965 and 2023. Along with the remains of the telescope you get a […]
