It is really wild to me, that one company has the power to do what it wants on a global scale, for its own profit ambitions, and no one regulates them properly. SpaceX Starlink is an unethical business model. A new study has shown that emissions from the satellites are harming protected spectrum.

A few general nuggets from the Astrostatistics summer school I keep hearing over and over again (and which I firmly agree with)..... 🧵

Congrats to the Netherlands on the fall of their government. 🥂

If you’re awake in the US and have clear skies: go outside—you might see some aurora!

Briefly wandered over to The Other Place to gauge the response to the NASA budget devastation to encounter a bunch of gleeful 'we spend too much money, so this is great.' TO BE, ONCE AGAIN, PERFECTLY CLEAR, THE BUDGET REQUEST MOVES ALL THIS MONEY TO DEFENSE. IT SPENDS IT. NO MONEY IS SAVED.

Many others are posting abt this too but this graphic viscerally shows how dire the presidential budget is for NASA 🔭🧪and worldwide astronomy. I can’t express how sad this makes me, as an American scientist. And it’s mostly already paid for projects, so also no logic in terms of saving money.

113 years ago one of the greatest experimental physicists of the modern age was born. Her name was Chien-Shiung Wu and in the 1950s her lab was the gold standard in experimental rigor, demonstrating in 1957 the non-conservation of parity. tinyurl.com/58ajh4ys #WomenInSTEM #Physics 🧪

Here's the NSF summary of major facilities, some astro changes noted. nsf-gov-resources.nsf.gov/files/00-NSF... 🔭📡🧪 VLA: "Very Large Array and Central Development Laboratory will operate at reduced levels of service at the FY2026 Budget level" LIGO: "NSF will operate only one of the two sites" 1/2

How does radar work in weather forecasting, and why would it be such a big issue if your local system went down? 🧪 www.scientificamerican.com/article/how-...

Made a cocktail for my wife and she put it in the freezer, inadvertently creating a new superorganism please hel—*glurk*

We were hoping that this letter to @bsky.app could first be shared by a Gazan, but we were too worried that doing so would get their account deleted so we are sharing first. You can sign on to the letter about the unfair treatment of Gazans on Bluesky here: docs.google.com/document/d/1...

Absolutely stunning mural by street artist El Niño de las Pinturas at the Instituto de Astrofísica de Andalucía. I loved seeing his work around Realejo when I lived here. Seeing this new mural at my former work makes my heart happy.

Happy Pint of Science to everyone around the world! Find a science 🧪 talk in a pub near you between now and Wed: pintofscience.com

"How simple and frugal a thing is happiness: a sunny day, a lush forest, the sound of the sea, a 25 m radio telescope... All that is required to feel that here and now is happiness is a simple, frugal heart." – Adapted from Nikos Kazantzakis

this is a letter to the editor from a high school track runner who came in second to a trans girl in a race. her state house rep in maine started talking about it. so she wrote this: www.pressherald.com/2025/05/14/r...

Press release from Chalmers: "Sweden joins two giant telescope projects" www.chalmers.se/en/current/n... Yay! 🔭📡

Choose Science. Choose Europe. A new Marie Skłodowska-Curie Actions Postdoctoral Fellowships 2025 call is now open. With a budget of €404.3 million, it will support around 1,650 researchers from Europe and beyond. Apply by 10 September → europa.eu/!fBTMgF

I really hope one of Google's rival will tackle Google Business profile. The main reason I stillmkeep google as a backup is to quickly get contact information and business hours of places. #Qwant #DuckDuckGo #Ecodsia

Seems like the perfect time to change the default search engine on your phone and laptop. I’m currently using Ecosia (laptop) and DuckDuckGo (phone), but I think the future could be www.qwant.com

Just discovered our fav beer and pizza joint in Gothenburg, Sweden has a New Glarus Brewing (Wisconsin) sticker! ❤️ Also Uiltje.

SO CUTE. Listen as kids explain what their scientist moms do at the Smithsonian Natural History Museum 💚 #MothersDay

And website is working again…still going…heading for Europe.
