I have a really nice (horrifying) image stack that one of my research team members made, that powerfully demonstrates what a huge problem satellite streaks are for wide-field imaging. This is a 3 hour stack of star-subtracted 5 minute exposures using the Canada-France-Hawaii Telescope. The short diagonal lines are asteroids. The long diagonal lines are sunlit satellites that passed through the field of view during the exposure.

I have said and will continue to say most people have zero idea what it's like for scientists in the US right now.

We sat at an outdoor table the other day with a brilliant older queer scientist friend and ran into several scientist friends including one who worked at govt agencies on science funding. It is like having conversations after an apocalypse. So many people lost, labs folded, international postdocs gone, lines of work canned. DEI work going undercover, forbidden words erased

Don't worry, Sam, SpaceX won't ACTUALLY launch 7,000 satellites! (There are currently 10,296 Starlink sats in orbit)

Don't worry, SpaceX said they'd get their satellites fainter than magnitude 7! (They have not https://ui.adsabs.harvard.edu/link_gateway/2025MNRAS.544L..15M/PUB_PDF)

Don't worry, they won't actually start Kessler Syndrome! https://outerspaceinstitute.ca/crashclock/

Don't worry, they won't actually launch a million AI data centres into orbit!! https://theconversation.com/a-new-space-race-could-turn-our-atmosphere-into-a-crematorium-for-satellites-276366

(.) A billionaire death cult has its fingers around humanity’s throat. It both causes and downplays our existential crisis. The oligarchs are not just a class enemy but, as they have always been, a societal enemy: a few thousand people can destroy civilisations. It’s the billions v the billionaires, and the stakes could not possibly be higher.

Prof Stefan Rahmstorf says the chances of a shutdown look like “more than 50%”. We could pass the tipping point, he says, “in the middle of this century”.

So why is this not all over the news? Why is it not the top priority for the governments that claim to protect us from harm? Well, in large part because oligarchic power has championed a model of #climate impact that bears little relation to reality (..)

A catastrophic climate event is upon us. Here is why you’ve heard so little about it

Scientists say a crucial Atlantic system is set to collapse. But the billionaire death cult that steers humanity’s destiny just doesn’t do existential crises, says Guardian columnist George Monbiot

De Tweede Kamer der Staten-Generaal heeft een duidelijke lijn getrokken: het DigiD-contract met Solvinity mag in 2028 niet worden verlengd als het bedrijf in Amerikaanse handen komt. Een motie van Kamerlid Kathmann en medeondertekenaars kreeg daarvoor een meerderheid.
