ESA appears to have suffered a data breach. The agency has said it is aware of the alleged security issue and that a forensic analysis is currently ongoing. Additional information will be released once the analysis is complete.

Meanwhile Europe: "yeah you know no one wants those cars. So maybe after 2035, we will stop selling ICE cars"

My family doesn't often tolerate my "fun planetary facts," but today's "did you know that the tallest mountain on Venus is covered in condensed heavy metal snow" did produce some interest

Amazingly, reaction times using screens while driving are worse than being drunk or high—no wonder 90 percent of drivers hate using touchscreens in cars. Finally the auto industry is coming to its senses.

Au fait à quoi servent les terres rares pour l’IA ? Quels éléments pour quels composants ?

🚀 L'assemblage du nouveau lanceur #Soyouz5 est terminé à Baïkonour. Il est équipé du moteur à ergols liquides le plus puissant du monde, le RD-171MV d'Energomach. Le lanceur porte aussi le nom kazakh Sunkar. Pas de date de lancement à ce jour (mars 2026 ?)

Well now ! @torybruno.bsky.social going to Blue on national security side, interesting !

🧵 My old collection of >100 high resolution images taken by Pleiades satellites between 2013 and 2021. My processing skills weren't very good and Bsky can't show full res, but here they are. I'm planning to add more from time to time. 1. Beijing-Daxing Airport terminal in China ( 2021-10-26 ).

potential EME alert 🚨- apparently the Japanese are signing up to bluesky in droves. If you check the newskies feed 99% of posts are now Japanese cc: @surfdude29.ispost.ing @laurenshof.online

Voici un atlas du Bluesky francophone. Avec plus de 300 000 comptes répertoriés, et 2000+ volontaires visibles. Tout visible, avec zoom et recherche, ici : ago-carto.fr/main.html?gr... PS: Il y aura une maj en janvier. Si vous n'êtes pas dedans, postez une réponse sur ce post pour être volontaire.

Reminder that the Spanish blackout was not due to frequency control/inertia but voltage control/réactive energy.

🇺🇸: It’s unacceptable to censor social media! 🇪🇺: It’s not censorship. X does not comply with transparency rules. Also 🇺🇸: Ban those books!!!!

I’ll just note that the US didn’t do this to China, which outright bans US social media websites

American social media platforms are banned in Russia. Have you noticed Donald isn't sanctioning anyone over that?

Do we bet that the political word will continue to use X like if nothing happened?

Will Europe react or continue to accept it?

Actual miss distance was closer to 5 km. In hindsight this should have been expected of a booster that didn't have enough engines firing on the way down.

Glutamate is the primary molecule that neurons use to communicate with each other. Previously, scientists have mostly recorded when neurons fire output signals, but now with a new glutamate indicator, they can record the many inputs that causes cells to fire. 🧵 #neuroskyence

As a solar astrophysicist, I spent a lot of time looking at solar flares this year. Out of them all, this X1.9-class #SolarFlare from December 1st was my favourite! The plasma motions are simply mesmerising.

This year there is loop flow on the grid. I have some very wrong calculation. It appears it is not possible to not take them into account. INVEST IN YOUR GRID !!!

There is a strong relationship between temperature & cumulative CO2 emissions. The relationship is different for CO2 concentration, but approximately linear: * CO2 concentration grows faster than cumulative emissions * Declining CO2 emissions leads to declining concentration rdcu.be/d9Rnm

Quand tous les réacteurs auront atteint leur pleine puissance et en supposant un facteur de charge de 90%, cela fera 8 GW débitant 63 TWh par an. Dans un pays qui produit encore 300 TWh/an au charbon, cela veut dire

Grosse désillusion ce matin avec le décollage d'une fusée japonaise H-3 qui s'est mal terminé (problème de performance + réallumage du 2è étage pour la mise en orbite GTO). Le satellite de positionnement QZS-5 est perdu. Mais surtout, le Japon a un problème de lanceur lourd.

I think it's a good idea to use cutting edge tech in prototypes. It helps to understand how it works and helps to evaluate the potential. But when the cutting edge turns to a bleeding edge, it's less fun.
