Todos iremos morrer porque somos governados pelas pessoas mais estúpidas que já pisaram na Terra
European Commission President Ursula von der Leyen said today that the fight against climate change was not against the fuels that cause it — only the pollution they emit.
Von der Leyen says EU is not fighting fossil fuels, only emissions
The comment could undermine European countries’ push at COP30 to move away from coal, oil and gas.

Apep is an awesome system, unlike any other we know about.
Two Wolf-Rayet systems orbited by a third supergiant. As all their winds collide, they form these beautiful structures that have now been observed with #JWST and ESO's VLT.

This is a real image of a real thing that exists in the universe! And because a bunch of humans decided to get together and build a space telescope, we get to see it! 🤯
Very excited to share the NASA/ESA/STScI press release of our team's work on Apep! It's a terrific writeup, complete with a brand new beautiful visualisation of the nebula geometry.

🧵 Awful awful massacre in Brazil
Gente, é o maior massacre no Brasil desde o Araguaia. Entendo quem quer puxar pra Canudos ou Contestado ou etc, mas não podemos livrar a ditadura de 64 só porque ela escondia melhor seus corpos.
Morreram 41 guerrilheiros comunistas e mais de 1200 camponeses no Araguaia.

A US startup plans to deliver ‘sunlight on demand’ after dark. Can it work – and would we want it to?
Satellites beaming sunlight down to Earth sound like science fiction – and they have astronomers very worried.
