Why are socialists all over the world so focused on an election in New York?

For the same reason the US spent the 20th century toppling democratically elected socialist leaders.

Because ours is an internationalist movement - a victory for one is a victory for all ✊

Comunidade brasileira de Astronomia e Astrofísica, @sabastronomia.bsky.social , têm considerado publicar nessa revista ja que #ApJ, #A&A e #MNRAS com seu "open access" dificultam que publiquemos nelas?

Wow

This intriguing NIRCam (Near-Infrared Camera) image from #JWST shows, in incredible detail, a view of remnant supernova Cassiopeia A (Cas A), including the expanding shell of material flapping into the gas shed by the star before its explosion.

🌍 Happy #Equinox! On 20 March 2025 at 09:01 GMT/10:01 CET, just a few moments ago, the Sun appeared directly above Earth's equator - with our planet neither tilting towards nor away from the Sun!

Mare Nectaris is the result of a large impact on the Moon early in its history, around 3850 million years ago. You can see the border of the crater as an irregularly shaped wall. I took this image yesterday from my backyard. This is the Moon's waning gibbous phase. 🧪 🔭

physics of climate impacts 101:
- Stuff gets hot (worse heatwaves)
- Hot air holds more water vapor (heavier rainfall)
- Hot air is thirstier air (higher drought risk)
- Warm water is hurricane food (stronger storms)
- Hot water expands and hot ice melts (sea level rise)

Muito bem apontado, parafraseando livremente: se acreditamos na ciência das mudanças climáticas, mas nos comportamos como se o mundo de amanhã vai ser o mesmo de hoje, nós somos os negacionistas!

@elianebrum.sumauma.com tirando um nó da minha garganta, falando tudo o que esta me sufocando faz tempo.
Negacionismo es ser consciente de lo que ocurre, pero negarlo para seguir con la vida, como si la amenaza fuera a desaparecer milagrosamente. Este negacionismo nos está matando.
