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 ✊

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.

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)
