every time i see a white guy in their fifties radicalized by the twitter algorithm into racism and extremism i think about how it's a total failure of the youtube algorithm to instead radicalize him into home brewing, elaborate A/V setups, or DIY solar

I made this Pride flag using only NASA images and our team thought it would be cool to share on social (I work on the NASA heliophysics communications team), but it's getting all sorts of hate on the bird app and Fbook. Thought y'all might be more appreciative of it here. ☺️🏳️‍🌈💖

A pride flag with every color band represented by a NASA image. White is Earth clouds, pink is aurora, blue is the Sun in a specific wavelength, brown is Jupiter clouds, black is the Hubble deep field, red is the top of sprites, orange is a Mars crater, yellow is the surface of Io, green is a lake with algae, blue is Neptune, and purple is the Crab Nebula in a specific wavelength.

The President of the United States is threatening to commit war crimes and wipe out a "whole civilization" — all because he started a disastrous war of his own making and had no plan and no strategy for how to end it. This is abhorrent, and the American people do not support this.

It is very easy to become accustomed to Trump’s ravings, and laugh them off. That’s a dangerous thing to do. When Trump states: “A whole civilization will die tonight,” he is threatening to commit genocide. We can’t allow that to happen. Congress must end this war NOW.
