The Pale Blue Dot is an iconic photograph of Earth captured by the Voyager 1 space probe in 1990. Taken from a distance of around 6 billion kilometers (3.7 billion miles) as Voyager 1 was departing our solar system, the image portrays Earth as a tiny, pale blue speck in the vastness of space. This image is a powerful reminder of our planet's isolation and fragility in the cosmic expanse, highlighting the need for responsible stewardship of our home. The photograph was a result of astronomer Carl Sagan's suggestion to turn Voyager's camera back towards Earth, offering a profound perspective on our place in the universe.

I'm really proud to announce that I've launched a new organization, Global Shield, with my co-founders @ArielConn and Jared Brown. We advocate for government policy on global catastrophic risk. The risk is only growing, so Global Shield is about getting government to act.

Hello X-verse! We are happy to announce Global Shield as the world’s first international advocacy organization devoted to reducing all-hazards global catastrophic risk (GCR). Give us a follow and learn more about us at our website. globalshieldpolicy.org/
