Astronomers for Planet Earth (A4E) is an international grass-roots movement of astronomy students, educators, amateurs and scientists, working to address The Climate Crisis from an astronomical perspective.
As astronomers, we focus our gazes upwards, away from Earth, away from home. However, the closest habitable planet is more than 40,000,000,000,000 kilometers away. We can learn much from our discoveries of distant worlds, but as noted by 2019 Nobel Laureate Michel Mayor, we cannot travel to them. As astronomers, it is our responsibility to inform the public that Earth is our only chance.
We have a unique point-of-view. Stretching the minds and imaginations of the public daily, we trigger awe while nurturing an astronomical perspective. We can turn this perspective inwards, back to Earth, bringing into the public’s focus the uniqueness, wonder and fragility of our only home—and the critical need to protect it & its climate.
Help us to address climate change from an astronomical perspective.
