What is the Overview Effect ?

The Overview Effect is the profound shift in perspective that astronauts experience when they see the Earth from space. From orbit or the Moon, they describe an overwhelming awareness of our planet as fragile, alive, and without borders — a single shared home. First identified in 1987 by space philosopher Frank White, this experience has been called nothing less than life-changing.

For the first time in history, OneHome makes it possible for everyone to access this transformative vision without leaving the ground. Using authentic NASA images taken by the DSCOVR satellite — located 1.5 million kilometers away at the unique vantage point of Lagrange Point L1 — OneHome offers real videos of the Earth fully illuminated. Enhanced with the creativity of artists and inspirational voices, these images convey the same sense of awe and belonging felt by astronauts.

The Overview Effect is more than a vision: it awakens awe, unity, and responsibility. OneHome’s mission is to spread this awareness across the world, turning emotion into action. Through the Blue Revolution Map, communities everywhere are invited to organize events, share this perspective, and help build a global movement of care and love for our planet.
