Although conceptually and empirically the rounded form of the Earth's was no longer in doubt, aerial photography fundamentally transformed the representations of the world. The vertical shots produced for the first time allowed the Earth to be seen in its entirety and helped to forge a new global environmental consciousness. What Denis Cosgrove called ""new global spatialities"" also represents new modalities of subjectification. With this in mind and to celebrate the Earth Day in 2014, NASA broadcasted an image of the globe made up of tens of thousands of selfies sent by Internet users. By combining the two paradigmatic practices that delimit the field of geographical exploration (representation of the terrestrial globe and selfie), NASA perfectly illustrates the idea of ??a universal Earth, everywhere habitable and inhabited. On the basis of these elements, this article revisits both the historical links between photography and geography and what I would call vernacular geographical knowledge: the practice of taking selfies. It will then be necessary to show how the image produced by NASA is part of the new ideal of subjectification which makes the Earth object a kind of sovereign everyone is called upon to identify with.
