The Earth in the Universe
This 3D view of the Earth illuminated by the Sun, surrounded by the constellation of Orion and the star Sirius, is the result of numerical simulations combining satellite images of the Earth and algorithms of positioning of the objects (Earth, Sun, stars) on the celestial vault. It simulates a view acquired on March 21, 2022 at a distance of 50 000 km (*). Although plunged in the darkness, the artificial lighting draws the contours of the American continent.
