Enjoy our living Earth, with the Moon and the Sun drifting against the backdrop of the Milky Way. A truly relaxing way to slow down and find calm in a stressful moment. A strikingly realistic Earth : - Terrain relief, clouds with relief, shadows and altitude - Night side glowing with city lights, softly diffused through the clouds - Storm cells animating in the clouds on the night side - Sun reflections on the oceans, eclipses and sun masking - Atmospheric scattering around the globe - A detailed Moon with relief, eclipses, and its shadow cast on Earth - All of it set against the Milky Way and the real night sky - A perfect way to reconnect with the quiet beauty of our world. Tailored to your device: the level of detail and visual effects automatically scale to your device — the more powerful it is, the richer and sharper the experience. Controls : - Drag with one finger to rotate around the Earth; pinch with two fingers to zoom. - Switch camera modes with the top-right buttons: free, orbital, or geostationary. - Pause the animation with the top-left button — then breathe in, and breathe out. - Hold the bottom-right button to speed up time.
