This artist’s impression shows the view just above the surface of one of the middle planets in the TRAPPIST-1 system, with the glare of the host star illuminating the rocky surface. At least seven planets orbit this ultracool dwarf star 40 light-years from Earth and they are all roughly the same size as the Earth. They are at the right distances from their star for liquid water to exist on the surfaces of several of them. This artist’s impression is based on the known physical parameters for the planets and stars seen, and uses a vast database of objects in the Universe. Credit: ESO/N. Bartmann

These images show the sunlit side of Earth in 10 different wavelengths of light that fall within the infrared, visible and ultraviolet ranges; the images are representational-color, because not all of these wavelengths are visible to the human eye. Each wavelength highlights different features of the planet -- for example, the continent of Africa is visible in the lower right image, but is nearly invisible in the upper left image. These observations were obtained by NASA's Earth Polychromatic Imaging Camera (EPIC) instrument onboard the National Oceanic and Atmospheric Administration's Deep Space Climate Observatory, or DSCOVR, satellite, on Aug. 2, 2017.
