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.



A new study uses Earth as a stand-in for an exoplanet and shows that even with very little light -- as little as one pixel -- it is still possible to measure key characteristics of distant worlds.
