When viewed from space, the Sun emits light across the entire visible spectrum, making it appear white. Its yellow appearance from Earth is due to atmospheric scattering, which removes blue light, making it seem warmer in color.
While they appear light and fluffy, clouds are made of tiny water droplets. A typical cumulus cloud, about a kilometer across, contains hundreds of tons of water, equivalent to several blue whales, despite floating effortlessly.
Due to the way Martian dust scatters light, the blue light penetrates the atmosphere more efficiently than other colors. This creates a striking blue hue around the setting sun, a stark contrast to Earth's familiar red sunsets.
