text:  At night, when we're farther away from the sun, you have an absence of sunlight. And without the sun's light illuminating the atmosphere, the sky just looks dark. It's kind of like, you know, if you're in a room and you turn the lights out, the room looks dark. It's not that the room didn't change color. It's just darker because there's less light. That's what you're basically seeing at night.
