A view of the picture depicting Earth by night as taken from a satellite proves that night times on Earth are not as dark as all of us believe. The fact is that Earth is never completely dark when as the glow from manmade structures and nature light our planet. The light shines even when no human settlements are around as volcanoes rage and wildfires burn. Gas and oil wells flicker like matchsticks. Auroras adorn the skies of the polar region. Starlight and moonlight reflect from the water, clouds, deserts, and snow. Sometimes, even the ocean and air appear to be glowing.
