Why Does The Sky Get Dark At Night. Extending the analogy to three dimensions, if the universe of stars is large enough, your. Imagine you are deep in a forest.
Since the earth rotates on its axis for more or less half the period of rotation any given location on earth is facing away from the sun, except in the case of extreme latitudes. The reason the night sky is dark is our distance from the nearest stars (over 4 light years) which would be as bright as our sun (93 million miles) if they were not over 2500 times further away and only the brightness of a star, not the sun. These are in the shadows of planets, moons and other objects in orbit around the sun.
So The Bright Nights, At The Most Basic Level, Are The Result Of Snow Flakes Keeping The Reflected Light In The Atmosphere.
Why the night sky is dark? By 'dark sky' astronomers really mean 'free of artificial light pollution'. But you might start to wonder a little more deeply than that.

Why is the night sky dark blue instead of black in childrens animated movies. Streetlights many miles away) then the site is not truly dark. In fact the closest star, apart from our sun is so far away that its light is at least 500 billion times less bright than our sun, and that is.
Ultimately, The Nature Of The Universe Itself — Expanding, Evolving, And With A Finite Age — Are The Reasons That We Do Not See Light All.
But if you stand in a large forest, your view is everywhere blocked by a “solid wall” of tree trunks. Extending the analogy to three dimensions, if the universe of stars is large enough, your. Why does the sky get dark at night?

The night sky definitely has colours, but they are too faint to see just with the eye. If the universe is static and populated by an infinite number of stars, any sight line from earth must end at the (very bright) surface of a star, so the night sky should be completely bright. Anything farther, and the light just wouldn't have had enough time to get there yet.
