Is the night sky actually black or is it really just dark blue?

Answer 1

Sometimes it's red.

Answer 2

Dark Blue

Answer 3

there is no longer sufficient gentle to gentle up it. Black is definitely no longer a colour, that is a lack of light. For the sky to be lit, there might want to be a mild source. In daylight hours, it really is the daylight. Rayleigh scattering of sunlight makes the sky blue, as considered from the floor. At nighttime there is not any sunlight to attempt this, and the small volume of light from the planets and stars isn't sufficient to colour the sky. sometime, notwithstanding, a brightly lit moon may have a halo, by using atmospheric situations. This seems as a hazy ring around the moon.

Answer 4

Without an atmosphere (like on the moon) it would be black (except of course where the stars are). On earth, some of the starlight (and moonlight, if the moon is up) is scattered by the atmosphere, so the sky isn't really black.

A very deep blue is probably the best description of the color, although color is a perception and the human eye isn't sensitive enough at that low level of light to detect color. The cones in our eyes detect color but require quite a bit of light to be activated. The rods in our eyes are sensitive to even low levels of light, but do not distinguish color. (That's why objects in a dark room don't appear colored.)

Answer 5

Space itself is black, but the night sky we observe from Earth is accually a dark blue. The sun's light reflects off of the moon and the light from the moon shines on Earth and the light scatters in the atmospear causing a dark blue color. It's the same even in a new moon also.

Answer 6

The person that said the sky is black and devid of color is so wrong. The night sky, for reference sake, is what our atmoshpere looks like without sunlight on it. However, multiple analysis by NASA and a whole variety of astronomersm when using a digital and/or nuclear powered spectroscope/spectragraph, have determined it to be a dppe green. The human eye doesn't see this for many reasons - air pollution, city ights, etc, but you can find all sort of info on this if you put it in your search engine, maybe even NASA or the Jet Propulsion Laboratory sites.

Answer 7

It's actually black. There is no sunlight refracting through the atmosphere (which is what gives the sky it's blue color during the day and the really gorgeous colors at sunset), so you're staring off into deep space.

Answer 8

The space between stars has no color, there for it appears black. Remember that color is just the eye perceving the light that is reflected off of particles.

So taking that in mind, perhaps we are observing the Dark Matter that everyone keeps talking about?

Answer 9

When we look up at the stars at night we are seeing through a transparent earth atmosphere. Yes the black background seen behind the stars acutally how it looks from everywhere in space.

Answer 10

The night sky is black!!! Ask a science teacher though
Remember the abscence of color is black

Answer 11

there's no light during night time.. the absence of light is darkness.. so it's actually black.. the dark blue results from the light pollution from most industrialized areas..
