how dark is it in interstellar space?

At the half way point Alpha Centauri would be a little brighter, but not much brighter, and the Sun would look like a bright star, but not the brightest one in the sky. In other words, it would look just like night time on Earth when the sky is very clear and very dark, for example from a remote mountain top.

If you could find a gas that had a semi-stable quasistate that when excited would release a photon with a wavelength corresponding to "black", then yes.  However, I don't know exactly what band that would be.  The closest you'd be able to get to black would be a dark ultraviolet, or if you could overlap in phase multiple color lasers which could possibly (but unlikely) add together to make the appearance of black.  Most likely, you're out of luck.

If you made a scale model with the distance from the earth to the sun scaled to be one inch, the distance to the *nearest* star other than the sun would be over 4 miles! Most of the stars we see at night (without a telescope) would be from 4 miles to over 1000 miles on this scale.\n\nSo the basic problem with interstellar travel is that the distances are absolutely incredible. The farthest that a probe of ours has travelled is about 9 feel on this scale and it has taken 3 decades to do that.

According to Astronomers Karl Glazebrook and Ivan Baldry at Johns Hopkins University :\n>>All the light in the universe from as far back as several billion years ago averaged out to a shade of turquoise, somewhere between pale turquoise and medium aquamarine. Such color however was revised shortly due to their claim that the software program  used was calibrated incorrectly. They said that the average colour of the universe is actually "cosmic latte" (beige colour).♥

It is definitely the sun. Alpha Centauri is nearly 4 light years distant. The sun is nearly 8 light minutes distant.

Dust and the expanding universe keep the night sky dark.

it depends on your place in space. are you in a straight line with a planet and sun,  then there is night and vice versa

The Big Bang theory offers a resolution of your question (also known as Olbers's Paradox). In a universe with a beginning we can receive light only from that part of the universe close enough so that light has had time to travel from there to here since the Big Bang (about 10 billion years ago). So, even if space extends infinitely far, only a limited region, and a limited number of stars, are visible to us. And the accumulated light from this limited number of stars is not sufficient to spoil the darkness of the night sky.\n\nGod is spelled B-I-G B-A-N-G\nPBrax@netscape.com

Sunlight from the Sun would have to reflect off something in space in order for that region of space not to appear black.  For example the Moon doesn't look black because Sunlight is reflecting off its surface.\n\nSpace is for the most part black since there is an absence of material that can produce or relfect light there.

In a dark(ened) room.\nUse a smal lamp. Move it up and down. Choose one pupil and let the other ones see how the length of his shadow changes with the altitude of the lamp.

What you see outside at night is a mixture of these:\nStars (like the sun)\nPlanets\nSattelites\nGalaxies

This can be proven with a simple experiment.  Light travels at 186,000 mps, if you go to a desk or anything with a drawer that can be pulled out, while the drawer is closed it can be fairly safe to say that it's dark in the drawer.  When you open the drawer you will find that the dark excaped before the light got in.  So, you can safely say that darkness travels faster than the speed of light.

This is the same as the speed of light.  Dark is simply the relative absence of light.  The sun could stop shining and we would not know for like eight minutes.  (Not that the sun would just stop shining, but use your imagination.)

its done by counting how long it takes for light from the planet takes reach here. usually between a period of dark and light. same as the sun

You can tell whether a point of light in the dark sky is a satellite or star usually by whether it moves or not. Stars are very far away so they look stationary. Satellites usually moves across the sky. Whether or not the the satellites are Japanese, American, or Russian, you have to look up the satellite in astronomy programs that plot satellite trajectories. You can't tell just by looking.\n\nAlso, some bright lights can be just airplanes flying at high altitude.

The galaxy center is mostly obscured by dust.  Therefore, its brightness is greatly dimmed.

to make it visible in the dark sky at night( white is the most contrasting colour to black syk)
