Why do astronauts see space black? As there is no atmosphere in space and hence light does not scatter into its constituent colors that is why the sky appears dark instead of blue to an astronaut in space. This phenomenon is an example of a scattering of light.
Hereof, What is the black stuff in space?
What is dark matter? Dark matter is stuff in space that has gravity, but it is unlike anything scientists have ever seen before. Together, dark matter and dark energy make up 95% of the universe.
Hereof, What is the true color of space? If we add up all the light coming from galaxies (and the stars within them), and from all the clouds of gas and dust in the Universe, we'd end up with a colour very close to white, but actually a little bit 'beige'.
what's more, Is the universe dark?
It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the universe.
Why is the sun so hot but it's cold in space?
The reason is obvious: sunlight contains energy, and in near-Earth space, there is no atmosphere to filter that energy, so it's even more intense than it is down here. Now, on Earth, if you put something out in the sun, it warms up.

Are there colors we Cannot see?
Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously. The limitation results from the way we perceive color in the first place.
Do colors exist in space?
But, did you know that colors exist that you cannot see? Color does not change in space, because the wavelengths remain the same. Although you can see all the colors of the rainbow, plus every color mixture from those colors, you only have three color detectors in your eyes.

What is darkness made of?
Most scientists think that dark matter is composed of non-baryonic matter. The lead candidate, WIMPS (weakly interacting massive particles), have ten to a hundred times the mass of a proton, but their weak interactions with "normal" matter make them difficult to detect.
Are human a matter?
yes huamns are also considered as matter because it has a mass and also a weight .
Why there is no life on the moon?
The Moon's weak atmosphere and its lack of liquid water cannot support life as we know it.
Why is it always dark on the moon?
The moon doesn't have an atmosphere, so there are no twilight colors. From the moon, the sky always looks black, even during the lunar day when the sun is shining in the moon's sky. Here on Earth, our planet's spin on its axis carries us from daylight to darkness and back again every 24 hours.
Would you actually freeze in space?
Acute exposure to the vacuum of space: No, you won't freeze (or explode) The absence of normal atmospheric pressure (the air pressure found at Earth's surface) is probably of greater concern than temperature to an individual exposed to the vacuum of space .
What is the hardest color for humans to see?
Blue is the hardest color to see as more light energy is required for a full response from blue-violet cones, compared to green or red.
Why is magenta not real?
Magenta doesn't exist because it has no wavelength; there's no place for it on the spectrum. The only reason we see it is because our brain doesn't like having green (magenta's complement) between purple and red, so it substitutes a new thing.
Are pictures from space colored?
That's easy. It's in black and white. You might not know this, but almost every photo of space starts out this way. Additionally, most telescopes only take black-and-white pictures, the most prominent of which probably being the Hubble Telescope.
Are nebulae actually colorful?
Emission nebulae tend to be red in color because of the abundance of hydrogen. Additional colors, such as blue and green, can be produced by the atoms of other elements, but hydrogen is almost always the most abundant. They usually tend to be blue in color because of the way that the light is scattered.
