Is there no noise in space?

Unlike light, sound requires a medium to travel through. This simply means that in order to hear sound there has to be something for sound to travel through. In the vacuum of space, there are no (or very, very few) particles to vibrate, so sound cannot travel through this medium.

Is there smell in space?

Astronaut Thomas Jones said it “carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous.” Tony Antonelli, another space-walker, said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I …

Why there is no light in space?

In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.

Why Sun is not visible at night?

From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles.

Why we can see moon at night?

Why can you always see the moon but not the sun?

The answer is somewhat simple: The moon and stars are always somewhere in the sky, but we can’t always see them. As the moon continues in its orbit around the Earth, away from the sun, increasingly more of its sunlit surface is visible. This is why the moon sometimes appears as a crescent or half-moon.
