Question

The sky is dark in the moon . Why? pls explain

Answer 1

The moon is tidally locked with the earth, meaning that the same side always faces earth. Since the moon also orbits around the earth (with a period of a lunar month), this means each side changes, over the course of a lunar month, between facing towards the sun and facing away. This is the cause of the phases of the moon, and also describes the day/night cycle for the moon: a full moon is when the side that we can see faces the sun - i.e. "day" for that side - and a new moon is when the side that we can see faces away from the sun - "night". So the moon does have night and day, but a night/day cycle is one lunar month long.

However, this doesn't answer your question of why the sky is always dark when viewed from the moon - even when the sun is above the horizon.

Answer 2

in simple way we explain that there is no atmosphere at moon so no gaseous particles are there and we know that without any me Daimler light can't reflect for it there should be medium of solid.,liquid or gas to see something using light and eyes but at moon between space have no medium so light can't scatter in all cases when it is not then the further seems as black. by an iitian way
