Question

why we are able to see the sky from earth is blue and from galaxy it is black??​

Answer 1

Answer:

Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Answer 2

• The daytime sky is blue because light from the nearby Sun hits molecules in the Earth's atmosphere and scatters off in all directions.

• At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright source of light, like the Sun, to be scattered.
