Question : 31 [SSC CGL (Pre)2007]
An astronaut in outer space will observe sky as
a) black
b) red
c) blue
d) white
Answer »Answer: (a)
Space is black because there are no substances or objects to reflect back any colour (or all colours, which would make it white). That is also why the astronauts see the earth as we see it in photos, but the space around it is black.
The light from the sun is reflected back as the blues and greens and browns that we see, but the space around the earth is just that - empty space and therefore does not reflect back any colours, so it is black.
