Say I am in a space shuttle and have reached outer space. Is it true that during the day it possible to see stars outside through the window? Do I have to wait until night? Why is this the case?
There is no day and night in space!
Day and night on earth are defined as times when the earth is whether we are facing towards the sun or opposite to the sun. When we are facing the sun, the light from the sun scatters due to the atmosphere and makes the sky appear blue.
On moon there is very little atmosphere, so even during the day, the sky appears black. So theoretically, if you can sustain the heat and the blinding radiation from the sun, you should be able to see stars when you are facing the sun on the moon. Similarly in a space shuttle.
P.S. I surprisingly couldn't find any links on google regarding how daytime would look on the moon. has no one ever wondered about this?
