How to make dark side surface brighter

Hi,
I have a simple problem. I want to see surface of the Earth on the dark side, during the night time.
With default settings I get completely black screen. And I want to see some mountains and textures, dark but still visible.

I understand that the default scene has only 1 light source as Sun, that’s why I can’t see anything on the side without sun.
But I guess there should be some solution for such cases. Maybe I should add some additional atmosphere scattering? Could anyone please guide my in the right direction?

Kind regards,
Nikita
