nightside
Planet's unlit half
The nightside is the dark half of a celestial body—the hemisphere facing away from the sun at any given moment.
The term appears in astronomy and science fiction: The probe descended toward Mercury's nightside.
By extension, nightside can suggest the hidden, dark, or unconscious aspects of something: exploring the nightside of human nature.
