deep space
Far interstellar regions
Deep space refers to regions of outer space far beyond Earth's atmosphere and the moon—typically interplanetary, interstellar, or intergalactic distances.
NASA and other agencies use the term for missions venturing beyond Earth orbit: The probe transmitted data from deep space.
In science fiction, deep space evokes the vast, empty reaches between stars where anything might happen.
