Radio waves travel through empty space because they are electromagnetic waves, whereas sound is a wave that must travel through air.
No, mechanical or pressure waves can not travel through empty space
Sound waves cannot travel through an empty space because an empty space is usually a vacuum.

radio astronomy
The communication was done using radio signals which can be transmitted in a vacuum. Radio waves are part of the electromagnetic spectrum, as are light waves, x-rays and microwaves. Just as light from far distance stars travel through empty space and reach your eyes, so can radio waves travel through space to a radio receiver.
Light, a combination of oscillating electric and magnetic fields.
Light waves do, but sound waves cannot, because in space is no medium to carry the vibration. Radio, TV and others can travel in space also.
