with radiators that release electromagnetic radiation into space.

Explanation:

Spacecraft use radiators that release electromagnetic radiation into space to get rid of excess heat.

Since outer space is a near perfect vacuum, this means that many of the common ways that heat is expelled on Earth do not work in space. Since spacecraft do not touch any other objects in space, they cannot lose heat through conduction. Since there is no air, they cannot lose heat through convection either. Instead, spacecraft use specially designed radiators, which emit excess heat as electromagnetic radiation-infrared light.
