Is there heat transfer in vacuum?

Heat transfer in vacuum takes place by the means of heat transfer process called RADIATION. Radiation does not require the presence of a material medium to take place. read more

There are three ways that heat can transfer, from a hotter body to a colder one—conduction via direct contact; convection via the flow of fluids; and radiation via the propagation of electromagnetic waves. An object with temperature higher than the absolute zero emits radiation that can travel in vacuum. read more
