Heat by radiation will most likely be transferred through empty space by thermal radiation.

Explanation:

Radiation is method in which heat is transferred without depending upon the contact of heat source and the heated object, which happens in the case of conduction and convection. The heat can be transferred through the empty space by the help of thermal radiation. This complete phenomenon is called as the infrared radiation. Which is a type of electromagnetic radiation. The heat is found to be convected in the atmosphere when the warm particles are transferred from one location to another.
