The thermal transfer of energy by electromagnetic waves through the vacuum of space is called
Olenka [21]

Answer: Radiation

Explanation:

There are three ways in which the thermal transfer occurs:

   1. By Conduction, when the transmission is by the <u>direct contact</u>.

  2. By Convection, heat transfer <u>in fluids </u>(like water or the air, for example).  

   3. By Radiation, by the <u>electromagnetic waves</u> (they can travel through any medium and in <u>vacumm</u>)

So, in the outter space is vacuum, this means the energy cannot be transmitted by convection, nor conduction. It must be transmitted by electromagnetic waves that are able to travel with or without a medium, and this is called radiation.
