Convection.
Infrared radiations. They do not require any medium. So they don't heat any medium. They don't even heat the air through which they pass.
Heat transfer through vacuum primarily occurs through radiation. Since vacuum is devoid of air or other medium, conduction and convection, which require a medium, are not possible. Radiation is the transfer of heat through electromagnetic waves and can occur even in a vacuum.
Radiation is the heat transfer method that does not require a medium. It can occur through empty space, such as from the sun to the Earth, without the need for a material medium.
The transfer of heat through open space without the use of any medium is called radiation. Radiant heat travels in electromagnetic waves and does not require a medium to carry it. Examples include the heat we feel from the sun or a fireplace.
Convection requires a medium, such as a gas or liquid, to transfer heat through the motion of the medium itself. In a vacuum, there is no medium to carry the heat, so convection cannot occur. Heat transfer in a vacuum primarily occurs through radiation.

Both conduction and convection require an intervening medium, but convection requires the medium to be able to move.

Heat transfer by means of radiation doesn't heat the medium. In fact, radiation doesn't even require a medium in order to work. Strictly speaking, convection doesn't heat the medium either. Convection transfers heat by moving the medium around. Of course, heat also spreads throughout the medium by conduction while the convection is going on.
The transfer of heat energy through empty space is called radiation.
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
Conduction is the transfer of heat through direct contact between objects or substances. Convection, on the other hand, involves the transfer of heat through the movement of fluids (liquids or gases). In conduction, heat is transferred through a stationary medium, while in convection, the medium itself moves to transfer heat.
Radiation is a type of heat transfer that does not require a medium to travel through. It can occur through space and air, as it involves the transfer of heat energy in the form of electromagnetic waves.
Heat transfer goes from an area of higher temperature to an area of lower temperature. This transfer can happen through conduction, convection, or radiation, depending on the medium through which heat is being transferred.
