You think probable to convection or radiation.
The movement of heat without matter to carry it is called radiation. Radiation is the transfer of heat energy in the form of electromagnetic waves, such as infrared radiation from the sun to Earth.
because it is always at space

Conduction.
CONVECTION
By FRICTION.
Conduction is the process by which heat is transferred between particles of matter without any movement of the matter itself. This occurs when particles vibrate and transfer their kinetic energy to neighboring particles. It is most efficient in solids due to their closely packed arrangement of particles.
heat.
Yes, conduction involves the transfer of heat through direct contact between particles in a material. The kinetic energy is transferred from the faster-moving particles to the slower-moving particles without the actual movement of matter.
convection
Heat transfer through a vacuum is called thermal radiation, where heat is transferred in the form of electromagnetic waves (like infrared radiation) without the need for a medium to carry it.
Convection is the method of heat transfer that involves the movement of both heat and matter. In convection, heat is transferred through the movement of fluids or gases. The hot fluid or gas rises, carrying heat away from the source, while the cooler fluid or gas sinks to replace it.
