Heat transfer through radiation is probably best illustrated by the warming of the earth by the sun. Electromagnetic energy from the sun in the form of light travels through the vacuum of space to reach the earth and warm us.
Some examples of energy transfer by radiation are:
1) standing in sunlight and feeling the heat on your face (UV radiation is entering the skin, converting to infrared radiation, and is absorbed by your tissues);
2) sitting near a fire and feeling the heat on your skin (infrared radiation transfer);
3) chemical reactions that occur due to a source of radioactivity (gamma radiation, being high-energy photons, travel from the radioactive source through the air into the target sample, and induce chemical reactions
Heat transfer by radiation is the only way heat can move through the relative emptiness of space. An example of this is when a person places their cold hands over a warm fire.

transfer of heat through open space is radiation
Yes. Radiation waves given off by the sun, heat the Earth through convection. Convection is the movement of heat transfer through liquids or gases, as seen in this example.

No heat transfer through objects touching is called conduction. Transfer by radiation occurs when heat moves in the form of electromagnetic waves such as light or infrared rays. The warmth you feel from sunlight is an example of radiation.
Transfer of heat energy through energy waves is called radiation.
Heat can be transferred in 3 ways: Conduction, or through direct contact, Convection, or transfer of heat through a fluid, or Radiation, or heat transfer through space in the form of electromagnetic waves.

There are three methods by which substances absorb heat. These are conduction, or heat transfer through contact, convection, or heat transfer through fluid motion, and radiation, or heat transfer through electromagnetic radiation.

Through radiation. Such as we receive heat from the sun through radiation when it's vacuum in space.
