Radiant energy is exothermic energy. Fire is a chemical reaction that produces heat. This heat is released as a result of the exothermic chemical reaction.
Radiant energy is defined as the energy of electromagnetic radiation. This means that radiant energy is caused by the oscillation of electric and magnetic fields.

Radiant energy is the energy of electromagnetic waves. The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time and, like all forms of energy, its SI unit is the joule. The term is used particularly when radiation is emitted by a source into the surrounding environment. Radiant energy may be visible or invisible to the human eye. The term "radiant energy" is most commonly used in the fields of radiometry, solar energy, heating and lighting, but is also sometimes used in other fields (such as telecommunications). In modern applications involving transmission of power from one location to another, "radiant energy" is sometimes used to refer to the electromagnetic waves themselves, rather than their energy (a property of the waves). In the past, the term "electro-radiant energy" has also been used. Historically, the propagation of electromagnetic radiation was presumed to rely on a medium filling all space, known as the aether. Electromagnetic waves were presumed to propagate through this medium by inducing transverse electric and magnetic stresses and strains, analogous to those induced by shear waves propagating through a physical medium. In modern times, the propagation of electromagnetic waves has been shown not to require any physical medium, although some interpretations of general relativity can be viewed as implying that space acts as a kind of non-physical "medium" for light.
A small frozen mass of dust and gas revolving around the sun. It lights up.
The pupil does not absorb anything, it transmits light energy to the retina at the back of they eye, the retina does the absorbing. It certainly does not emit anything either, though aliens in scifi films can have glowing eyes! Some animals like cats have reflective eyes, but they are not emitting light, only reflecting incident light.
A fireplace emits radiant energy through the process of combustion. When wood or fuel is burned in the fireplace, it releases heat energy in the form of infrared radiation. This radiant energy then warms objects and people in the vicinity of the fireplace.

Radiant and thermal
The heat energy you feel from a fireplace is primarily radiant heat. This heat is given off by the fire and warms objects and people in close proximity. The amount of heat felt will depend on the distance from the fireplace and the size of the fire.
Radiant energy is similar to light energy in that it consists of electromagnetic waves that can travel through space. Just like light energy, radiant energy can carry heat, can be absorbed or reflected by objects, and can be converted into other forms of energy, such as electrical energy.
Non-examples of radiant energy include sound waves, thermal energy transferred through conduction, and mechanical energy generated by moving objects. Only electromagnetic waves, such as light and infrared radiation, are considered forms of radiant energy.
Radiant energy is a form of energy that includes visible light, ultraviolet light, and other electromagnetic waves. It can heat objects, power solar panels, and is crucial for photosynthesis in plants.
Radiant energy, such as light and electromagnetic waves, is not directly associated with the particles of objects and can travel through a vacuum.
Infrared radiation is the form of radiant energy on the electromagnetic spectrum that is emitted by objects as they lose thermal energy to their surroundings. This type of radiation is not visible to the human eye but can be felt as heat.
Radiant energy, like light and heat, travels in waves and can be absorbed by various materials. It can be emitted by objects due to their high temperature or by electronic processes. Additionally, radiant energy can be harnessed and converted into other forms of energy, such as electricity.
