Yes, all objects above absolute zero temperature radiate energy in the form of electromagnetic radiation. This phenomenon is described by Planck's law of blackbody radiation, which states that the intensity and wavelength distribution of the radiation emitted depend on the temperature of the object. Even objects at room temperature emit infrared radiation, although this emission is not visible to the human eye.
Yes, it still has some amount of internal energy or "heat". Even considering the coldest objects in the universe, it is still impossible for an object to have no heat, and this theoretical state is known as absolute zero.
Heat doesn't travel through a vacuum. The energy could be changed to light and radiate across the gap, so that would be radiation.
Electromagnetic radiation.
Her face seemed to radiate kindness. Spokes radiate from an axle.
There are three mechanisms by which thermal energy (heat) is transferred through space: conduction, convection, and radiation.1Radiation is the transfer of heat energy through empty space. All objects with a temperature above absolute zero radiate energy at a rate equal to their emissivity multiplied by the rate at which energy would radiate from them if they were a black body. No medium is necessary for radiation to occur; radiation works even in and through a perfect vacuum. The energy from the Sun travels through the vacuum of space before warming the earth. Also, the only way that energy can leave earth is by being radiated to space.The transfer of thermal energy through space is called Radiation
Objects that can radiate energy include stars, light bulbs, heated coils, and the Earth's surface. The type of radiation (such as heat, light, or electromagnetic waves) emitted by an object depends on its temperature and composition.

Yes, all objects in the universe radiate some form of energy in the form of heat. This radiation is known as thermal radiation and occurs due to an object's temperature causing its atoms and molecules to emit electromagnetic radiation.

Yes, hotter objects radiate more total energy per unit area than colder objects. This is described by Stefan-Boltzmann's law, which states that the total energy emitted by a blackbody is proportional to the fourth power of its temperature.
Yes, all objects radiate some heat BUT the hotter the object, the more heat it radiates!! radiation its self is not hot but when it is absorbed by an object its particles in the object move more rapidly thus heating it
All bodies are subject to entropy, the constantly increasing disorder of the universe, all energy tends to thermal equilbirum thus, places of high energy/temperature/ pressure/ will radiate into places of lower energy/ temperature/ pressure. Also see wiki on blackbody radiation for more detail on that topic.
The Earth re-radiates electromagnetic energy due to its temperature. Like all objects, the Earth emits thermal radiation in the form of infrared energy as a result of its heat. This process helps maintain the Earth's energy balance.

Hot objects radiate more heat than cooler objects because they have higher internal energy due to their higher temperature. This causes them to emit more thermal radiation in the form of heat. The rate of heat radiation increases as the temperature of the object increases, according to the Stefan-Boltzmann law.
It is because stars and other cosmic objects, radiate energy across the whole of the electromagnetic spectrum.
