All objects and living things emit infrared radiation unless the object is not a black hole as well unless its temperature is not at the Absolute Zero ( I would call it an "infrared black hole") - such an object can only absorb infrared radiation.
All warm bodies emit thermal radiation, which is a type of electromagnetic radiation that can be felt as heat. This radiation is a result of the movement of atoms and molecules within the body, and its intensity and wavelength depend on the temperature of the body.
All objects with a temperature above absolute zero emit infrared radiation. This includes humans, animals, plants, and inanimate objects like rocks and buildings. The amount of infrared radiation emitted depends on the temperature of the body.
Black bodies in physics and astronomy are theoretical objects that absorb all incoming radiation and emit radiation based on their temperature. They are used as idealized models for understanding the behavior of thermal radiation. The characteristics of black bodies include their ability to absorb and emit radiation at all wavelengths, as well as their emission spectrum being determined solely by their temperature. In astronomy, black bodies are used to approximate the radiation emitted by stars and other celestial bodies. The implications of black bodies in physics and astronomy include their role in understanding the thermal properties of objects in space, as well as their importance in developing theories of radiation and energy transfer.
Humans emit heat waves in the form of infrared radiation. This radiation is a type of electromagnetic wave that is given off by our bodies as heat energy.
Bodies that emit light produce their own light through a process like thermal radiation or chemical reactions, while bodies that reflect light simply bounce off light that falls on them from another source. Emitting light produces self-generated illumination, while reflecting light allows an object to be visible by reflecting light from external sources.

Some bodies in space that emit light include stars, galaxies, and active galactic nuclei. Stars emit light through nuclear fusion in their cores, while galaxies and active galactic nuclei emit light from the energy produced by supermassive black holes at their centers.
Bodies which emit light are luminous bodies and those who don't emit light are known as non luminous bodies Example - stars are luminous bodies while planets are non luminous bodies Tube light is a luminous body while a chair is non luminous
Massive celestial bodies of gases that emit heat and light by radiation are stars. They are primarily composed of hydrogen and helium gases, and the nuclear fusion reactions occurring in their cores generate the heat and light that they emit.
There is a chemical in their bodies called luciferin. They mix it with several other chemicals and enzymes to create a reaction that puts out the yellow-green light you see.
Hotter bodies emit wavelengths which peak at the shorter end of the spectrum.
All objects with a temperature above absolute zero emit infrared radiation. This includes humans, animals, plants, and inanimate objects like rocks and buildings. The amount of infrared radiation emitted depends on the temperature of the body.

Objects that emit light when heated are called incandescent bodies. This phenomenon occurs due to the thermal energy causing the atoms in the material to vibrate and emit photons, resulting in light emission. Examples include light bulbs and stars like the sun.
The solar system
Black holes are believed to emit something called Hawking radiation.
