Yes, every object with a temperature above absolute zero emits radiation. This phenomenon is known as thermal radiation or blackbody radiation.
The amount and type of radiation emitted by an object depend on its temperature. According to Planck's law of blackbody radiation, as the temperature of an object increases, the intensity of radiation it emits also increases, and the wavelength distribution of the radiation shifts to shorter wavelengths.
For objects at everyday temperatures, such as room temperature, the emitted radiation is in the infrared range, which is not visible to the human eye. However, at higher temperatures, objects start to emit visible light, and at even higher temperatures, they emit ultraviolet, X-ray, and gamma-ray radiation.
It's worth noting that the specific wavelength distribution and intensity of radiation emitted by an object depend on its temperature and material properties. Different materials have different emissivities, which describe how efficiently they emit and absorb radiation at different wavelengths.
