Light Emitting Diode
Because it does emit light of its own rather it reflects light from other celestial bodies
The atom must be subjected to a form of energy which propels the electron(s) to a higher energy level. When the electrons return to their resting state they emit one photon of light at a certain wavelength that our eyes interpret as a color.
When electrons change energy levels, they emit light or energy in the form of electromagnetic radiation. This emitted light can have specific frequencies or colors, depending on the difference in energy levels that the electron undergoes.
Fireworks emit light through three processes: incandescence, luminescence, and incandescence. Incandescence is the glowing of heated particles, luminescence is the emission of light without heat, and chemiluminescence is the light emitted from a chemical reaction.
They emmit light because they have many stars.
Lithium salts do not emit green light because their electron transitions do not correspond to the energy levels associated with green light emission. Similarly, copper salts do not emit red light because the energy levels of their electron transitions do not produce red light emission. Each element's electron transitions are specific to its atomic structure, dictating which colors of light are emitted.
Silicon and germanium are indirect bandgap semiconductors, which means that they do not naturally emit light. In order for these materials to emit light, they need to be doped with specific impurities or be subjected to external stimuli such as electrical current or radiation to create a population inversion and stimulate light emission through processes like electroluminescence or photoluminescence.

Some isotopes emit an electron on decay, others emit a positron (anti-electron).
Light bulbs emit light.
Technetium doesn't emit light.
bulbs emit light
Atoms emit light energy for several reasons: Atoms emit visible light most often when an electron moves from an excited state to a less excited state. Atoms accelerating at high rates can emit bremsstrahlung, or breaking radiation. Finally, atomic nuclei in an excited state can decay to less excited states, emitting light energy. This energy usually not visible though, in the X or gamma ray spectrum.
The Earth does not emit light, it like the moon reflects light
Some light sources can emit multiple types of light, such as white light sources that emit a combination of different colors.
