Photon

In space and astronautical engineering, a photon is an elementary particle that represents the quantum of the electromagnetic field, including electromagnetic radiation such as light. Photons are massless and travel at the speed of light. They have both wave-like and particle-like properties, and can be described by their energy, frequency, and wavelength. Photons play a crucial role in many space-related technologies, including solar cells, telescopes, and communication systems. They are also important in the study of astrophysics, as they are emitted by stars and other celestial objects and can provide information about their properties and behavior.
