A photon is an elementary particle, the quantum of light and all other forms of electromagnetic radiation. It is the force carrier for the electromagnetic force, even when static via virtual photons.he energy of a system that emits a photon is decreased by the energy of the photon as measured in the rest frame of the emitting system, which may result in a reduction in mass in the amount. Similarly, the mass of a system that absorbs a photon is increased by a corresponding amount.
THE SOLAR SYSTEM WIKI. Pluto. 134340 Pluto, more commonly known simply as Pluto, is the second-largest known dwarf planet in the Solar System, and the tenth largest observed body directly orbiting the Sun. It orbits between 29 and 49 AU from the Sun, and was the first Kuiper Belt object (KBO) to be discovered.
In 1983, CERN announced the discovery of the W and Z particles.The image above shows the the first detection of a Z0 particle, as seen by the UA1 experiment on 30 April 1983.
