"Glow in the dark" and its derivative terms have been used to refer to various groups: newcomers that do not fit in with the culture of certain forums and are thus suspected to have bad intentions, journalists who report on extremist groups, tech companies that collect users' personal data, and others.

Foxfire in the fungus Panellus stipticus Blue ocean glow caused by myriad tiny organisms, such as Noctiluca. Noctiluca scintillans, a bioluminescent dinoflagellate. Bioluminescence is the production of light by living organisms. This list of bioluminescent organisms is organized by the environment, covering terrestrial, marine, and microorganisms.
Solar ray 1 is the lowest from the Sun – the Sun is set. Solar ray 2 is reflected in the (snow) clouds to the observer. Alpenglow (from German: Alpenglühen, lit. 'Alps glow'; Italian: enrosadira) is an optical phenomenon that appears as a horizontal reddish glow near the horizon opposite to the Sun when the solar disk is just below the horizon.
The glowing esca is dangled or waved about to lure small animals to within striking distance of the fish. [ 34 ] [ 65 ] The cookiecutter shark uses bioluminescence to camouflage its underside by counter-illumination, but a small patch near its pectoral fins remains dark, appearing as a small fish to large predatory fish like tuna and mackerel ...
E.g. is often confused with i.e. (id est, meaning ' that is ' or ' in other words '). [12] Some writing styles give such abbreviations without punctuation, as ie and eg.

In rhetoric, a glittering generality or glowing generality is an emotionally appealing phrase so closely associated with highly-valued concepts and beliefs that it carries conviction without supporting information or reason. Such highly valued concepts attract general approval and acclaim.
Radioluminescent paint is a self-luminous paint that consists of a small amount of a radioactive isotope (radionuclide) mixed with a radioluminescent phosphor chemical. The radioisotope continually decays, emitting radiation particles which strike molecules of the phosphor, exciting them to emit visible light.
Common examples include fluorescent lamps, organic dyes, and even fluorspar. Longer emitters, commonly referred to as glow-in-the-dark substances, ranged from one second to many hours, and this mechanism was called persistent phosphorescence or persistent luminescence, to distinguish it from the other two mechanisms.
