DARK LIGHTNING Meaning and
Definition
-
Dark lightning is a phenomenon characterized by the sudden and intense release of radiation in the form of extremely high-energy particles, such as electrons and gamma rays, during thunderstorm activity. Contrary to its name, dark lightning does not emit visible light, as it occurs within thunderclouds and is not directly observable to the naked eye. Rather, it generates bursts of non-thermal radiation that are primarily composed of gamma rays, which are highly energetic electromagnetic waves.
This unique type of lightning is believed to be produced through the interaction of powerful electric fields within thunderstorms with high-energy particles, such as electrons and positrons, present in the Earth's atmosphere. As these electric fields rapidly accelerate the charged particles, they generate intense bursts of radiation known as dark lightning.
Since dark lightning does not emit visible light like ordinary lightning, it poses a particular challenge for detection and observation. Nevertheless, advanced detection instruments, such as the Fermi Gamma-ray Space Telescope, have been able to measure and capture signatures of dark lightning occurrences. These measurements have increased our understanding of the physical processes involved in thunderstorm dynamics and the complex interactions between electric fields and charged particles within thunderclouds.
Given its potential to produce hazardous levels of radiation, dark lightning presents a concern for aircraft and astronauts in flight. Research efforts aim to further investigate this phenomenon in order to enhance tools for monitoring and predicting its occurrence, ultimately ensuring the safety of those potentially exposed to its effects.

Etymology of DARK LIGHTNING
The term "dark lightning" was first coined by Joseph Dwyer, a physicist at the Florida Institute of Technology, in 2012. However, the word's etymology can be broken down as follows:
1. Dark: The word "dark" originates from the Old English word "deorc", which means absence or partial absence of light. It has been used to describe situations or objects that lack illumination or are concealed from view.
2. Lightning: The word "lightning" comes from the Middle English word "lightenyng", which has roots in the Old English word "lichtening". It refers to the electrical discharge that occurs during a thunderstorm, characterized by a bright flash and the accompanying sound.
Hence, the term "dark lightning" describes a phenomenon where bursts of gamma rays are emitted during a thunderstorm, but they are invisible to the human eye.
