Ball Lightning Phenomenon
Collective information about ball lightning phenomena which is rare but mostly filmed and represented as "UFO" or "aliens" since early 70's & 80's and it has been known since the early 1900's.
Ball lightning is an unexplained phenomenon described as luminescent, spherical objects that vary from pea-sized to several meters in diameter. Though usually associated with thunderstorms, the phenomenon is said to last considerably longer than the split-second flash of a lightning bolt. - Source: Wikipedia
What causes ball lightning? The Lanzhou researchers' paper supports the theory that ball lightning results from a ground strike that creates a reaction between oxygen and vaporized elements from the soil. This ionized air, or plasma, is the same condition that enables St. Elmo's Fire, the stationary glow that is sometimes confused with ball lightning.
The presence of glass may generate ball lightning, according to another theory published in 2012. Atmospheric ions could pile up at the surface of a window, producing enough of an electrical field on the other side to generate a discharge. Another study, published in 2016, suggests that microwave radiation produced when lightning strikes the ground could become encapsulated in a plasma bubble, resulting in ball lightning. - Source: National Geographic
Ball lightning, also called globe lightning, a rare aerial phenomenon in the form of a luminous sphere that is generally several centimetres in diameter. It usually occurs near the ground during thunderstorms, in close association with cloud-to-ground lightning. It may be red, orange, yellow, white, or blue in colour and is often accompanied by a hissing sound and distinct odour. It normally lasts only a few seconds, usually moving about and then vanishing suddenly, either silently or explosively. Ball lightning has been reported to cause damage by burning or melting but is usually harmless. Its causes and its relation to common lightning are not known, but among the suggested explanations are: air or gas behaving abnormally, high-density plasma phenomena, an air vortex containing luminous gases, and microwave radiation trapped within a plasma bubble. Sometimes bead lightning is mistaken for ball lightning. Bead lightning is most apparent when the current in a cloud-to-ground flash persists for an appreciable fraction of a second. In these cases, the luminosity also persists and the channel may have regions of enhanced luminosity that resemble a string of beads. - Source: Britannica
Our miraculous planet full of mysteries and wonders however ignorant majority prefer to call everything "aliens" from Pyramids to natural phenomenon. Scientists, biologists and researchers know more about the surface of a dead rock called Mars than our own oceans. Only the %5-10 of our oceans discovered; how deep the abyss goes and what kind of amazing creatures living there is a complete mystery alone.
