Inexplicable phenomena, definition and study. A-Z index of Cognitio.

The term phenomenon refers to all that is observable through the sensitive apparatus. In common language, the term is used in reference to any particular subject matter studied and also in the sense of what appears to be beyond the ordinary. Phenomenon is any observable event.

Phenomena are the study objects of science. You can group all the phenomena of a certain field under a more specific denomination, and get, for example, starting from all the events that have to do with optics and light the category of optical phenomena. Some events are observable by anyone, others require complicated manipulations and sophisticated equipment. There are some terms in the field of phenomena, the most important are two:

Physical phenomena: it is a transformation that does not change the nature of matter.

Chemical phenomena: is a transformation that changes the nature of matter.

Among the many Inexplicable phenomena we find:

Sun dog

Sun dog

Sun dog

The perihelion (commonly known as “solar dogs”) is an atmospheric optical phenomenon due to the refraction of sunlight by small ice crystals suspended in the atmosphere and which usually constitute cirrus. Are spotted as bark shorts at the same height as the ice crystals align preferably in a roughly horizontal direction, according to aerodynamic drag effects. Although they are often much less vivid and widespread than the ones shown in the picture, are actually quite common, but they often escape sight because they need to look in the direction of the real Sun to identify them.

The Paraselene

The Paraselene

The Paraselene

Is an atmospheric optical phenomenon that consists of the appearance of 22 ° light spots on the right and / or left of the Moon, commonly known as lunar dogs. It is due to the refraction of lunar light by ice crystals of hexagonal shape present in the clouds called cirrus. it is a phenomenon similar to perihelion but it is more rare because the moonlight is weaker than that of the Sun and to be produced it is necessary that the moon be full or almost.

Ignis fatuus

Ignis fatuus

They are usually blue flames that appear at ground level in particular places such as cemeteries, marshes and ponds in the moors. The best time to observe them seems to be on the hot August nights. Legends about fake fires are so many. In antiquity, they were seen as demonstrating the existence of the soul. Some northern people’s, on the other hand, believed that following them would be their destiny. The ancient Egyptians, on the other hand, believed that one person had been “good” in his earthly life, the more his Ach (the Light, part of the soul of a person according to Egyptian religion) was illuminated, giving rise to what we now call Ignis fatuus.

Globular lightning

Globular lightning

Globular lightning

A globular lightning is a rare, sometimes very short, and particular bright atmosphere of the atmosphere. It is a small bright globe, of spherical shape and of variable diameter, fixed or, more frequently, in rapid and random movement. It can be seen both in presence and in the absence of thunderstorms. This curious atmospheric phenomenon is still scarcely understood today; of all the energetic manifestations that take shape in the troposphere is still one of the most mysterious despite being studied for centuries. 

Red sprite

Red sprite

The red spectrum is an atmospheric electrical phenomenon that is still under study. It manifests itself in the high layers of the atmosphere, even up to 80 km of altitude, more precisely above the thunderstorm, usually associated with the ionization of the air. It is rarely visible to the naked eye. Scientists have already installed many cameras on high-altitude mountains in the hope of immortalizing the red spectra. With the construction of the new International Space Station, more in-depth research on these phenomena will be conducted, with the hope of responding to many unresolved issues.

Earthquake lights

Earthquake lights

Earthquake lights

The lights also known as the EQL sign are an unusual optical atmosphere phenomenon, similar to a boreal aurora characterized by a brightness that appears in the sky above or in the vicinity of areas with tectonic stress, seismic activity or volcanic eruptions . They are visible especially during the night. Chronicles of the past have described the presence of such lights, but for a long time have been considered a myth. Seismologists established their existence when they were photographed in Japan at Nagano during the Mitsushiro seismic swarm between 1965 and 1967.

These phenomena are still not fully explained, and it is not excluded that they may be of unknown nature such as UFOs or extraterrestrial phenomena.
