Over the years, there have been several cases of curious and bizarre sightings of light beams seen by people. While some have a perfectly plausible explanation for their appearance, most of these phenomena go unexplained. Here are some of the exciting such occurrences over the past century that are sure to appeal to the UFO enthusiast in you.
St. Elmo Fire
When sailors came upon a kind of bluish light that emerge from the ship masts during night occasionally they named it St Elmo’s Fire taking it as a good sign as the light didn’t bring any harm to the ship. According to Steve Ackerman, an atmospheric scientist there seems to be an explanation behind this effect. He claims that thunderclouds form an electric field due to the difference in electric charge between the ground and cloud, which is further, intensified in case of pointed objects such as the ship’s mast or an electric pipe.
A plasma glow identical to St. Elmo’s Fire can be created inside a laboratory. The LED lights that are now replacing the earlier lighting systems are considered a miraculous invention (though not on the level of the amazing lights discussed above ) due to the energy and money saving effects they provide, and because they can be used to help grow plants, check out this site for more info.
These lights are formed due to shock waves produced by rocks under stress. The rocks form a plasma discharge that makes you feel electrified and gain a halo around you like in a saint. But this light doesn’t harm you although you may feel a little bit funny. The presence of CCTV cameras has made it possible to capture this light.
While earlier this light was considered as mythical, it has now been proved a real light. The lightning bolt that strikes the ground from a cloud can lead to vaporization of certain minerals leading to the ball of light seen. The light is actually formed due to the presence of silicon components in the light.
These lights although seen occasionally, serve to spur an interest in the onlookers . It is such phenomena that have led scientists to study further on the light spectrum leading to advanced systems such as infra red beams and the LED lights, which are now used in all spheres of our life. The plasma grow lights at Plantzoid.com are revolutionary products that help grow plants in a better way and save money too.
Sunset and green flash
Just before you witness the Sun go down, you can see its light turn a green color. This is not real change of sunlight but just a mirage. Mirages can also turn the sun into a shimmering wave pattern. This effect is due to the splitting of the white light in the sun into different colors. The blue color in the sky is due to the effect of the blue rays being scattered by the atmospheric gases. The red light falls beyond the horizon and is the first to disappear followed by orange and yellow. The green color is the last one to be seen as the Sun goes below while the blue, violet and indigo are scattered. Although this mirage is very slight it can be seen best in ocean horizons.
