For example, since such charged masses can appear as visual, infra-red and radar targets, they could be useful as decoy targets, or as passive electromagnetic spectrum energy-absorbers. The authors recommend an investigation into the use of such plasmas for novel military applications. The report suggests that such objects are likely glowing plasmas resulting from particular natural configurations of electromagnetic fields. However, "the conditions for the initial formation and sustaining of what are apparently buoyant charged masses, which can form, separate, merge, hover, climb, dive and accelerate are not completely understood". The British Ministry of Defence (MoD) acknowledged in a summary report written in 2000, that unexplained luminous objects in the sky have occasionally been seen. The latter may contain subgroups that appear to drift in different directions across the sky. The number of orbs in a sighting have ranged from a single orb to hundreds forming large "flotillas". But many orbs are said to behave as if they are controlled by an intelligent agent.įor example, they sometimes change direction like an aircraft, or several appear to cooperate to form patterns in Meteors entering the earth's atmosphere, while others have been attributed to mundane human activity such as White or orange in colour, but red, yellow and green orbs have been seen as well. May be the result of clandestine research on control systems for creating and positioning the plasma balls.įor many years, mysterious luminous spherical objects, or orbs, have been seen in the sky. Plasma ball formations in the sky as well as some crop formations on the ground The orbs appear also to be used as pixels for drawing three-dimensional Glowing plasma in the atmosphere from a distance. This article discusses evidence that some orbs are made with covert technology which can create balls of Luminous orbs seen moving across the sky sometimes behave as if they are under intelligent control. You can also sometimes see pearlescent colours in clouds, which is fairly rare.Summary. As a result more of the blue light is scattered and deflected away allowing more red and yellow light to reach the Earth. This is because during sunrise and sunset, the Sun is very low in the sky and so light has to travel through more of the atmosphere. Cloud coloursĪt sunrise or sunset, clouds can take on a red or orange colour. This means that even less light from the Sun reaches the bottom of the cloud, giving rain clouds their intimidating appearance.īecause the tops of clouds have a constant source of white light, they are always white! If you are ever on a plane, look out the window when you are above the clouds, you will see that the tops of all the clouds will be a brilliant white. This is more prominent in rain clouds because the cloud droplets are bigger, thus scattering more light. When light is scattered in a cloud it usually is sent back upwards, or out to the sides of the cloud, making the tops and sides of the cloud whiter than the base which receives less light. So why are clouds sometimes grey?Ĭloud bases are often grey as a result of the same scattering that makes them white. If we consider that there are millions of water droplets in a cloud, the scattered light interacts and combines to generate a white colour. Smaller particles can scatter shorter wavelengths more efficiently, like those that are invisible to our eyes in the atmosphere, making the sky blue.īigger particles like water droplets within a cloud scatter all wavelengths with roughly the same effectiveness. The spectrum is shared with other types of wave, from really short x-rays and gamma rays to really long radio waves.Įach visible colour has a different wavelength blue light has the shortest wavelength at 400 nanometres and red light the longest at 700 nanometres. We can see the full spectrum when it is split up and spread out as a rainbow. Sunlight or 'visible light' can be thought of as a wave and a part of the electromagnetic spectrum. These scatter all colours almost equally meaning that the sunlight continues to remain white and so making the clouds appear white against the background of the blue sky. When sunlight reaches an atmospheric particle in the sky, blue light is scattered away more strongly than other colours, giving the impression that the sky is blue.īut in a cloud, sunlight is scattered by much larger water droplets. As light passes through a cloud, it interacts with the water droplets, which are much bigger than the atmospheric particles that exist in the sky. Clouds are white because light from the Sun is white.
