Review -  In the previous part of the blog I told you about the facts and circumstances related to the Wonders of the Midnight Sun where the factual description is based on behalf of the facts - Preface and Geographical phenomena dealing with the scenerio of the Midnight Sun having relationship with Earth and Earth Axis.

 In the second part of this blog I would like to confess with you about the scientific facts and phenomena dealing the natural phenomenon of the Midnight Sun - 2 

Scientific Facts and Circumstances - I

Midnight Sun scientifically causes when the rays of the sun that produced the short-wave radiation energy keep consistently moving from north to south during the precise period of summer solitice.

According to the systematic view of nature, the phenomena of Midnight Sun periodically occurs in the delightful nights of northern and southern hemisphere which can be known as Polar Nights - These nights are appear in the reverse mood of direction of the polar day duration. 

While dealing with the natural phenomenon, Polar Nights time & duration starts from the dry days of winter season of the cold climate respectively. While it is important to note that geographical areas effected by the polar nights are comparatively smaller than that of those nights appear in the midnight sun. 

Astronauts are of different opinions regarding the concept of the polar night research and evaluation as they classified the polar nights into four types -  Polar Twilight, Polar Civil Nights, Nautical and Astronomical Polar Nights. 

The sun goes under the horizon of all day long during its appearance is visible in the Polar twilight nights whereas a source of faint glow of light has been perceived by observer during the midday duration which reflecting in the sky of twilight civil polar nights and the sun is visible approximately between zero to six degrees as under the horizon. 

In the same context, the sun determine a efficient role in terms of appearing in the Nautical Nights of the polar region that the sun is less visible even there has been observed no other trace of light apart from around the midday interval of time although the sun is visible at twelve degree lower pass below the horizon during these nights. 

Nevertheless, in the astronomical polar night the sun is moving across the horizon of Arctic Circle around at a distance of twelve to  eighteen degree that passes below the horizon this sequence is only visible during midday duration of around 24 hours. No any other trace of light has been seen or occurred due to the continuous fall of night.

Scientific Facts and Circumstances - II  

In addition to the quiet interval of polar nights the geographers and astronauts again researched and identify the sequences of White Nights has been occurred in the Antarctic areas. The appearance of the white nights has been experienced by the viewer in a specific period of day time & duration of twilight instead of the Midnight Sun.

Nonetheless, during this duration of the time, the sun passes away below the horizon around at a distance of less than six to seven degrees above in the sky. The White Night are never dark and lighting sufficient during night. These night are regarded as White because the sun sets at the real time of its duration and the remain nights appeared with no darkness  this sequence is only o visible in the high latitude regions of the Antarctica.
