A person is so used to the change of day and night that he already accepts this phenomenon as ordinary. However, how many interesting questions can arise in his head if he rejects the usual opinion and tries to look at the world from a completely different angle. Indeed, in reality, earthly night is an amazing phenomenon that has given rise to many laws.
So let's go on a short trip through our universe and finally find out how unique it is. In particular, let’s talk about exactly what role night plays in the life of our planet.
What is night?
Night is a physical phenomenon caused by a partial absence of light. This happens because the Sun is on the back of the planet, because of which its rays do not fall on part of the surface of the Earth. The funny thing is that even at night our planet is not devoid of all the light, otherwise people simply could not see anything beyond their nose.
It should also be noted that night is a rather relative phenomenon. Its duration can vary greatly depending on the time of year and geographical location.
What could be the night?
So, as mentioned earlier, night is an amazing phenomenon that has many forms and types. The simplest example would be the presence or absence of the moon and stars in the sky. However, there are nights that are completely different from others that can enchant a casual spectator.
So, the most beautiful is the polar night. At the edges located in extreme latitudes, twilight is much longer. At times, dusk can last a whole day, only occasionally retreating over the horizon. But it is fascinating that precisely at such moments here you can see the northern lights, illuminating the sky with hundreds of different colors.
The exact opposite is white night. So, in temperate and high latitudes during the summer solstice, even at midnight, the world can remain as bright and clear as day.
