kids, even at preschool age, often asked the question: "What is heaven?" And sometimes adults simply can not fully answer it, although they understand the meaning and the essence of the word.Well, try to understand this term and uncomplicated from a scientific point of view, but still understandable language to describe this substance.
What is the sky in a broad sense?
As every earthling, the sky - this is the panorama that opens before us every day.It is air space, which consists of multiple layers of the atmosphere are different in their density.In this space, there may be various physical and chemical phenomena.Among them distinguish the formation of clouds, snow and storm clouds, lightning, northern lights, rainbow and so on. It should be noted that on Earth the sky could be the night, morning, afternoon and evening.Depending on the time of day changing its color and lighting, which is provided exclusively by the Sun (as the rest of the cosmic bodies or located too far from the Earth, or do not have enough for the desired lighting brightness).
Physics and Astronomy Theory sky
Now consider what the sky at us with a scientific point of view.According to the space, in fact, called the visible part of the space, which is observed with certain celestial body.Modern science has given are not new concepts such as Earth's sky, Martian, Lunar and so forth. In short, being on the surface of each solid celestial body (Mercury, Venus, Earth and the Moon, Mars, Pluto), you can see the sky.Only on each of these planets, it will be great, because the atmosphere that paints it in a certain tone is quite different.In turn, depending on the molecular composition of a particular atmosphere, there are also a variety of processes in a given "sky."The atmosphere of Mars is full of microscopic metal compounds, which is why it has a reddish color.On this planet, there are sharp differences of temperatures, frequent meteor showers, since the thickness of the atmosphere all it's missing from outer space.
sky that we see on his planet
quite another matter - the sky and the Earth, that is, the atmospheric envelope of our own planet.A large number of protective layers, the presence of molecular oxygen and sufficiently dense ozone layer provides protection from cosmic adversity.All phenomena that presents us with our sky is not as destructive as on Mars.That is why through the dense layer of the atmosphere is rarely tested meteorites (if they are - it is equivalent to a catastrophe of global significance), to us does not reach interstellar dust, the temperature of which is over a thousand degrees Kelvin, we are not afraid of extreme temperatures, depending on solar activity.
Typical earthly heaven
That is the sky from an astronomical point of view, we have talked, now let's try to understand how it is seen residents of certain latitudes of our planet.As a rule, the cloudless skies and clear day in all regions of the world appears to us blue.The sunny day, the more saturated look of our natural environment of the Earth.White light clouds of heaven do paler tone, as if the artist shed white.This is a regional difference, as all the clouds are located strictly locally and fairly low over the surface.Changing the color of the sky always in all parts of the world, depending on the time of day.In the morning, at sunrise and at sunset the sky is painted in pink, purple, yellow and even green colors.After that, the night sky gets dark blue tone, and (if there is no cloud cover) slightly distant light illuminated stars and the moon.
our closest companion - ever-changing Month
interesting fact, but the sky, the photo is made at night in equatorial latitudes, different from the panorama that unfolds over the regions closer to the poles.It depends on the closeness of all the heavenly bodies that can be seen with the naked eye, to the surface of our planet.The first increases the Moon, its glow becomes brighter, all the craters and oceans which can be seen more clearly.Also worth noting is that it is on the equator, such a thing as a blue or blue moon occurs more often than in our latitudes.That is why the comic track the movement of bodies, astronomers prefer this position.
What the heavens and what is their point?
With the advent of scientific terms arose and religious judgments based on accurate knowledge.Since blue panorama that unfolds before us infinite and majestic, it began to magnify the skies all the representatives of the Christian religion.Heaven - a marina bliss, serenity, strength and inspiration.They live angels, they are staying all souls experiencing reincarnation.
