Night sky

It is no secret that the night sky is a magnificent sight as well as a curious space filled with science. So let's look at the night in which we can observe this night.

There is a large number of observations in the night sky. Stars, planets, moon, comet, meteorites, meteor shower, star clusters, star clusters, nibulae, galaxies, artificial satellites, sub-planets.

Objects that can be observed by the naked eye without a telescope.

1. Planets

Mercury, Venus, Mars, Jupiter, Saturn

2. Gelatinous

Eg, the Andromeda galaxy, the Milky Way

3. Nebas

Eg - OrionNebula

4. Star clusters

Eg - to make the stars happy

5. Moon, precursors, meteors, satellites, stars, constellations of constellations

But for further study of these objects, a telescope should be used. Specifically, when there are galaxies in the night sky, all the stars that we see are of the Milky Way galaxy we own.

Star constriction

As you have heard, a number of stars can be thought of only as a kind of object or object of stars. But in fact, according to the definition of the International Astronomical Union, a number of stars are "one area in which the asterisks are internationally recognized with definite boundaries. "These stars, of course, have different shapes. Also, there are different size constellations with different numbers.

The ancients had a night sky of 48 constellations. Later, in 1928, the International Astronomical Union added more than 40 stars to the number of constellations.

The relation between the sky of the stars and the motion of the earth

When observing the sky in the night sky, the constellations of the constellations were lowered from the west. For this reason, the ancients thought that the earth's constellation is rotating around the earth according to aquaculture. But it does happen because the planet revolves around its axis. Especially, our country, a cohesive country, can clearly see the incident.

By carefully observing the sky with the night time, the constellation of the constellation of the constellation of the zodiac will enable us to observe the constellations of the stars except in the same time as the sun and its vicinity. However, when observing the moon for several months, the number of stars in the same location is different from time to time in different months at different times.

For example, if you observe the cluster of stars in the eastern horizon at 9 pm, and then go back about a month later at 9 o'clock at 9 pm, if you observe the magnitude of the eastern horizon, you will see dozens of stars that we saw a month ago and many other stars. Also, a month before the horizon of the eastern horizon, the constellation of the constellations in the eastern horizon. This event is a phenomenon that occurs around the sun around the sun. As the planet moves around the sun, this is how the new constellations of the stars gradually appear from time to time. This is a testimony to the fact that this solar center is correct.

If you observe the sky with such a night and night, you will be able to clearly understand the Earth's spin and revolution and the constellation of the earth.

In this case, the celestial object is called the Phenomenon-Daily Motion, on the one day in the East, at the same time descending from the west. This is due to the earth rotation (circling around itself). At the same time, at the same time, in the positioning of different constellations of the number of stars (star) during the same period, the phenomenon of change is called -actical- motion. This is because of the Earth's renaissance.

Preparation for observation

1. To find a suitable place for observation, Most of the heavens that do not interfere with the surrounding trees should be a place of light (free from light pollution) that is visible outside light. And it must be a place of injuries such as insects, snakes, thornbushes.

2. Before doing this, observe the equipment, paper, pencil, star maps, and prepare the red light torch.

Getting to the dark

Before a good observation encounter begins, darkness must be acclimatized. It takes about 15 to 20 minutes to reach the darkness from the light and darkness. When we are in the dark, the earthing hole reduces the light entering the eye's eye. But when it comes to darkness, the aperture is enlarged and the eye tries to insert more light. Further, the sensitivity of the sensitivity to the sensitivity of the sensitivity to the light is increased, and the sensitivity to the asbestosis increases. That's why it takes about 20 minutes to adapt to the darkness. In this case, the eye gets blue, yellow and green, except for the red color, which immediately accursed to the light. This is because the blind eye is more sensitive to those colors. This blue color is the highest sensitivity. Here again, it takes 15 to 20 minutes to get familiar with the darkness of the eye. Therefore, such colors should not be used when observing. In the dark, however, the eye is less sensitive to light. Therefore, when the night sky observes, light should be used when we use red light. The darkened eye can not escape it.

For the first time, when watching the night sky, you do not need to use the star map. Firstly, what we do in the night sky should be tried with a star-studded eye without a star map. The telescope is used by telescopes for successful observations
