Small dots and long distances, but not an obstacle in front of the human mind ((radio astronomy))

Small dots and long distances, but not an obstacle in front of the human mind ((radio astronomy))

Always troubled the minds of man there in the sky remained at a loss and there were many theories about how deal with the universe and what is only his germ
There were many obstacles Distances are many and large sizes so what scientists Ptlscobathm see happened long ago and ended!!!!!!!
With the development of human science to reach to what he can from this study bulky and reach: Radio Astronomy:

 

Under light puzzling to scientists came to be Isaac Newton discovered in 1666 that decomposes white light beam to the colors of the rainbow (the visible spectrum) when it passes in a glass publication
The explanation that the light from the sun or from any other light source consists of waves of different frequencies that vary the speed of each of them when they pass in the center of the thickest of Vtnksr air and graduated in groups according to their frequencies. This means that each center break light a certain way (for example, absorbs blue and reflects other colors) Vtstqubl eye colors reflected, she believes the body color.

 

 

 

With the development of science and technology have evolved methods of measuring the wavelength and frequency of the lights emitted from various sources (stars and galaxies) by a spectrometer and a spectral analysis.
For example, stars and galaxies emit radiation consists of a specific set of frequencies characteristic of each element its own frequencies

And so scientists can study distant stars and see installed

 

Fraunhofer lines

Note the German Fraunhofer 1814 and no black lines in the sun's atmosphere he knew that there are elements in the sun's atmosphere absorb light from the guest

And select locations of these lines of the whole spectrum possible appointment wavelengths of lights that disappeared from the sun's atmosphere during its journey from the surface to the ground.

Since the elements in the universe perspective and one which is in the periodic table of possible knowledge of the items in the sun's atmosphere because it is identical to those on the ground, but the size of the largest
Note: The universe perspective (with all its billions of galaxies and stars) is 4% of the entire universe and the rest black matter and energy do not know anything about it

 

Similarly send radio some Moajat stars are received and analyzed by the hardware
Thus no longer the stars small glowing points of light, but celestial objects Stern has its advantages that are unique and with the development of science evolved tools used in the analysis of radiation
Astronomy became Alradboi indispensable branch of the branches of Astronomy
