Tools of the Astronomer

A few years ago, astronomers' telescopes, astronomers did not have the advantage of a telescope. You can only observe with the naked eye. It was the first time Galileo made a better telescope to observe the universe for the first time. Most of the telescopes you buy today are better than the telescope he uses. These telescopes generally revolutionized astronomy. When Galileo first saw the sky picking up the telescope, he saw something wonderful. He saw a crater on the moon, a black spot on the surface of the sun, and a small satellite around Jupiter.

Galileo, a letter that plays a central role in the drama of the same name is a scientist considered to be the invention of a telescope representing the spirit of science. Telescope is a tool used by astronomers to examine the facts of tomorrow's body and its movement. It is a window for scientists to get objective knowledge of the world. It opposes superstition, blind faith and ignorance, and religious orthodox representing the present situation. What Galileo did with the telescope was the key to understanding the conflict in the play. Tension is the relationship between science and the telescope represented by Galileo, the relationship between the religious Orthodox represented by the Church and the relationship between the different groups of the Church.

Spectroscopy is one of the most important tools for astronomers to study the universe. In this chapter we will explain the basic items including various types of spectrometer from ultraviolet to near infrared. Focus is on the fundamental principle of the spectrometer and how to use the trade-off with the design of the observation experiment. Then, it introduces observation and reduction techniques, point out that some standard practices for plane expansion tend to reduce the quality of data rather than actually improving the data. Although the focal point is in the point light source, the spatially resolved spectrum of the extended light source will also be briefly explained. In order to provide the fundamental knowledge necessary for acquiring optimum data to the spectro-logist, the differential absorbance, the dense effect, the multi-target method, the optimal extraction, the plan considerations, and the determination of the radial velocity and the velocity dispersion This section explains.

Vienna's displacement law is a tool that astronomers and other scientists use to determine the peak wavelength of object emission. Since each wavelength in the visible spectrum has color, this can give clues about the color of the object perceived by the human eye. This law determines the peak wavelengths of radiation from various objects, from firewood flames to incandescent bulb elements, heat radiated from the human body, stars in the deep cosmos. If you think hell's fire is actually a fire, you can use it to determine the peak wavelength of the hell's fire radiation and therefore you should be able to describe that color.
