The thing is that countless stars are in different stages of a stars life. They observe and report. But this all happened fue to 1 scientist's observation. Fraunhoffer had observed black lines in the sunlight which where so close to each other that they were not observed before. He concluded that elements which emit a particular spectrum also absorve that part of the spectrum. So some parts of the light which is formed in the interiors of the sun are absorbed by the unknown elements in the sun's atmosphere and thus you get the chromosphere's composition.
Now for the interior. Scientists have observed that stars are formed in hot gases and clouds of hydrogen. So they cocluded that the interior of the sun was composed of hydrogen.

∙ 11y agoThe Astronomers, that are scientists specialized on space issues, gather information about star and other celestial bodies by reading the most diversified books about this theme. Astronomy is a very ancient study and a huge quantity of information has been gathered along the time. Nowadays, they use mainly the internet to get inside of the most recent discoveries, provided mainly by NASA, which is the most important US governmental Institute that deals with the most varied subjects about space exploration.

What can spectroscopy be used for?
Analyzing the spectrum of a star, or galaxy, can provide some useful information, including the temperature of a star, whether a star or galaxy is moving towards us or away from us, and the chemical composition.
Analysis of the of a star reveals the composition of the star?
That's done by analyzing the star's spectrum.
What information does a star's spectrum offer about the star?
Spectroscopy shows what elements are present in the star, it's chemical composition. The different elements give off different energy signatures through radiation, which relate to the wavelength and therefore colour.
How are stars in the same star cluster simalar?
similar age and composition.
What is the meaning of a white-blue star?
It's a star that due to size and composition gives off blueish-white light.
Instrument used to collect important information about star's composition from the earth?
a. telescope b. space shuttles c. space probes d. spectroscope
Can a spectroscope be used to collect information about the chemical makeup of a star?
a spectroscope is the instrument used to determine the chemical makeup of a star.
What is sirius composition?
Sirius is a star, I hope this detailed information helps.
The spectral type of a star measure?
The spectral type of a star is what measures its chemical composition. The visible light that bounces off of it can be used to determine the composition.
What are characteristics used to classify a star?
you classify stars by color, temperature, size, composition, and brightness.
How did astronomers in the 19th century gather information about the chemical composition of stellar objects?
There is one way for gathering information about chemical composition of stellar objects - spectral analysis! Astronomical spectroscopy began with Isaac Newton's initial observations of the light of the Sun, dispersed by a prism. He saw a rainbow of colour, and may have seen absorption lines. The absorption lines in stellar spectra can be used to determine the chemical composition of the star.
What is the reasone for performing spectrum analysis?
It is used to analyse the state and composition of a distant star's light as it arrive on Earth.
What instrument used to gather information about star?
Telescopes?
The composition of a star can be identified by?
the lines in its spectrum
Can a scientist identify a star's composition by looking at its continuous spectrum?
the star's color
Suppose you want to know the chemical composition of a distant star Which piece of information is most useful to you?
A telescope, whose light output would be sent through a spectral analysis machine of some type. That analysis of the emission spectra of the star would be compared to the known spectra of the elements to find the composition of the star.
What can be said about the star composition if the spectrum of a star shows the same absorption lines as the sun?
If the spectrum of a star shows the same absorption lines as the sun than you know that the star has the same composition as the sun. This means that the star is made of the same elements as the sun.
