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.
Astronomers use spectroscopy to collect information about star composition. By observing the light emitted by stars, scientists can analyze the spectral lines to determine the elements present in a star, providing insights into its chemical composition. This data helps astronomers understand the evolution and behavior of stars in the universe.
The 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 do scientists use to break visible light from a star into its component colors a telescope or a spectroscope?
Scientists use a spectroscope to break visible light from a star into its component colors. This instrument is specially designed to observe and analyze the spectral lines produced by different elements in the star's atmosphere, providing valuable information about its composition and physical properties. Telescopes are used to collect and focus the light, while spectroscopes are used to disperse and analyze it.
What can electromagnetic spectrum tell us about a star?
The electromagnetic spectrum of a star reveals important information about its temperature, composition, and evolutionary stage. By studying the different wavelengths of light emitted by a star, astronomers can determine its surface temperature, size, age, and chemical composition, providing valuable insights into its nature and behavior.
What can you find about a star when using telescope?
When using a telescope, you can observe a star's brightness, color, size, and distance from Earth. Depending on the telescope's capabilities, you may also gather information about a star's temperature, composition, and movement through the sky.
What can spectroscopy be used for?
Spectroscopy can be used to study the interaction between matter and electromagnetic radiation. It can be used for chemical analysis, identifying compounds, determining molecular structure, and studying the properties of materials. Spectroscopy is also used in astronomy to analyze the composition of celestial objects.
Do scientists use stellar parallax to determine a star's temperature?
No, scientists do not use stellar parallax to determine a star's temperature. Stellar parallax is a technique used to measure the distance to stars by tracking their apparent shift in position as the Earth orbits the Sun. A star's temperature is typically determined by analyzing its spectrum, which provides information about the star's composition and temperature through features such as absorption lines.
Instrument used to collect important information about star's composition from the earth?
Spectroscopy is the instrument used to collect important information about a star's composition from Earth. By analyzing the light emitted by a star, spectroscopy can reveal the star's chemical elements and their abundance.
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.
How do scientist determine the composition of a star?
Scientists determine the composition of a star by studying its spectrum, which is produced by analyzing the light emitted by the star. By examining the absorption lines in the spectrum, scientists can identify the elements present in the star's atmosphere and infer its overall composition. Additionally, measurements of the star's temperature, luminosity, and mass can also provide valuable information about its composition.
What does the presence of molecular bands in the spectrum of a star indicate?
The presence of molecular bands in the spectrum of a star indicates the presence of molecules in its atmosphere. These bands can provide information about the composition and temperature of the star's atmosphere, and are used to study its characteristics and evolution.
What do scientists use to break visible light from a star into its component colors a telescope or a spectroscope?
Scientists use a spectroscope to break visible light from a star into its component colors. This instrument is specially designed to observe and analyze the spectral lines produced by different elements in the star's atmosphere, providing valuable information about its composition and physical properties. Telescopes are used to collect and focus the light, while spectroscopes are used to disperse and analyze it.
What are characteristics used to classify a star?
you classify stars by color, temperature, size, composition, and brightness.
What are the other instruments used by astronomers in gathering information about stars?
Astronomers use instruments such as spectrometers to analyze starlight and determine a star's chemical composition, temperature, and motion. Telescopes are used to observe stars and capture images at different wavelengths. Interferometers combine signals from multiple telescopes to create high-resolution images of stars and star systems.
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 can electromagnetic spectrum tell us about a star?
The electromagnetic spectrum of a star reveals important information about its temperature, composition, and evolutionary stage. By studying the different wavelengths of light emitted by a star, astronomers can determine its surface temperature, size, age, and chemical composition, providing valuable insights into its nature and behavior.
What instrument used to gather information about star?
Telescopes?
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.
