Scientist study the spectra of stars using an instrument called a spectroscope. A spectroscope spreads light into different wavelengths. By using these spectroscopes astronomers can study stars characteristics( temperatures, compositions and energies).

∙ 12y agoSpectroscopy is used in astronomy to learn what is happening in stars etc. By studying electromagnetic waves radiated from nuclei, one can learn a lot about the shape and activity of a nucleus. This helps us understand why certain reactions in stars happen. It is also used to identify nuclei. Every nucleus is has a unique decay scheme, which is always the same, eg some nucleus decaying to a ground state via a 200keV gamma ray, will be observed in all nuclei of the same mass and proton number.
If these gamma rays are observed, this means 12C is present

Is an instrument used by astronomers to study heavenly bodies and is used to determine the composition of the heavenly bodies through their color patterns?
Spectrograph.
How could caravans passing through Babylon be helped by astronomers?
Astronomers help because they can help measure the time, or what day it is for the caravans.
How could passing through Babylon be helped by astronomers?
Astronomers invented the sun dial. They could help by assisting the caravans with their time managements and how many hours they had until the night came.
Indian astronomers recognized that earth?
India astronomers recognized that the earth was a sphere.
What are the release dates for We Are Astronomers - 2011?
We Are Astronomers - 2011 was released on: USA: 3 November 2011 (Virginia Film Festival)
What space gadgets is used by astronomers?
telescopes, spectrograph's, screw drivers, and lots of Physics!
Is an instrument used by astronomers to study heavenly bodies and is used to determine the composition of the heavenly bodies through their color patterns?
Spectrograph.
What part of a star is it that astronomers study in order to learn its characteristics of a star?
Primarily, it's spectrum (it's light seen through a spectrograph).
What does it mean when an astronomers observing starlight wa spectrograph notices shift at off lines to the red end of spectrum?
The star is moving away fro where it is. ~Justine... :))
What does a spectrograph help determine?
The elemental composition of the materiel forming the spectrum.
Instrument used by astronomers to spread light?
A spectroscope is used to diffuse the light from a star into its spectrum, so that astronomers can analyze the elements that make up the star. The same sort of instrument can be used to analyze the elemental composition of ANYTHING; for terrestrial uses, the instrument is called a spectroGRAPH.
How does a spectrograph provide information about stars chemical composition?
A spectrograph is an instrument for chemical analysis.
What instrument do the astronomers use to determine the chemical composition of a star?
They use a spectrograph to pass light through a prism to break it the light waves into its constituent colors. Then by looking at what colors are missing they can determine both the temperature and composition of the star.
What is the difference between Aston's mass spectrograph and Dempster's mass spectrometer?
what is difference between mass spectrograph and mass spectrum
What do variable stars help astronomers measure?
Distance.
What 3 properties do telescopes have thataid astronomers?
Telescopes focus on certain objects that are not visible from the naked eye, they help astronomers develop new theories because they are able to see more, and they are instruments that help astronomers prove theories true/false.
Why do scientists use a spectrograph?
because they want to
