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.

How are elements like fingerprints?
Each element has an unique set of attributes, just like fingerprints. One of the most common attributes of elements used is its spectral signature. When an element is excited, it emits photons on specific frequencies. These frequencies can then be used to map things such as the chemical composition of distant exo-planet atmospheres or moons, such as Titan.
Contribution of chemistry to astronomy?
- determination of the chemical composition o f our planetary system (Sun planets) - determination of the composition of stars - determination of the composition of comets and meteorites - identification of chemical compounds in the universe Some branches of chemistry are involved: cosmochemistry, spectrometry, chemical analysis.
Why might astronomer would most likely use the principles of chemistry?
An astronomer would use the principles of chemistry to determine the chemical components of distant planets and stars. The most useful discipline is that of spectral analysis. This is the identification of chemical compounds by their actions on various wavelengths of light.
Did distant relatives by nas and Marley go platinum?
Yes, it did.
How long has sodium been used?
Humankind's taste for sodium reaches far back into the distant past
How do astronomers determine the composition of distant celestial objects?
Spectroscopy is the systematic study of spectra and spectral lines. Spectral lines are used to provide evidence about the chemical composition of distant objects. So the answer to your question is through spectroscopy.. not spectrometry like the previous editor posted.
What are the methods that astronomers use to identiy the composition of distant stars?
Spectroscopy.
What is the name for the chemical messengers in blood that control distant organs?
Hormones.
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.
How information is transferred from distant atoms to atoms here in earth?
Protons
How does light help us see?
It carries information from distant objects to our eyes.
How are spectrums used to study?
Astronomers use the light spectrum of distant objects to determine the chemical composition of those objects. Each element on the period table gives off a different spectrum, and by looking through a spectrometer an astronomer can read the spectrum and figure out what that object is made up of to gain better understanding of our universe.
What are the distant threadlike structure that contain the genetic information of the cell?
DNA, which is contained in the nuclueus. :)
How is the electromagnetic spectrum used in outer space?
The light from very distant stars may be seen and analysed for elemental composition. Similarly with the microwave radiation from the Big bang.

How do get information about distant planets?
Send a probe or alalyse the light they reflect using optical telescopes.
How can information can flow to and from the distant parts of the body and then back to the brain.Briefly summarize how information can flow to and from the distant parts of the body and?
The nervous system is designed to work both ways. Since the cells can only operate one way, this means that there is two complete systems.
