scientists can tell the stars composition and temperature from its spectrum.
Hope tht helps :]

Observation of the shift of a stars spectrum toward the red or blue enables us to determine the stars?
The star's velocity (away from us, or towards us).
What do the bright lines in a bright light spectrum tell us?
to identify elements
Spectrum gives the what of the star's gases?
An absorption spectrum can tell the astronomer or physicist what elements are in the starlight being observed. A diffraction grating is used to split the incoming light into a spectrum of colors. Sodium, for example, causes dark Fraunhofer lines at known points in the visible spectrum. Helium was discovered in the solar spectrum by Bunsen and Kirchoff using this technique. Hence the name derived from Helios for the Sun.
What can be analyzed by a stars light spectrum?
Its elemental composition.
How does the light that astronomers see from distant stars and galaxies tell htem that the same atoms with the same properties exist throughout the universe?
We determine the types of elements contained in the star or within the corona by analyzing the spectrum of the light we receive. Each element will radiate at a set of specific discreet frequencies, and the frequencies they radiate tell us what the element is, and how deeply ionized it is. The spectral analysis is exact; we can even determine the proportions of the elements that we see by the relative brilliance of their light. But there IS one thing that the spectrum cannot tell us; is this a normal matter star, or an anti-matter star?
The light from stars are used to determine what?
The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.
What can a scientist learn about from a stars spectrum?

What can a stars spectrum tell astronomers about a star?
What elements the star is made of.
What can a stars spectrum can tell astronomers?
What makes up the star or element.
Observation of the shift of a stars spectrum toward the red or blue enables us to determine the stars?
The star's velocity (away from us, or towards us).
What does the blue shift mean in regard to stars and galaxies?
Light is a spectrum. On one end it is red and the other blue. We see light in this spectrum as waves and if it is blue, the object is coming toward us. If the waves are red than it is moving away. The frequency of these waves tell us how fast and object is moving toward or away from us.
Which type of spectrum is associated with the radiation of most stars?
absorption spectrum
Which part of the electromagnetic spectrum generally gives us your best views of stars forming in dusty clouds?
Infrared
What do the bright lines in a bright light spectrum tell us?
to identify elements
How can a stars spectrum be different from another stars spectrum?
The differences in spectrum are mainly due to: * Differences in temperature between the stars * Differences in chemical composition * Differences in relative movement (redshift / blueshift, due to the Doppler effect)
How can spectrum tell us if an object is reflecting blue light from a star?
how can you tell if an object is reflecting blue light from a star
