Same thing as local stars like the Sun are made of; predominantly hydrogen, which is being 'burned' through fusion into helium. We can determine this mostly from absorption or emission spectra, a characteristic 'signature' of the elements they contain. There is a class of star called a Wolf-Rayet which is mostly helium. One should note that, so long as the fuel being consumed by the nuclear processes has a nett output of energy they can continue to burn elements 'down' the Periodic Table.. but they consume subsequent elements faster and faster, getting less and less energy out of each, until they hit Iron (atomic number 26) at which there is no nett energy output. Our sun for example, once it is exhausted, long after it's a white dwarf, should end up as crystalline iron since its mass is not high enough to become a neutron star. For more information see the theory of stellar evolution, the supporting Hertzsprung-Russell diagram, stellar classification, and the proton-proton chain/CNO cycle.
What else can I help you with?
Why astronomers have difficulty looking at distant stars except?
Astronomers have difficulty looking at distant stars because while we have highly specialized telescopes, they are in constant contention with various other celestial bodies. In addition to this, the light of distant stars takes hundreds of thousands of years to reach us, making it impossible to get a current look at a distant star.
Do nearby stars have larger angles than distant stars have?
Yes, nearby stars generally have larger parallax angles than distant stars. Parallax is the apparent shift in the position of a star when observed from different points in Earth's orbit around the Sun. The closer a star is to Earth, the greater the angle of this shift, making it easier to measure compared to more distant stars, which exhibit much smaller angles due to their greater distances.
What is the main use of the telescope?
to see a distant objects..like stars..
How do you know what distant stars are made of?
Scientists can determine the composition of distant stars by analyzing their spectra. The light emitted by stars contains distinct absorption or emission lines that correspond to specific elements present in the star's atmosphere. By studying these spectral lines, scientists can identify the elements present in a star and determine its chemical composition.
What are not a reason that astronomers have trouble viewing distant start?
Astronomers do not have trouble viewing distant stars due to their brightness, as many distant stars are incredibly luminous. Instead, challenges arise from factors like cosmic dust obscuring light, the expansion of the universe redshifting light from distant objects, and limitations of current telescope technology. Additionally, atmospheric interference can hinder ground-based observations, but these issues are not related to the inherent brightness of the stars themselves.
When was Distant Stars created?
Distant Stars was created in 1981.
How many pages does Distant Stars have?
Distant Stars has 352 pages.
Which of the following is not a reason that astronomers have trouble viewing distant stars?
Distant stars give off less light
What is the true shape of stars?
Stars are distant suns, which are roughly spherical in shape.
Why astronomers have difficulty looking at distant stars except?

Distant radio sources that resemble stars?
quasars
How far are the most distant stars from earth?
2
Who first realized that stars were distant suns?
an ancient greek philosipher named Aristotle first developed the theory that stars were distant suns
Reasons why astronomers have difficulty looking at distant stars except?
Light years of dust lanes obscure the view of distant stars in visible light. However, radio telescopes can penetrate the dust and can detect (in the x-ray and infrared spectra) the stars in the core of our galaxy.They don't understand how redshift affects stars.
What can you deduce from stars that are hot but not very bright?
That they are distant or small
Do nearby stars have larger angles than distant stars have?
Yes, nearby stars generally have larger parallax angles than distant stars. Parallax is the apparent shift in the position of a star when observed from different points in Earth's orbit around the Sun. The closer a star is to Earth, the greater the angle of this shift, making it easier to measure compared to more distant stars, which exhibit much smaller angles due to their greater distances.
What are the methods that astronomers use to identiy the composition of distant stars?
Spectroscopy.
