What are the spectral lines of starlight from distant galaxies?
They are the characteristic frequencies of the elements "burning up" in the stars in the galaxy interspersed with absorption lines of other material between these elements and the earth. All these wavelengths will be increased by the red shift which results from the galaxy receding from the earth.
According to Hubble's Law the most distant clusters of galaxies are?
The basic idea of Hubble's Law is that galaxies (or galaxy clusters) that are farther away move away from us faster than those that are closer to us.The most distant galaxy yet found is a protogalaxy with the designation UDFj-39546284, with a redshift z = 11.9, about 13.42 billion light-years distant from the Milky Way.In case you are asking for the most distant CLUSTER of galaxies, and not the most distant astronomical galaxy, the answer would be the cluster (or protocluster, science is not yet sure about the nature of this structure) which denomination is BoRG-58 , with a redshift z≅8, and about 12 billion light-years distant from us.
Do distant galaxies have more heavy elements than nearby galaxies?
The distribution of metals (In astronomy, that is any element other that hydrogen and helium) is reliant of the population stars. (See related question) Metal rich stars, population I stars, are the latest "breed" of stars, whereas population III stars are the oldest and are classed as metal free stars. So the furthest galaxies are likely to be formed from the initial gases from the big bang and will be metal free stars,
How does redshift support the notion of the expanding universe?
The redshift of distant galaxies is believed to be a result of the Doppler effect - in other words, the light is shifted towards lower frequencies ("redshifted") due to the fact that the galaxies move away from us.
Do action-at-a-distance forces require physical contact between objects?
No. A couple of examples:- . The Cosmic Microwave background, is the residual radiation signature left over from the time of the creation of the Universe from the Big Bang. . The determination, by means of a spectroscope, of the spectral lines indicating the presence of particular elements in a distant star. . You may argue that the traffic microwave radar has its waves impinging on the target vehicle, but most would consider this a non-contact measurement.
Based on the observed red shifts in the spectral lines of distant galaxies?
Astronomers conclude that the universe is expanding, because wavelengths are increasing.
The spectral lines from distant galaxies do not match spectral lines on Earth due to?
wavelength shift

The visible part of distant galaxies is the galaxies'?
Stars
The visible part of distant galaxies is the galaxies what?
The "nucleus".
How the presence of certain element is confirmed in distant stars?
spectral analysis of light of stars help us
Why do scientists study distant galaxies to learn about galaxies?
cuz they are explorers
What have astronomers seen beyond your galaxy?
We have observed distant galaxies. The furthest object so far observed is a small galaxy that has been dated to be about 13 billion years old. About 750 million years after the big bang.
Why do scientist study the light coming from distant galaxies?
They study distant galaxies because they want to know whats out in other galaxies and how many planets it has
Quasars are thought to be the center of distant?
galaxies
The fact that the light from distant galaxies is red-shifted suggests that the galaxies are?
Moving away from us
How do the distant galaxies ussually move?
Away from us.
