What did hubble conclude when he noted that light emitted from stars is shifting toward the red end of that electromagnetic spectrum?
(A) The universe is expanding.

What did Hubble conclude when he noted that light emitted from stars is shifting toward the red end of the electromagnetic spectrum?
He concluded that the universe is expanding.
What did Hubble conclude when he noted that light emitted from stars is shifting toward the red of the electromagnetic spectrum?
He noted that light emitted from stars is shifted further toward the red of the electromagnetic spectrum . From this he concluded that the universe was expanding.
What did hubble conclude when he noted that light emitted from stars is shifting toward the red end of the electromagnet spectrum?
Hubble, after some time, released that the Red Shift he was seeing meant that these stars were hurtling away from the Earth at a large velocity.
What did Hubble conclude when he noted that light emitted from stars is shutting toward the red end of the electromagnetic spectrum?
The universe is expanding.
What did hubble conclude when he noted that light emitted from star is shifting toward the red end of the electromagnetic spectrum?
The obvious conclusion is that the Universe is expanding - the redshift is interpreted as a Doppler shift, therefore it seems that distant galaxies are moving away from us. This interpretation is widely accepted nowadays; there aren't any other explanations that are generally consistent with observations. I am not sure whether Mr. Hubble concluded that, but I think he did.
What did Edwin hubble discover about the redshift?
Edwin Hubble discovered that galaxies are moving away from us, and the further a galaxy is from us, the faster it is moving away. This phenomenon is known as redshift, where the light emitted from these galaxies is shifted towards the red end of the spectrum due to their motion away from us.
Who developed the red shift method?
Christian Doppler, and Austrian Physcist .
Who first attached a spectroscope to a telescope to study the spectrum of stars?
Hubble
Who stated that the universe is still expanding?
Hubble did not conclude that the Universe is expanding. Hubble thought the red shift indicated a unrecognized principle of nature. Hubble's constant actually shows the universe is bounded at R=150kMpc/31 and H= c/R = 62km/s/Mpc. The increase red shift velocity indicates a decreasing universe.
How can absorption and emission spectra be used by the Hubble space telescope to study the structured of stars or other objects found in deep space?
The light generated by stars is mostly generated by hydrogen fusion. The light emitted from hydrogen has a distinctive emission spectrum. The emission spectrum undergoes shifting when the source and the receiver (Hubble) are moving in relation to each other. The spectrum will shift to the higher frequencies and shorter wavelengths ("blue shift") when the source and receiver are moving towards each other. Due to the "fact" that the universe is expanding, the source and receiver are moving away from each other. This causes the emission spectrum to shift to lower frequencies and longer wavelengths ("red shift"). The amount of red shift is an indication of the rate at which the cource and the receiver are moving away from each other. The expanding of the universe implies that the farther a source is from the receiver, the farther away the source and receiver are from each other. The red shifts of current objects have estimated that the farthest objects that we see are ~10-15 (not sure of exact number) billion light years distant from earth. As for absorption, the light emitted from a star that passes through gases of interspace and of planets will be absorbed at different wavelengths depending on the elements contained within the gas. This allows the determination of planetary atmospheres and intergalactic clouds.
