What kind of Doppler shift did Hubble observe in these distant galaxies?
Most galaxies exhibit a redshift, meaning that they move away from us.
When viewed from earth the light from very distant galaxies shows a red shift evidence that these distant galaxies moving towards or away from earth?
The "redshift" refers to the fact that the light is less energetic than when it was emitted; it shows that the galaxies move away from us. Should a galaxy move towards us - which is possible only for galaxies that are relatively close to us - then there would be a blueshift.
The visible part of distant galaxies is the galaxies'?
Stars
The visible part of distant galaxies is the galaxies what?
The "nucleus".
Why do scientists study distant galaxies to learn about galaxies?
cuz they are explorers
Why was the big bang theory?
The Big Bang theory was set up to explain observations - for example, the redshift of distant galaxies, which is usually interpreted to mean that the galaxies move away from us.
Why do observations made of distant galaxies indicate that dark energy exists?
The observations made from distant galaxies suggest that Dark energy exists. This is because of the fact that the galaxies are moving away from each other. This is given by Hubbles law.Instead of being attracted by the force of gravitation,galaxies tends to move away suggesting the presence of a gravity opposing force called dark energy.
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
Why is spring one of the best seasons to observe distant galaxies?
Because in the spring, the night sky is pointed out of the Milky Way and therefore it is easier to see distant galaxies.
Does light does not require matter to move through?
It doesn't. Light comes to us from the Sun, and from distant stars and galaxies, through what is basically empty space.
