There are about a 100 known blue shifted galaxies.

The most well known, is the Andromeda Galaxy.

Do galaxies shift near or far away from earth?

Most galaxies have a red shift away from us - meaning they are moving away from us. However, the Andromeda galaxy has a blue shift, which means it is moving towards us. In about 2.5 billion years time, the two galaxies will merge.


Who discovered blue shift?

The blue shift phenomenon was discovered by the American astronomer Edwin Hubble in the 1920s. He observed that the light from distant galaxies appeared shifted towards the blue end of the spectrum, indicating that these galaxies were moving away from us. This discovery provided crucial evidence for the expansion of the universe.


What could happen if all galaxies experience a blue shift?

It would be an indication that they are moving towards us.


What did hubble discover as a result of studying red shift of distant galaxies?

that the universe was in 1904 expanding. this was due to the lack of blue shift, therefor it can be deduced that the red shift in orrcuring within the galaxy.


What is the Doppler shift of galaxies?

It shows how galaxies are moving in relation to Earth.


What logical conclusion could be made if the light from all of the galaxies were affected by blue shift?

They would all be approaching each other.


Why scientist don't expect to find galaxies that have large blue shift?

This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.


How is the red shift and blue shift related to the big bang theory?

If a galaxy is red-shifted, the distance us and that galaxy is increasing. If it is blue-shifted, the distance is decreasing. If the galaxies in our Universe were random in their velocities relative to us, about half of them would be red-shifted and about half would be blue-shifted; and the distance between us and another galaxy would have no effect on the ratio. But that's not what we see. All galaxies outside our Local Cluster are red-shifted, and we find that the greater the distance between us and a galaxy, the greater the red shift. That the size of the red shift depends on the distance is isotopic in all directions, meaning the distance between us and all other galaxies is increasing at the same ratio based on distance from us. The BEST explanation of this undeniable fact is that, at some time, space itself (NOT the matter, but space) began to expand, taking matter along for the "ride." IF that hypothesis is correct, we would observe, not only red-shift in all distant galaxies, but other effects. We do indeed see the latter, and exactly as predicted by the Big Bang.


What did hubble discover as a result of studying the red shift of distant galaxies?

Hubble discovered that the redshift of distant galaxies indicated that the universe is expanding, which provided evidence for the Big Bang theory. This observation also led to the realization that galaxies are moving away from each other, with those farther away moving faster, suggesting an overall expansion of the universe.


Why hypsochromic shift is known as blue shift but not violet shift?

hypsochromic (blue) shift


Does red shift have anything to do with irregular galaxies?

NoRed shift is the Doppler effect as it applies to the light from receding galaxies and stars.As the name suggests, "irregular" galaxies have no specific form, and so the group contains a very diverse selection of objects.


What is red shift inti?

When galaxies move away from us, the waves of light stretch out- ie, they become redder. The greater the red shift, the faster the galaxies are moving away from us.
