Why scientist don't expect to find galaxies that have large blue shifts?
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 did Edwin Hubble determine that the Great Galaxy in Andromeda is located beyond our galaxy?
That became clear once the telescopes were powerful enough to distinguish individual stars in the galaxies. Before that, they were seen only as "nebulae" (cloud-like objects), and it wasn't clear whether M31 (for example) was part of our own galaxy. M31 is also known as the Andromeda Galaxy.
What did Edwin Hubble due to help prove the Big Bang Theory?
Edwin Hubble played a crucial role in providing evidence for the Big Bang Theory by observing the redshift of galaxies. He discovered that galaxies were moving away from each other, and the farther away they were, the faster they were moving. Hubble's observations supported the idea that the universe is expanding, which is a key component of the Big Bang Theory.
How did Edwin hubble sub-categorize spiral galaxies?
Hubble devised subcategorization for spiral galaxies first based on whether the galaxy exhibited a bar and then how well the spiral arms were defined. The classes are designated as Sa, Sb, and SC with the Sa class being the most tightly wound. A capital B designation after the S indicates the presence of a bar as well.
What do the lines in the spectra of most galaxies shifted toward the red end of the spectrum show?
The strongest consensus (nearunanimous of the astronomical community is that the redshifts of distant galaxies indicate that all distant galaxies arerecedingfrom us. This recession is currently the only known mechanism for redshifting light. Take this inference, that all galaxies arereceding and you are led to the idea that the universe is expanding, a phenomena described by Hubble's Law. This is a central tenet to the Big Bang Theory.I will include the counterpoint originally described below, but I will point out that the papers cited are very old, and a huge number of corroborating observations and predictions of the big bang haveoccurredsince then.The conclusion that the Universe is expanding is a wrong conclusion. Alan Sandage talks about Hubble's position at the related link below.To the very end of his writings he maintained this position, favouring (or at the very least keeping open) the model where no true expansion exists, and therefore that the redshift "represents a hitherto unrecognized principle of nature". This viewpoint is emphasized (a) in The Realm of the Nebulae, (b) in his reply (Hubble 1937a) to the criticisms of the 1936 papers by Eddington and by McVittie, and (c) in his 1937 Rhodes Lectures published as The Observational Approach to Cosmology (Hubble 1937b). It also persists in his last published scientific paper which is an account of his Darwin Lecture (Hubble 1953).
What kind of Doppler shift did Hubble observe in these distant galaxies?
Most galaxies exhibit a redshift, meaning that they move away from us.
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.
Who first propsed that the universe is expanding?
The astronomer Edwin Hubble was the first to find evidence of the expansion of the Universe, through his observations of distant galaxies. He observed that light emitted from most of the distant galaxies was more red in color. This is known as the Doppler effect or Doppler shift, where objects that emit a certain wavelength and move away from the observer appear to have a longer wavelength than the true wavelengths to the observer. It's the opposite case when objects emitting waves that are coming closer to the observer. These observations lead Hubble to believe that these surrounding red-shifted galaxies are moving away from us. Since most of the galaxies were moving away from us, and since Hubble found that with increasing distance between the galaxies there is an increasing speed at which they are moving apart, he concluded that the Universe was and still is expanding.
What observation did Edwin hubble make about the movement of galaxies?
In the late 1920s, the astronomer Edwin Hubble discovered that most of the galaxies he observed were moving away from Earth.
What important observation did Edwin Hubble make about the movement of galaxies?
In the late 1920s, the astronomer Edwin Hubble discovered that most of the galaxies he observed were moving away from Earth.
What is the most distant galaxy the Hubble can detect?
The furthest Hubble as ever gazed into the universe is the Hubble Ultra Deep Field. Search that in google and check it out.
How far away are the most distant galaxies?
That is impossible to answer because scientist don't know ALL the galaxies.

What did astronomers Edwin Hubble discover that led to the formulation of his law?
Basically, his discovery was that most galaxies move away from us; and that the galaxies that are farther away, also tend to move away faster.
What imporatant observation did Edwin Hubble make about the movement of galaxys'?
That most galaxies move away from us; and that the general tendency is that galaxies that are farther away move away from us faster.
A distant galaxy with a black hole in its center?
Most galaxies, including our own, have black holes in their centers.
