∙ 11y agoHCM-6A is a galaxy that was found in 2002 by a team led by Esther Hu from the University of Hawaii, using the Keck II Telescope in Hawaii. HCM-6A is located behind the Abell 370 galactic cluster, near M77 in the constellation Cetus, which enabled the astronomers to use Abell 370 as a gravitational lens to get a clearer image of the object.
HCM-6A was the farthest object known at the time of its discovery. It exceeded SSA22−HCM1 (z=5.74) as the most distant normal galaxy known, and quasar SDSSp J103027.10+052455.0 (z=6.28) as the most distant object known. In 2003, SDF J132418.3+271455 (z=6.578) was discovered, and took over the title of most remote object known, most remote galaxy known, and most remote normal galaxy known.

∙ 12y agoWe might call galaxies moving away from earth retreating galaxies. Almost all galaxies move away from Earth, or more properly, from the Milky Way, our home galaxy.

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.
Both would probably move away from each other, because the earth moves too.
In the late 1920s, the astronomer Edwin Hubble discovered that most of the galaxies he observed were moving away from Earth.
Edwin Hubble proved that there are other galaxies spread throughout the universe, and that these galaxies move away from each other as the universe expands. He further found that the galaxies in the outermost areas of the universe move faster that those nearer the middle, a feature in his Hubble's Law.
The person who discovered the existence of galaxies outside of the milky way was Edwin Hubble. He also discovered that galaxies move away from each other with a constant acceleration, leading to the big bang theory.
Away.
That has nothing to do with the "type"; it is how far they are away from Earth. Due to the general expansion of the Universe, galaxies that are far way from us systematically move away from us - the farther away, the faster. It is only nearby galaxies which may happen to move towards us.
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.
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.
Some nearby galaxies move towards us (blueshift), some move away from us (redshift). Galaxies that are farther away all move away from us (redshift); this means that the Universe is expanding.
That most galaxies move away from us; and that the general tendency is that galaxies that are farther away move away from us faster.
Away from us.
Galaxies generally move away from one another.
Most move away from us, and each other.
Most galaxies move away from us - the farther they are from us, the faster they move away from us. This means that the Universe is expanding.
Yes !
The general tendency is for galaxies to move away from each other, in other words, the Universe is expanding. Only in our "immediate neighborhood" will you also find some galaxies that move towards us.
