Hubble Team Breaks Cosmic Distance Record Video NASA 3 March 2016
This animation shows the location of galaxy GN-z11, which is the farthest galaxy ever seen.
The video begins by locating the Big Dipper, then showing the constellation Ursa Major.
It then zooms into the GOODS North field of galaxies, and ends with a Hubble image of the young galaxy.
GN-z11 is shown as it existed 13.4 billion years in the past, just 400 million years after the big bang, when the universe was only three percent of its present age.

A Galaxy Far, Far Away...Will Hit Ours Video Out There | The New York Times 29 May 2014
Recently, Hubble Space Telescope measurements have confirmed that the Milky Way will collide with a sibling galaxy known as the Andromeda nebula in about two billion years.

Barred Spiral Galaxy NGC 6217
This image of barred spiral galaxy NGC 6217 is the first image of a celestial object taken with the newly repaired Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope.
The camera was restored to operation during the STS-125 servicing mission in May to upgrade Hubble.
The barred spiral galaxy NGC 6217 was photographed on June 13 and July 8, 2009, as part of the initial testing and calibration of Hubble's ACS.
The galaxy lies 6 million light-years away in the north circumpolar constellation Ursa Major.

Andromède, panier percé
Des étoiles lumineuses et vieillissantes et un arc en spirale au centre de la galaxie, c'est Andromède vue avec les yeux infra-rouges de Spitzer, un télescope spatial de la Nasa dont les images ont été montrées jeudi.
La plus étudiée des galaxies laisse apercevoir plusieurs éléments jamais observés.
Sur la vue obtenue par Spitzer, l'anneau d'Andromède semble coupé en deux morceaux –en haut à gauche et en bas à droite.
Ces entailles asymétriques ont pu être provoquées par des interactions avec les galaxies voisines.
«Parfois, des petites galaxies satellites peuvent pénétrer dans des plus grandes», explique Karl Gordon (Université d'Arizona, Tucson), responsable de l'observation. en bas à droite, «une petite galaxie a percé un trou dans le disque d'Andromède, comme un caillou perce la surface d'un étang.»
En outre, on peut voir dans la moitié gauche de la galaxie un anneau d'étoiles en formation.
Située approximativement à 2,5 millions d'années-lumière, Andromède est la galaxie en spirale la plus proche, et la seule visible à l'œil nu.
À la différence de la Voie Lactée, que nous regardons de l'intérieur, Andromède est étudiée de l'extérieur. http://www.libe.com/page.php?Article=313053&Template=GALERIE&Objet=47659 © REUTERS/NASA/JPL-Caltech/Univ. of Arizona

1 light year is the distance light can travel in vacuum in one year’s time.
This distance is equivalent to roughly 9,461,000,000,000 km or 5,878,000,000,000 miles.
This is such a large distance.
For comparison, consider the circumference of the Earth when measured at the equator: 40,075 km.
You can even throw in the center to center distance between the Earth and the Moon, 384,403 km, and that value would still pale in comparison to 1 light year.
Pluto, at its farthest orbit distance from the Sun, is only about 7,400,000,000 km from the center of our Solar System.
Because of its great scale, the light year is one of the units of distance used for astronomical objects.
For example, Andromeda Galaxy, which is the nearest spiral galaxy from the Milky Way, is approximately 2.5 million light years away.
Alpha Centauri, the nearest star system from our own Solar System is only 4.37 light years away. http://www.universetoday.com/39725/1-light-year/

early universe / primordial cosmos > giant rotating disk galaxy Wolfe Disk / ALMA J081740.86+135138.2 USA
On Wednesday, radio astronomers using the mighty Atacama Large Millimeter Array, or ALMA, radio telescope in Chile announced that they had discovered a cloud of gas located on the distant shores of time.
It appears to be an infant galaxy similar in size to its grown-up counterpart, our own Milky Way, and dates to a time when the universe was only 1.5 billion years old, one-tenth its current age.
The galaxy, known formally as ALMA J081740.86+135138.2, after its coordinates in the sky, is a giant, rotating wheel of gas, dust and faint starlight — a so-called disk galaxy — that extends 100,000 light-years across the primordial sky.
It is at least as massive as 70 or 80 billion suns, in the same weight class as the Milky Way.

on the outer edge of the Milky Way
on the fringes of the Milky Way
South Pole Wall
The South Pole Wall, as it is known, consists of thousands of galaxies — beehives of trillions of stars and dark worlds, as well as dust and gas — aligned in a curtain arcing across at least 700 million light-years of space.
It winds behind the dust, gas and stars of our own galaxy, the Milky Way, from the constellation Perseus in the Northern Hemisphere to the constellation Apus in the far south.
It is so massive that it perturbs the local expansion of the universe.
But don’t bother trying to see it.
The entire conglomeration is behind the Milky Way, in what astronomers quaintly call the zone of avoidance.
