Hubble Team Breaks Cosmic Distance Record        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        NYT        29 May 2014

 

 

 

 

A Galaxy Far, Far Away...Will Hit Ours | 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

vendredi 14 octobre 2005 - 16:05    Libération.fr

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.

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.
