Milky Way

 

Dragon’s lair – Daniel Thomas Gum | Mungo, NSW, Australia
 

‘This is my favourite nightscape image to date.

Mungo is a 12-hour drive away from my home in Sydney,

but those Bortle 1 skies

are the best I’ve ever witnessed and photographed at night.

I had perfect conditions for three straight nights,

with really good seeing throughout.

 

The moment I came upon this scene,

I knew exactly what I wanted to the name the image.

It was otherworldly – think Game of Thrones –

and it lined up perfectly for how I wanted to capture it.

Large, jagged walls framed a winding path

leading to a centred spire to the west.

 

There was only ever going to be one way to do it justice

and that was as a multi-layered Milky Way panorama.

I planned this image using PhotoPills during the day,

but in post-processing,

I decided to use the blue-hour blend for the foreground

with a tracked sky for the cleanest possible image’

Milky Way photographer of the year 2021 – in pictures

The annual Milky Way photographer of the year competition

features the best photos of our galaxy as selected by Capture the Atlas.

This year’s images were taken from around the world

by 25 photographers of 14 different nationalities.

The best time to see and photograph the Milky Way

is usually between May and June

with maximum hours of visibility on both hemispheres

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.

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.

2261 galaxy > cluster > Abell 2261 > black hole        USA

 

It is about 2.7 billion light-years from here,

in the constellation Hercules in the northern sky,

not far from the prominent star Vega.

 

Using the standard rule of thumb,

the black hole missing

from the center of the 2261 galaxy

should be 10 billion solar masses or more,

comparable to the mightiest

of these monsters known to astronomers.

 

The black hole

at the center of the Milky Way galaxy

is only about four million solar masses.

 

So where has nature stashed

the equivalent of 10 billion suns?

 

One possibility is

that the black hole is there but has gone silent,

having temporarily run out of anything to eat.

 

But another provocative possibility,

Dr. Lauer and his colleagues say,

is that the black hole was thrown

out of the galaxy altogether.

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.

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.
