NGC 2419 (Caldwell 25), "Intergalactic Wanderer", Lynx
NGC 2419 is a globular cluster in the constellation of Lynx, discovered by William Herschel on new year's eve 1788. Its heliocentric distance, estimated by the RR Lyrae period-luminosity relation, is 285,000 light years. It lies about 300,000 ly from the Milky Way center, nearly twice as far as the Large Magellanic Cloud and three times the diameter of the Milky Way disk. In the 1920s Harlow Shapley named it the "Intergalactic Wanderer", assuming it to be gravitationally unbound from the Milky Way, drifting in space between us and the Andromeda galaxy. In his detailed 1999 review of globular clusters, Canadian astronomer Bill Harris found that it does indeed orbit the Milky Way, but with an astonishing period of 3 billion years. While it is an easy photographic target, due to extreme distance the cluster presents an unrewarding view in modest telescopes. Its integrated apparent magnitude is 9.06, angular size 6 arcmin, and the brightest stars are only magnitude 17. Actually, the cluster is intrinsically one of the brightest, largest, and most massive in the Galaxy. Its diameter is 500 light years, which is about three times larger than Messier 13 and Omega Centauri. Its mass is estimated at 900,000 solar, compared to 600,000 solar for M13, and 4 million solar for the majestic Omega Centauri cluster. As these numbers indicate, NGC 2419 is substantially less dense than a typical globular cluster. Large telescopes can resolve stars in its core.
Aside from its great distance and size, the cluster is exceptional in another way. Its Red Giant Branch stars include two distinct stellar populations, one ancient, of low metallicity, dispersed peripherally, and the other younger, of higher metallicity, concentrated centrally. Norris 2004 and Piotto et al. 2005 report finding 15 mixed stellar population globular clusters in the examined sample of 114 (13%). Some of these, like Omega Centauri, are remnant cores of dwarf galaxies. Since globular clusters are characteristically composed of stars with nearly identical metallicity and age, the Wanderer was initially presumed to be the remnant core of a merged dwarf galaxy. However, further investigation showed no evidence of an associated stellar stream, stellar kinematics indicated absence of a dark matter halo, and more detailed stellar mass and metallicity studies revealed distributions incompatible with a dwarf spheroidal galaxy core. To date, the formation of this cluster remains hypothetical and unreplicated by computer simulation. A "reasonable" but unproven scenario might involve a slow merger between an older and a younger globular cluster eons ago. Forbes and Bridges 2010 list the age of NGC 2419 as 12.3 billion years. However, mixed stellar population introduces uncertainty in this value.
The annotated image marks several other objects of interest in the surrounding field. Distant galaxy 2MASX J07365472+3851555 (z = 0.12068) is similar to the Milky Way in size and luminosity. It illustrates our significance in the Universe to an observer 1.5 billion light years away. The most distant object is luminous quasar [VV2006] J073740.0+384413 (z = 1.4010). It lies at a light travel distance (lookback time) of 9.1 billion light years, radiating 1,750 times more brightly than our entire Galaxy.

Well Now don't you tell me to smile
You stick around I'll make it worth your while
Got numbers beyond what you can dial
Maybe it's because I'm so versatile
Style profile I said
It always brings me back when I hear Ooh Child
From the Hudson River out to the Nile
I run the marathon til the very last mile
If you battle me I will revile
People always say my style is wild
You've got gall you've got guile
To step to me I'm a rapophile
If you want to battle your in denial
Coming from Uranus to check my style
Go ahead put my rhymes on trial
Cast you off into exile

The Intergalactic Girl always wanted to explore the universe and go on space adventures, but she got stuck guarding a remote outpost on a bare planet. I guess she should have been careful what she wished for because one day the notorious Space Villain and his merciless crew of space pirates came to raid the outpost! Can she fend off the scum together with her astronaut friends?

this is an old picture I took while a friend let me borrow his lens, I decided to go back and make something of it.
hope you Enjoy ! :]
Whilst i started my new job i lived in a small room for 4 months whilst i saved up the money to move my family, and i built this from a small pile of lego i had in my room.
