Extra-Galactic Planet Discovered In Milky Way
astroengine writes "Between six to nine billion years ago, the Milky Way collided with another galaxy. As you'd expect, this caused quite a mess; stars, dust and gas being ripped from the intergalactic interloper. In fact, to this day, the dust hasn't quite settled and astronomers have spotted an odd-looking exoplanet orbiting a metal-poor star 2,000 light-years from Earth. Through a careful process of elimination, the extrasolar planet (known as HIP 13044b) actually works out to be an extragalactic planet, a surviving relic of the massive collision eons ago."

six thousand years old of-course.
Fornax was identified by Nicolas Louis de Lacaille in 1756. He originally called it Fornax Chemica ("chemical furnace"), representing a small solid fuel heater used for heating chemical experiments.
There are 40 unknown "dwarf" galaxies in this constellation and has ultra compact dwarfs are much smaller than previously known dwarf galaxies, about 120 light-years across
NGC 1316 is a notably bright elliptical galaxy within the Fornax Cluster. The galaxy is also one of the brightest radio sources in the sky.
UDFy-38135539, a galaxy which was identified as the most distant object in the universe from Earth as of October 2010, is located in Fornax. It was detected using the Hubble UDF image.

They actually address that hypothesis:
Finally, as a member of the Helmi stream, HIP 13044 most
probably has an extragalactic origin. This implies that its
history is likely different from those of the majority of known
planet-hosting stars. HIP 13044 was probably attracted to the
Milky Way several Ga ago. Before that, it could have had
belonged to a satellite galaxy of the Milky Way similar to
Fornax or the Sagittarius dwarf spheroidal galaxy (14).
Because of the long galactic relaxation timescale, it is
extremely unlikely that HIP 13044 b joined its host star
through exchange with some Milky Way star, after the former
had been tidally stripped. The planet HIP 13044 b could thus
have a non-Galactic origin.
No kidding!!! What do you say at this point?
The star is part of a group widely accepted to have an extragalactic origin due to their orbit.
No kidding!!! What do you say at this point?
When I first read the headlines elsewhere, I wondered how we could have advanced sensitivity by a few orders of magnitude to distinguish individual stars in another galaxy, nevermind planets. Slashdot's headline is nonsensical. I find it kind of hard to think of a star that's "in the Milky Way galaxy" as being extragalactic. I'll even trust that the astronomers' science is right on: they're able to detect if a star matches indicators for originating in this galaxy or that galaxy. Maybe it used to be a part of a different galaxy pre-collision, but I would say it's in this galaxy now, so it's not an extragalactic star system. This article itself occasionally uses the phrase "of extragalactic origin" and I'm okay with that, but simplifying it further actually makes it more confusing.

Data: There's a planet orbiting a metal-poor star. ....wait what?
Conclusion: IT COMES FROM OUTSIDE OUR GALAXY.
Datum 1: The star comes from the Helmi Stream, a well understood remnant of a dwarf galaxy consumed by our own.
Datum 2: You've been modded insightful.
Conclusion 1: Neither you, nor the mod, read TFA.
Datum 3: TFA doesn't even mention this.
Conclusion 2: I hadn't read TFA either.
Recommendation: Read http://blogs.discovermagazine.com/badastronomy/2010/11/18/exoplanet-found-from-another-galaxy/#more-24148 for a much better explanation.

"Hip 13044b" is a waste of a perfectly good excuse to name it Eddore.
OK, so its extra-galactic rather than extra-dimensional, but that's the closest we're likely to get, and Doc Smith had colliding galaxies, too.

From wikipedia:
In 2007, a star in the Galactic halo, HE 1523-0901, was estimated to be about 13.2 billion years old, nearly as old as the Universe. As the oldest known object in the Milky Way at that time, it placed a lower limit on the age of the Milky Way

Why don't we just call it an "immigrant" star, then? Since this is the first time we're hearing of it, and it's billions of years old, it's probably here illegally^W^W undocumented. I suggest we give it full social security and Medicaid entitlements, plus in-galaxy tuition at the college of its choice.

Wrong! God creates the stars after creating the Earth (the latter is created in the Third Day, while the former are only created in the Fourth), and since a galaxy by definition includes stars, it must be six thousands years old or younger.

The Bible makes no claims as to the age of the galaxy, only the age of the earth.
Actually, it's worse than that. The bible makes no claims about the age of the earth either, it simply says that in the beginning, whenever "the beginning" was, God created it. 6000 years comes by counting the ages listed from Adam down through his descendants. The problem with using this as the age of the earth, or anything listed as created before Adam for that point, is two-fold.
First of all, if Adam was immortal before sinning, then he also did not age before sinning, and therefor one can not infer from the text if his listed age is from the moment of his creation, or from the moment he became mortal. With this in mind he could have been 10 million years old when he sinned and became mortal, thus starting the aging process.
Second of all, There is no record of time before Adam was created. Sure, the Bible records everything that is as being created in 6 "days", but it also uses the word "day" arguably before the Sun is listed as being created, assuming the Sun was created not on "day" 1 when he said let there be light, but on "day" 4 when he created the lights in the heavens. Does "day" mean 24 hours? Or is it an arbitrary separation of an unknown amount of time? And regardless of the answer to that question, if a day is a cycle of light and darkness and/or 24 hours and/or whatever, light didn't exist until verse 3 of the first chapter. There is no record or indication of how much "time" occurred prior to verse 2, if "time" even means anything in that context.
Furthermore, there is no evidence that supports that any of that means light in general was created for the first time in verse 3, or simply light visible to the mass of ocean called "earth".
In a nutshell, if you (and by you I mean anyone, not AC parent) want to try to pick apart the historical accuracy of the bible, you should try to pick apart Exodus, or perhaps Kings/Chronicles. Mid Genesis at the latest. The account of creation is rather vague with time periods and meanings. Some people believe that millions if not billions of years of men and dinosaurs and all kinds of nifty things happened between the first and second half of genesis 1:1.
Now, you're all experts in astronomical nomenclature? Have any of you even heard the term "extragalactic" before this article? People are whining like the planet has to come screaming out of the void from the edge of the universe to be "extragalactic". You don't like the definition, get your PhD in astrophysics and make up a new one.
I swear to God...I swear to God! That is NOT how you treat your human!
The Bible makes no claims as to the age of the galaxy, only the age of the earth.
In the beginning God created the heavens and the earth. First line of genesis from whichever version of the bible google pulled up for me.
Seems to me that quantifying decayed isotopes in rocks is actually more straightforward. With the added bonus of giving THE CORRECT ANSWER.
The bible states a direct male lineage with names and ages from Adam (at Creation) to King Solomon. From there, it names kings and the lengths of their reigns. After that, events in the bible can be corroborated with records of other cultures, such as the death of the Chaldean King Nebuchadnezzar.
Besides, the GP said six thousand, not sixteen thousand.

How... virile of us.
If more astronomers were women, I expect we'd talk about enfolding another galaxy and gently persuading a planet to move in with us.

Yeah, Earth before stars; AINULINDALË and VALAQUENTA.
There was Eru, the One, who in Arda is called Ilúvatar; and he made first the Ainur, the Holy Ones, that were the offspring of his thought, and they were with him before aught else was made. And he spoke to them, propounding to them themes of music; and they sang before him, and he was glad.
Then Ilúvatar said to them: 'Of the theme that I have declared to you, I will now that ye make in harmony together a Great Music. And since I have kindled you with the Flame Imperishable, ye shall show forth your powers in adorning this theme, each with his own thoughts and devices, if he will. But I win sit and hearken, and be glad that through you great beauty has been wakened into song.'
But when they were come into the Void, Ilúvatar said to them: 'Behold your Music!' And he showed to them a vision, giving to them sight where before was only hearing; arid they saw a new World made visible before them, and it was globed amid the Void, and it was sustained therein, but was not of it.
Ilúvatar called to them, and said: 'I know the desire of your minds that what ye have seen should verily be, not only in your thought, but even as ye yourselves are, and yet other. Therefore I say: Eä! Let these things Be! And I will send forth into the Void the Flame Imperishable, and it shall be at the heart of the World, and the World shall Be; and those of you that will may go down into it. And suddenly the Ainur saw afar off a light, as it were a cloud with a living heart of flame; and they knew that this was no vision only, but that Ilúvatar had made a new thing: Eä, the World that Is.
There was need of light, [and] Aulë at the prayer of Yavanna wrought two mighty lamps for the lighting of the Middle-earth which he had built amid the encircling seas. Then Varda filled the lamps and Manwë hallowed them, and the Valar set them upon high pillars, more lofty far than are any mountains of the later days. One lamp they raised near to the north of Middle-earth, and it was named Illuin; and the other was raised in the south, and it was named Ormal; and the light of the Lamps of the Valar flowed out over the Earth, so that all was lit as it were in a changeless day.
But Melkor, trusting in the strength of Utumno and the might of his servants, came forth suddenly to war, and struck the first blow, ere the Valar were prepared; and he assailed the lights of Illuin and Ormal, and cast down their pillars and broke their lamps.
But as the ages drew on to the hour appointed by Ilúvatar for the coming of the Firstborn, Middle-earth lay in a twilight beneath the stars that Varda had wrought in the ages forgotten of her labours in Eä.
Then Varda went forth from the council, and she looked out from the height of Taniquetil, and beheld the darkness of Middle-earth beneath the innumerable stars, faint and far. Then she began a great labour, greatest of all the works of the Valar since their coming into Arda. She took the silver dews from the vats of Telperion, and therewith she made new stars and brighter against the coming of the Firstborn.

You must not many fundies then. The words in the bible means exactly what they say, except for jesus turning water to wine. There the fundies claim the wine means fruit juice.
Those who believe that each day in genesis is a 24 hour period are a minority. Those who believe that such literalists are the typical christian are either misinformed or practicing their own religion-like article of faith.
Even in literalist churches not all members agree. I've known people who have attended pretty fundamentalist churches and they had no problem with the universe being many billions of years old, the speed of light, radioactive half-life, etc.
Keep in mind that the folks you see on TV are not there because they represent the typical, they are usually there because they represent the most entertaining, or if you prefer the cynical because they represent the stereotype the producer wishes to portray.
