Astronomers have confirmed the first discovery of an alien planet in our Milky Way that came from another galaxy, they announced today (Nov. 18).
The Jupiter-like planet orbits a star that was born in another galaxy and later captured by our own Milky Way sometime between 6 billion and 9 billion years ago, researchers said.

"This is very exciting," said study co-author Rainer Klement of the Max-Planck-Institut fur Astronomie (MPIA) in Heidelberg, Germany. "We have no ability to directly observe stars in foreign galaxies for planets and confirm them."
Stars currently residing in other galaxies are simply too far away, Klement added.
The find may also force astronomers to rethink their ideas about planet formation and survival, researchers said, since it's the first planet ever discovered to be circling a star that is both very old and extremely metal-poor. Metal-poor stars are lacking in elements heavier than hydrogen and helium.
The newfound planet, called HIP 13044b, survived through its star's red-giant phase, which our own sun will enter in about 5 billion years. So studying it could offer clues about the fate of our solar system as well, researchers said.
HIP 13044b sits extremely close to its parent star, which has now contracted again. The planet completes an orbit every 16.2 days, and it comes within about 5 million miles (8 million kilometers) of its parent star at closest approach just 5.5 percent of the distance between Earth and the sun.

Are there Liberals on it?
Have they done the DNA for proof?
There is Astronomical spectroscopy
“First alien planet”? - California!
the milky way stole a planet?
Rogue planets are ejected and are captured by galaxies and solar systems
"My God, they're everywhere!"
Classic. I'll be laughing about that one the rest of the night.
Naw, it came over looking for a star, er job, er came over looking to be a spiral member instead of a cluster blob.
Now you know why our galaxy is moving so fast through the Universe.
Trying to outrun the cops.
Home of Sheila Jackson-Lee?
Say, can I borrow that for a pickup line to use at the bar?
Great. Now Harry Reid can drop the DREAM Act. They have their own planet.
All those stars, it would be awfully weird if there were no other planets like ours out there. It’d be both proof of God and a limited imagination on His part! ;)
Illegal immigrant planet?
Doh! Guess I should read beyond the first sentence. I’m an idiot.
