First Alien Planet From Another Galaxy Discovered

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. A side effect of the galactic cannibalism brought a faraway planet within astronomers' reach for the first time ever.

This video sums up what the fuss is about:

To further sum it up:

-There is a disturbance to a star which the astronomers from the Max-Planck institute believe to be caused by a planet.

-The star is old, has very little metal. Some models indicate that those stars can or cannot have planets aggregating around them. Yet it is concluded that this planet must not be native of this star.

-If the planet is not "native", then it can come from another galaxy that collided with ours.

Looks like weak evidence to support such a bold claim. I cannot find info on why they are so damn sure that this planet isn't just from another solar system within our galaxy. Maybe someone can enlighten me.

I'm just curious and am in no way an astronomer....How the hell do they know this star and planet were from another galaxy? Does this star have something that all the other stars in our galaxy don't have?

Anyways, this is very interesting because they have found an alien-alien planet. And whose to say it has not traveled before that.?. Just think of the possibility of multi-galaxy alien life forms being contained in such planet.

I'm also wondering how they can distinguish which planets are from this galaxy and which are not. Could not find an answer so far.

im sure they know by examining the area it is located on and any debris and what not that could be trailing from the other galaxy. it could be on an arm of the milky ways spiral that could be dated back to have collided with the other galaxy? just a couple theories tho

Are you trying to say that we are living in a galaxy which seems to have - humm - planeto-phage habits ?

"On Earth, as it is in Heavens"
Far from my mind any intention of invoking something or someone able to give you a short but precise answer...

Apparently the whole region the planet was found in, was a dwarf-galaxy the milky way swallowed up long ago. that sort of destroys the sensation

It actually follows the recent discovery that our solar system was not origionally native to the milky way galaxy. Science has developed a new theory that our solar system was absorbed by the milkyway galaxy. The theory holds that we were part of a much smaller galaxy that collided with the milky way, which was a lot more massive.

This theory came out towards the first part of this year if I remember right.

Quick link to the basics of this theory

Using volumes of data from the Two-Micron All Sky Survey (2MASS), a major project to survey the sky in infrared light led by the University of Massachusetts, the astronomers are answering questions that have baffled scientists for decades and proving that our own Milky Way is consuming one of its neighbors in a dramatic display of ongoing galactic cannibalism. The study published in the Astrophysical Journal, is the first to map the full extent of the Sagittarius galaxy and show in visually vivid detail how its debris wraps around and passes through our Milky Way. Sagittarius is 10,000 times smaller in mass than the Milky Way, so it is getting stretched out, torn apart and gobbled up by the bigger Milky Way.

So they do hvae some sound ground to advance the theory of the planet imo.

That's cool. This would also make it possible for microbial life to spread from one galaxy to another

we are all made of the same stuff.

a billion light years away doesn't mean the laws we know would be different.

we wouldn't know anyway, if they were.

it is rumored, we were from another galaxy that collided with the milky way long time ago, too.
