Planets not from our galaxy

I knew our galaxy took in another, but after reading this article, a light came on and it was very interesting to read this. Not only did we have our native aliens in our galaxy, but we devoured another galaxy, thus bringing in their aliens. That might explain the curiosity of some aliens (the new ones) and protection from the native aliens.

To me it makes a lot of sense.

Could this be Planet X? Seems like a possibility to me.
