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."

Data: There's a planet orbiting a metal-poor star.
Conclusion: IT COMES FROM OUTSIDE OUR GALAXY. ....wait what?

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.
