The big star shoots with 2.4 million kilometers per hour through the halo of the Milky Way. It can't be born there because it is too young. No more new stars are born in the halo. It seems that it comes out of the Large Magellanic Cloud. To this high speed it only could have been accelerated by an enormous huge mass, probably a supermassive black hole like Sagittarius A*. But something like this hasn't been discovered so far in the Large Magellanic Cloud.
The star reminds much of its counterpart which has been outcast of the Milky Way.
