What do you think about it?
There is so much stars in our galaxy but such event is only now registered, a star leaving galaxy...
This may sound a little crazy, but here it goes:
i have an idea(not really serious) that this could be a alien spaceship for whole its civlisation to leave this galaxy for some reason..for example a gamma ray brust?
Any other ideas ?
JUst willing to chat about it...

Well, if it were a spacecraft, and someone knew something about it, they'd likely keep us in the dark, no? -_-
