Astronomers have discovered an object in space that might be a black hole catapulted out of a galaxy. Or, according to an alternative interpretation, it might be a giant star that is exploding over an exceptionally long period of several decades. In any case, one thing is certain: This mysterious object is something quite unique, a source of fascination for physicists the world over because of its potential to provide experimental confirmation of the much-discussed gravitational waves predicted by Albert Einstein.
