"Infinity" at the Center of the Galaxy

New observations from the Herschel Space Observatory show a bizarre, twisted ring of dense gas at the center of our Milky Way galaxy...Astronomers were shocked by what they saw -- the ring, which is in the plane of our galaxy, looked more like an infinity symbol with two lobes pointing to the side. In fact, they later determined the ring was torqued in the middle, so it only appears to have two lobes.
According to Wikipedia and National Geographic, there is a massive black at the center of our galaxy at Sagittarius A. Yet there is no Sagittarius A or black hole shown in the Herschel observations that I can see. Are there now to be two centers of our galaxy? What happened to the black hole? Lost, stolen, dissolved or never there to begin with? Do other spiral galaxies work like ours does? I suspect that they do.
Respectfully submitted,
Steve
