If we presume that our Galaxy is spinning horizontally, then the center of our galaxy is rotating at right angles to the galactic plane. How can we tell? If the center would rotate on the same plane as the galaxy itself, we would only be able to see the center as a narrow band, the same way we see our Milky Way. But since we can see this special form, shaped like a mini-galaxy, we have to assume that its rotational plane must be slanted by about 90 degrees. And there is even more to it: just by chance the center is positioned in a way that it reveals its Om-shape to us and its northpole is directed towards our solar system. How do we know that it is the northpole? The shape of the center tells us which direction it is spinning and it is spinning counterclockwise.

Here we can see the stars/suns that are closest to the galactic center, marked by a cross, depicted in four phases.
