While the Milky Way is a relatively flat galaxy, others are different. Some like Ellipticals can look like a football. Hoag’s Object, however, operates differently. It has an old yellow core, surrounded by a beautiful ring of blue stars. However, there is nothing in the middle as if someone took a bite out of the middle of the thing! Yet another look makes it seems like some sort of space donut!
The “Object” was spotted in 1950 by Arthur Hoag, its namesake. We have yet to see another galaxy of any kind that looks similar. Scientists have no conclusive reasoning as to how this formed. However, the theory is that a small galaxy came through and went right through it. This isn’t a bad theory, as the area spins very slowly, and a small version of the galaxy is hidden in itself.
