it is a eclips, not sure if it is lunar or sun eclips, but in the eclips we will see the circle in the middle.

the outter circle is the sun thats the one on the right side, the darker image inside is earth, the outter one on the left has the little circle in the middle with the 6 links or you can say leaves in it. i think it is refering to a metorite or maybe comet with 6 small legs/leaves indicating its tail or maybe its indicating it will split this earth into and all.

no i did not just think this up or make this info up. it came to my mind as a vision of what i see in this circle. its not man made that i know of but this is what its indicating to me.
