*** TODAY'S PUZZLE ***
Marty Sears does incredible things in sudoku grids. This puzzle, Galaxies Collide (Again!), is one of his finest hours. The number of beautiful logical steps necessary to solve it is exceptional but so is the fact that this grid can possibly exist. How in the galaxy can this have a unique solution? You'll see what we mean if you give it a try.

Rules:
Normal sudoku rules apply. Divide the grid into two galaxies of orthogonally connected cells. No 2x2 area may be completely within one galaxy. Both galaxies must be symmetrical through 180 degrees. A digit in a green circle indicates how many cells in its sudoku box are in its galaxy. A digit in a red square indicates how many cells in its sudoku box are NOT in its galaxy. One of the two galaxies is special. In that galaxy, for any two orthogonally adjacent cells, dividing one digit by the other always gives an exact integer (one is a multiple of the other.)
