What Is the Weird Black Cube on the Sun in This New NASA Image?

A nit pick, I guess, but it’s a square, not a cube.

The edges are interesting. I wonder what part of the image processing results in the irregularity. Some kind of interpolation, I’d guess, but that’s pure speculation.

I don't think the edges are all that interesting. The stair-stepped appearance is just what you inevitably get when you rotate a square in low resolution without antialiasing.

Now that you point it out, that seems to be the case. The fuzziness around the edges (the east and north especially) threw me off, though that could probably be put down to compression in the image that was used as the source for the crop.
