On this one I have to say it is just a JPEG artifact in the image - the black item is is the exact same size as the JPEG grid. The way image compression works is that in some cases the color of a majority area of pixels within a block becomes the block color. We can see in the image that the blocks are pretty coarse size so the black of space background became the whole block's color.
