If you look really closely (the highest possible resolution) it looks like an Advent ship, its sorta triangular shaped with the wide engine on the back.
On second thoughts, nah, too irregular, two black holes maybe? Other than that I can't think of anything except maybe a binary pair of planets in the distance, a dead star (not a black hole), an asteroid, a Space Station or a hole in the wallpaper.
Really loving that TEC ship though, butt ugly can be beautiful.
