NGC 6240 harbors three supermassive black holes at its core: the northern black hole (N) is active and was known before; the zoomed-in new high-spatial resolution image shows that the southern component consists of two supermassive black holes (S1 and S2); the green color indicates the distribution of gas ionized by radiation surrounding the black holes; the red lines show the contours of the starlight from the galaxy and the length of the white bar corresponds to 1,000 light years.
