The coordinate grid in the equatorial plane of the spiraling flow shows how strong lensing around the black hole bends the back of the apparent disk up. The left side of the image is brighter due its rotational motion towards the observer. The bright arcs are generated by gravitational lensing. A dark silhouette appears around the location of the black hole because the light emitted by gas behind it disappears into the horizon and cannot be seen by an observer on the other side. Recently, the technology for observing such an image from the supermassive black holes at the centers of the Milky Way and M87 galaxies has been demonstrated as feasible [Doeleman, S., et al. {\it Nature} {\bf 455}, 78 (2008)]. To obtain the required resolution of tens of micro-arcseconds, signals are being correlated over an array (interferometer) of observatories operating at a millimeter wavelength across the Earth.

The image shows a snapshot of the gas density distribution 500 million years after the Big Bang, indicating the formation of two compact objects near the center of the galaxy with masses of $2.2\times 10^{6}M_{\odot }$ and $3.1\times 10^{6}M_{\odot }$, respectively, and radii $<1$ pc. Sub-fragmentation into lower mass clumps is inhibited because hydrogen atoms cannot cool the gas significantly below its initial temperature. These circumstances lead to the formation of supermassive stars that inevitably collapse to make massive seeds of supermassive black holes. The simulated box size is 200 pc on a side.
