Astronomers generate image equivalent to telescope 63,000 miles wide

The cosmos came into sharper focus this week with astronomers releasing the highest resolution astronomical image yet. The product of 15 earthbound radio telescopes and a Russian satellite, the image of a black hole in a galaxy 900 millions light years away is detailed enough to show the equivalent of a US 50-cent piece on the Moon.

According to Instituto de Astrofísica de Andalucía (IAA-CSIC), which is leading the project, the image is the product of six European radio telescopes, the nine dishes of the US National Science Foundation’s Very Long Baseline Array (VLBA), and the Spektr-R satellite of the RadioAstron mission.

Note how points become ellipses. The narrowest part of the ellipse comes from the widest part of the radio telescope array. I wonder if its possible to apply blind deconvolution to get an even sharper image.
