They are just starting data collection at a higher frequency band that will allow higher resolution. Unfortunately our baseline is currently limited by the diameter of the earth so the only way to get sharper data is by using shorter wavelengths.
- dylan604 4y ago>Unfortunately our baseline is currently limited by the diameter of the earth Is there a way to use the diameter of the earth "at this point in the orbit" to effectively make it into the diameter of the earth's orbit?
- torrance 4y agoInterferometry relies on measuring the interference pattern between two points simultaneously measuring incoming radio waves. Each element of a baseline must be measured at the same time. If we were to allow the Earth to rotate around the Sun and measure components of the same baseline at different times, we would violate this.

- rcxdude 4y agoThe concept has been done, though not with such a large baseline: https://en.wikipedia.org/wiki/Spektr-R https://en.wikipedia.org/wiki/Spektr-R I don't know what exactly the tradoffs are, but I suspect this approach has a lower sensitivity due to size of the dishes, it's more difficult to get enough telescopes to form a good image, and transmitting the data back is likely to be a challenge (the black hole observations were shipped on hard drives instead of transmitted via the internet. Even achieving a broadband-speed transmission rate with a deep space object is difficult)
