These black hole hunters have taken the search to a new level.  Here is a bit more on the event horizon telescope and how these astronomers are using it:

“For most people, seeing is believing,” Dr. Agol said at the time. But there was a problem getting measurements any finer. The ionized electrons and protons in interstellar space scattered the radio waves into a blur that obscured details of the source. “It’s like looking through frosted glass,” Dr. Doeleman said.

To see deeper into the black hole shadow, they needed to be able to tune their radio telescope to shorter wavelengths that could penetrate the haze. And they needed a bigger telescope. The bigger the antenna, the higher resolution or magnification it can achieve.
