Here is an excellent article on the Event Horizon Telescope (EHT).
EHT is supposed to start observations next month if all goes well but as the article states, it will be months of data processing before we know if the attempt to image a black hole event horizon was successful.
On my recent voyage I was able to get a photograph of the Hawaii-based radio telescope that is part of the EHT network. It was so cool to see this clone of the Very Large Array (VLA) that was featured in the movie 'Contact' and is poised to make history with EHT.
I couldn't get my "touch history" selfie as I usually do so I had to improvise.
Tomorrow I will share my visit to Mauna Kea, HI.
