On May 12th the Event Horizon Telescope Collaboration (EHTC) presented the first image of the supermassive black hole in the center of our Galaxy, Sagittarius A*, or SgrA* in our jergon. As an active member of the EHT and after two years working for obtaining this image, in this seminar I will explain you how the image was done, what difficulties we found, what can we learn and what are the future prospects.
