Hvad skal der til for at tage et billede af et sort hul?

Hvad skal der til for at tage et billede af de sorte hul i centrum af vores galakse Mælkevejen? I videoen her forklarer vi, hvordan Event Horizon Telescope (EHT) fungerer, og hvordan det er lykkes for astronomerne at skabe et enormt teleskop på størrelse med hele Jorden, så det er stort nok til at kunne se helt til kanten af de sorte huller.
