Sort**How does interferometry work?**   ![NRAO: interferometry](/sites/g/files/omnuum3116/files/styles/hwp_1_1__960x960_scale/public/eht/files/NRAO_interferometry_graphic.gif?itok=2KJk_hgq) 

 

*Black holes are so so tiny on the sky that any effort to image a black hole requires a team of telescopes, all working together, using a technique called interferometry. This graphic from the National Radio Astronomy Observatory (NRAO) explains interferometry and how collaborations like the EHT use it observe black holes.*







Sort**The Shape of A Black Hole Shadow**   ![EHT infographic showing a simulation of a black hole](/sites/g/files/omnuum3116/files/styles/hwp_1_1__720x720_scale/public/eventhorizon-shadows.jpg?itok=BWqHXti3) 

 

*This infographic shows a simulation of the outflow (bright red) from a black hole and the accretion disk around it, with simulated images of the three potential shapes of the event horizon’s shadow. Credit: ESO/N. Bartmann/A. Broderick/C.K. Chan/D. Psaltis/F. Ozel*







Sort**The Anatomy of a Black Hole Accretion System**   ![Infographic labelling the parts of a black hole](/sites/g/files/omnuum3116/files/styles/hwp_1_1__960x960_scale/public/black-holes-infographic-v2.jpg?itok=_Fy-DZX4) 

 

*This artist’s impression depicts a rapidly spinning supermassive black hole surrounded by an accretion disc. This thin disc of rotating material consists of the leftovers of a Sun-like star which was ripped apart by the tidal forces of the black hole. Shocks in the colliding debris as well as heat generated in accretion led to a burst of light, resembling a supernova explosion. Credit: ESO, ESA/Hubble, M. Kornmesser/N. Bartmann*
