Let's unwrap another question we often get about the @ehtelescope 's #EHTblackhole image: Why doesn't the picture look like the black hole simulation in the movie Interstellar? Let's digest the differences one by one.

The streak across the Interstellar 📸 is nowhere to be seen in ours. We are looking at the #M87blackhole almost 'straight down the barrel', and in Interstellar we look at it from the side and see the disk of matter, as shown here!

Our #EHTblackhole 📸 is also not fully symmetrical. It is brighter on the bottom from its slight inclination! The radiating gas is moving very fast as it orbits the BH, so it appears brighter as it moves toward us, and dimmer when it moves away: this is the Doppler effect!
