A year ago today, we unveiled the M87 #BlackHole image by @ehtelescope! We were so proud to finally share our hard work (by 300+ scientists & engineers) with the rest of the world! Let me tell you a little bit about the crazy journey to get here

#OTD #BlackHole1year 🥳 @ehtelescope uses the technique of very long baseline interferometry to achieve the resolution necessary to see a black hole 55 million light-years away! We synchronized 📡📡 around the world, and synthesized a virtual telescope the size of Earth!

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.

cr. EHT/Paramount Pictures ImageImage 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!
