In April 2019, a group of astronomers from around the globe stunned the world when they revealed the first image of a black hole ' the monstrous accumulation of collapsed stars and gas that lets nothing escape, not even light. The image, which was of the black hole that sits at the core of a galaxy called Messier 87 (M87), revealed glowing gas around the center of the black hole. In March 2021, the same team produced yet another stunning image that showed the polarization of light around the black hole, revealing its magnetic field. The "camera" that took both images is the Event Horizon Telescope (EHT), which is not one singular instrument but rather a collection of radio telescopes situated around the globe that work together to create high-resolution images by combining data from each individual telescope. Now, scientists are looking to extend the EHT into space to get an even sharper look at M87's black hole. But producing the sharpest images in the history of astronomy presents...
