A couple months ago, NASA revealed the first ever image of a black hole. As something that absorbs all light, a black hole by definition cannot be seen. But using an international network of radio telescopes and custom software to interpret the data, scientists were able to analyze a broad spectrum of energies coming from the center of galaxy M87. The research is a gift that will keep giving, as they will be able to dissect the data they collected even further to better understand how the black hole works based on how it emits the energy.
