A fresh analysis of data collected by NASA’s WISE telescope has cast doubt on the widely accepted unified model for the composition of black holes. The study examined 170,000 supermassive black holes, and will require scientists to present new theories on the structure of these stellar giants.

At the center of each galaxy lies a supermassive black hole. The gravity of this all-consuming behemoth is so great that even light is unable to escape the event horizon. However, despite this, we are still able to observe them. This is because the gas that a black hole feeds on and uses to grow bigger becomes extremely hot as it nears the…
