"NASA's Black Hole Week: Mind-bending Visuals and Terrifying Scale"

NASA has released an animation that showcases the scale of supermassive black holes, which are believed to exist at the center of most large galaxies. The animation features 10 supermassive black holes of increasing mass, including Sagittarius A* and the black hole at the core of the galaxy Messier 87. The animation compares the sizes of the black holes' shadows to the widths of structures in our solar system. Collisions between supermassive black holes could be the key to understanding how they grow, and NASA is working on a space-based gravitational wave detector to better understand these events.
