Our place here on Earth is pretty comfortable. It's a comfortable distance from the sun, which is a comfortable size and located in a comfortable spot in the Milky Way galaxy. But at the center of our galaxy, things get pretty dicey. That's where you'll find a supermassive black hole with the heft of 4 million suns. It's called Sagittarius A*, and for decades, scientists believed that it — and every black hole at the center of every galaxy — conjured a particular type of gravitational pull that formed a "cusp" of stars and black holes around its perimeter. That's all been theoretical, however, since we've never actually observed this crowd of objects around Sagittarius A*. But for research published in April 2018, a team of researchers figured out just how to spot this black-hole party — and what they found was awe inspiring.
