Caption: Astronomers have revealed the largest black hole merger to date. This illustration shows how the merger would appear to our eyes if we could somehow travel in a spaceship for a closer look.

Astronomers wanted to understand where any mid-sized black holes might fit in, so they began looking harder. What they discovered is that lite intermediate-mass black holes do indeed exist.

The black holes – one roughly 140 times the mass of the Sun and the other about 100 solar masses – fused into one pit of ...
