There are supermassive black holes. There are stellar mass black holes. And based on the idea that galaxies evolve as they merge, there should be black holes in between -- intermediate mass black holes. However, finding these middle-of-the-road beasts has been difficult. Now, a new paper in Nature identifies the first ever mid-size sedan in a universe of compact cars and SUVs. This black hole resides in the center of the Omega Centauri star cluster, which is thought to be the core of a galaxy that merged with the Milky Way billions of years ago. Deputy Director of the Carl Sagan Center Simon Steel chats with lead author Maximilian Häberle (Max Planck Institute for Astronomy) about just what this discovery means for astrophysics and galaxy evolution.
