A report in Nature shows it has a mass some 17 billion times that of our Sun.

The surprise finding is hard to reconcile with existing models of black hole growth, which hold that they evolve in tandem with host galaxies.

Getting to grips with just how large black holes are is a tricky business - after all, since they swallow light in their vicinities, they cannot be seen.
