What’s true for optical astronomy is also true for gravitational wave astronomy: The more observatories you have, the better your view of the sky. This is why the list of active gravitational wave observatories is growing. But so far they are all in the Northern Hemisphere. As a recent article on the arXiv preprint server points out, that means we are missing out on a good number of gravitational events.
