It's Time for a Gravitational Wave Observatory in the Southern Hemisphere
Updated: 2023-08-30 14:48:25
All current and planned gravitational wave observatories are located in the northern hemisphere, in the US, India, Europe, and Japan. Even the next-generation observatories like Cosmic Explorer 40-km and the Einstein Telescope will be in the north. But a telescope in the southern hemisphere would provide a much larger baseline, allowing the detection of fainter gravitational waves. A new paper makes the case for building an observatory south of the equator.

It’s close enough and prominent in the northern sky that amateur astronomers have shared stunning pictures of it for decades .
