A recent $200-million upgrade of LIGO helped scientists detect the gravitational waves. One of the components in the upgrade was the installation of high-performance optical mirrors, many of which were coated by researchers from CSIRO.
The mirrors are among the most uniform and highly precise ever made, which ensures that LIGO's laser remains clean and stable as it travels through the detectors.
