This interferometer, consisting of two straight arms that each extend outward for three kilometers near Pisa, has been upgraded with new optics and electronics and given greater protection from external forces such as seismic shocks. The objective of the project, which lasted five years and cost \u20ac24 million, was to increase the instrument\u2019s sensitivity by a factor of 10. It will enable Virgo to join the two LIGO detectors operating in the United States, which were responsible for confirming the existence of gravitational waves in 2016. Despite the announcement of the start of its second phase, Advanced Virgo is not yet operational. Problems with its new 0.4-millimeter-thick glass threads are expected to delay full operation for months.
