24272The Virgo interferometer is located in the south of Pisa in Italy. The main building in which the laser beam is generated, sent into the interferometer arms, and measured on photodiodes is visible at the bottom of the images. The buildings around the two 3 kilometer long arms are visible: the laser beam propagates all the arms and is reflected by a mirror
suspended in a building at each end.

10031Since 2007, the data from the LIGO, GEO and Virgo detectors are shared and analyzed together as from a single "telescope". Sharing the data is of main importance to reject local perturbations in the data and to localise the gravitational wave in the sky, i.e. to make astronomy.
