Paris – The the LISA Pathfinder probe built by ESA with the contribution of the Italian Space Agency (ASI), the National Institute of Nuclear Physics (INFN) and the University of Trento, was launched six months ago from the ESA base in Kourou in French Guiana, has fully achieved its objective, demonstrating the technological feasibility of building a space observatory for gravitational waves. “The LISA experiment is a new messenger who will bring us important information about the mechanisms that regulate the life of the Universe such as gravitational waves – said President of ASI Roberto Battiston at the presentation of the first results today at the ESA headquarters in Paris. It is an important investigation especially after the scientific collaborations between LIGO and VIRGO who have recently confirmed their existence. ” (9Colonne)
