From geosphere to cosmos December 2, 2010 -   EN Excerpt from the program The completion of the ANTARES high-energy neutrino telescope in the deep Mediterranean Sea has enabled a large program of synergetic research in the fields of Earth and Sea sciences. Located at a depth of…
First Antares 5-line events / Premiers événements à  5 lignes November 30, 2010 - The size of the coloured sphere is proportionnal to the amount of light received by the optical module (in fact to the electric charge obtained from the photomultiplier). The colour of the sphere depends on the arrival time. Before and…
A secondary junction box on Antares October 30, 2010 -   EN On the 30th October 2010, the IFREMER remotely operated submersible, VICTOR, has successfully connected onto the ANTARES infrastructure a new secondary junction box (SJB) dedicated for the operation of interdisciplinary Earth and Sea science projects. The SJB, developed…
A first look at the sky June 6, 2009 -   EN Since 2007 ANTARES scrutinizes the sky in the search for neutrinos of a cosmic origin that could witness the most violent phenomena in the Universe. At present, more than one thousand neutrinos have been detected, enabling the first…
Antares back to life after a cable incident September 6, 2008 - September 6th, 2008 Antares back to life after a cable incident On June 24th, 9:40 AM, the shift crew reported a general power failure of the detector. After investigations, it became evident that this was due to the 40 km…
