The ANTARES neutrino telescope is the largest operating undersea neutrino telescope. It is located in the Northern hemisphere, 40 km far from Toulon, in the Mediterranean Sea. The detector array consists of 12 detector lines holding a total of 885 Optical Modules (OMs) and is located at a depth of about 2500 m. Its main scientific goal is the detection of high energy cosmic neutrinos through measurement of Cherenkov radiation from neutrino-induced charged leptons. Since the completion of the detector in 2008, analysis of the ANTARES data has been continuously improving. Further investigation covers other high energy researches and Earth and sea science studies. The various prospects and current status of the analysis are presented
