Gravitational waves detected by the ground-based interferometers LIGO, Virgo and Kagra have opened the way to new scenarios and provided new tools to get a deeper understanding of our universe. One of the most promising ways to detect those signals in the future will be with a detector settled-up in the space known as Laser Interferometer Space Antenna (LISA). In this talk, we will introduce the experimental set-up, as well as its goals and the new potential sources that could detect.
