The spacebased NASA-ESA mission, LISA is expected to be launched in ten years' time. With the data around the comer exciting times lie ahead for GW astronomy. A brief introduction to GW detection, the prin- ciple of GW detection, the current status of ground based detectors, the space based detector LISA, GW sources and the data analysis necessary to extract the weak GW signal from the detector noise will be presentedenGravitational wavesInterferometric detectorsAstrophysical GW sourcesArticle
