"The planet was discovered by the European Southern Observatory's telescope in La Silla, Chile, which has a special instrument that splits light to find wobbles in different wavelengths. Those wobbles can reveal the existence of other worlds."
That's where i found out about it and I was wondering what the name of the instrument is.
was found on this website:

ESO uses an instrument they call HARPS, for High Accuracy Radial velocity Planet Searcher. It's basically a very sensitive spectrograph that can detect the very small shifts in spectral line frequency due to the small variations in a star's radial velocity caused by orbiting planets.
