Giga-Hertz Peaked Spectrum (GPS) and Compact Steep Spectrum (CSS) sources have compact radio morphologies (<1 to 10 kpc, respectively). They have been interpreted as either young counterparts of FR I radio galaxies or as 'frustrated' AGN, in which the radio jets are not able to penetrate the host galaxy's gas and dust. The high spatial resolution of Chandra allows us to study the environment of these sources within arcsec of the strong compact core. Here, we present the discovery of X-ray jets in the two GPS quasars, indicating that X-ray emission associated with relativistic plasma is present at large distances from the GPS quasar.
