  We report the discovery of two well-defined tidal tails emerging from the
sparse remote globular cluster Palomar 5. These tails stretch out symmetrically
to both sides of the cluster in the direction of constant Galactic latitude and
subtend an angle of 2.6 degrees on the sky. The tails have been detected in
commissioning data of the Sloan Digital Sky Survey (SDSS), providing deep
five-color photometry in a 2.5 degrees wide band along the equator. The stars
in the tails make up a substantial part (~1/3) of the current total population
of cluster stars in the magnitude interval 19.5 < i* < 22.0. This reveals that
the cluster is subject to heavy mass loss. The orientation of the tails
provides an important key for the determination of the cluster's Galactic
orbit.
