Query: ARGO-YBJ: Status and Highlights   The ARGO-YBJ experiment is in stable data taking since November 2007 at the
YangBaJing Cosmic Ray Laboratory (Tibet, P.R. China, 4300 m a.s.l., 606
g/cm$^2$). ARGO-YBJ is facing open problems in Cosmic Ray (CR) physics in
different ways. The search for CR sources is carried out by the observation of
TeV gamma-ray sources both galactic and extra-galactic. The CR spectrum,
composition and anisotropy are measured in a wide energy range (TeV - PeV) thus
overlapping for the first time direct measurements. In this paper we summarize
the current status of the experiment and describe some of the scientific
highlights since 2007.
