The ALICE experiment is devoted to the study of the Quark-Gluon Plasma (QGP), a deconfined state of strongly interacting matter produced in ultra-relativistic lead-lead collisions at the LHC. A selection of recent ALICE results, shedding light on the QGP properties and on the dynamics of its constituents, will be presented. In particular, results from the soft sector (bulk particle production and correlations) and from hard probes (heavy-flavor hadrons and jets) will be summarized. The physics programme of the ALICE experiment also includes the study of proton-proton and proton-lead collisions. Results will be reported also for these collision systems, originally intended as reference systems for evaluating the QGP effects on the particles produced in lead-lead collisions. In this view, particular focus will be given to measurements suggesting an unexpected onset of possible collective effects also in high-multiplicity proton-lead collisions. Physics perspectives after the detector upgrade, currently ongoing, will also be discussed.
