The Large High-Altitude Air Shower Observatory (LHAASO) opened the multi-TeV era in 𝛾astronomy and cosmic ray physics. Since July 2021, LHAASO is fully operational and collecting high-quality data. A Nature paper in 2021, revealing 12 VHE new sources, was just the start of LHAASO science, revealing the huge scientific potential of LHAASO. Many analysis efforts are ongoing in different areas and several results are already published. In this contribution, we will show some highlights from LHAASO science in particular on the Crab SED at PeV energies, the new limits on the Lorentz Invariance Violation and Dark Matter.
