  The Fermi Gamma-ray Space Telescope was launched more than 13 years ago and
since then it has dramatically changed our knowledge of the gamma-ray sky. With
more than three billions photons from the whole sky, collected in the energy
range between 20 MeV and more than 300 GeV, and beyond 6,000 detected sources,
LAT observations have been crucial to improving our understanding of particle
acceleration and gamma-ray production in astrophysical sources. In this
proceeding, I will review recent science highlights from the LAT. I will focus
on the recent source catalog release, as well as on the main transient
phenomena seen with the LAT with multi-wavelength and multi-messenger
connection.
