Every day about five papers are published using Gaia Data Release 2 or Early Data Release 3. Gaia Data Release 3, published on June 13, 2022, will be another source of high-precision data for the astronomical research. The number of stars with 6D phase space information (astrometry plus radial velocities) for stellar dynamical investigations has increased by almost a factor of five, and for the first time more than 100 million low-resolution Bp and Rp spectra become available, providing more detailed information compared to the previous broad-band photometry. Additionally, Gaia DR3 contains special catalogues for multiple stars systems, variable star, and asteroids. Nine performance verification papers, provided by the Gaia DPAC team, demonstrate how to efficiently use the new Gaia catalogue in many different areas of astrophysical research.
