Launched in June 2024, SVOM (Space-based multi-band astronomical Variable Objects Monitor) is a joint Sino-French space mission dedicated to the study of gamma-ray bursts (GRBs) and the rapidly varying high-energy Universe. By combining wide-field instruments (ECLAIRs and GRM) with narrow-field X-ray and optical telescopes (MXT and VT), SVOM implements a coordinated, multi-wavelength strategy supported by rapid onboard triggering and ground-based follow-up. In its first two years of operations, SVOM has demonstrated substantial scientific return, extending well beyond its core GRB program. The mission has delivered a rich sample of transient and variable phenomena, including the detection and characterization of gamma-ray bursts, potentially unveiling previously underexplored soft GRB populations; type I X-ray bursts from accreting neutron stars; major outbursts from blazars; and state transitions in Galactic X-ray binaries. This seminar will present highlights from SVOM’s early operations and discuss its emerging role as a key facility for probing the dynamic high-energy sky.
