Astrophysical transients, such as gamma-ray bursts (GRBs), supernovae, and other short-lived phenomena, represent some of the most extreme and dynamic events in the universe. To study these transient sources, it is essential to have missions capable of rapidly detecting and monitoring them across multiple wavelengths. Launched in 2024, SVOM (Space-based Multi-band Astronomical Variable Objects Monitor) is a mission resulting from a collaboration between France and China. The satellite is equipped with a suite of onboard instruments designed to quickly detect and monitor new transient sources, sending real-time alerts to ground stations. Furthermore, a network of ground-based telescopes is available to provide multi-wavelength follow-up observations of these sources. While SVOM is particularly focused on gamma-ray bursts (GRBs), the first year of data collection has demonstrated its ability to contribute significantly to the monitoring of a wide variety of transient sources. In this presentation, I will provide an overview of the SVOM mission, highlighting its unique capabilities for real-time detection and follow-up of transient events. I will also present the mission's initial scientific results, illustrating its success in monitoring transient phenomena. These early results underline SVOM’s potential to enhance our understanding of the most energetic and ephemeral events in the universe.
