This is a collection of observational images of Saturn from the 2025 season.
This season, Saturn is located in the western part of Pisces and reaches opposition on September 22, when it can be observed at the southern meridian in the autumn sky. On March 24, 2025, the planet's central latitude became 0°, causing the rings to appear to vanish. However, since this occurred just after Saturn's conjunction, detailed observations were not possible. From that day onward, for the first time in about 15 years, the southern side of the rings has become visible from Earth.
