This page shows you the observed images of Saturn in the season of 2021.
The Saturn has been positioned in the constellation of Capricornus, had the opposition on Aug 2 in fairly high up of the southern skies in summer. And you can appeciate he glittering Jupiter positioned at just eastern constellation of Aquarius; we can enjoy two giant planets simultaneously. The Saturn's ring has been opened in north with a well-proportioned shape, the detailed structures like the Cassini's gap can be observed easily.
