"Scientists are studying the unprocessed pictures to uncover new discoveries in the gas giant's ring system.
Equinox is the moment when the Sun crosses a planet's equator, making day and night the same length.
During this time, the Sun's angle over Saturn is lowered, showing new objects and irregular structures as shadows on the otherwise flat plane of the rings.
Saturn's orbit is so vast that Equinox happens only once every 15 Earth years.
At the moment of equinox, the rings turn edge-on to the Sun and reflect almost no sunlight.
This is the first equinox since 1994 and the first time there has been an observer, in the shape of the joint US and European spacecraft, Cassini."
