Galileo first observed Saturn in 1610, but he couldn't understand what he was seeing - his telescope showed strange "handles" on either side of the planet. By 1612, these appendages had disappeared, baffling him completely.
In 1655, almost exactly one Saturn return later (29.5 years), Christiaan Huygens used a better telescope and correctly identified the rings. The disappearance Galileo witnessed was Saturn's rings appearing edge-on from Earth's perspective.
This celestial timing mirrors the astrological concept of Saturn returns bringing clarity and maturity to situations.
