A dramatic example is Saturn, where the equinox places its [[rings of Saturn|ring system]] edge-on facing the Sun. As a result, they are visible only as a thin line when seen from Earth. When seen from above – a view seen during an equinox for the first time from the ''[[Cassini–Huygens|Cassini]]'' space probe in 2009 – they receive very little [[sunshine]]; indeed, they receive more [[planetshine]] than light from the Sun.<ref>{{cite web |url=http://photojournal.jpl.nasa.gov/catalog/PIA11667 |title=PIA11667: The Rite of Spring |publisher=Jet Propulsion Laboratory, California Institute of Technology |access-date=21 March 2014}}</ref> This phenomenon occurs once every 14.7 years on average, and can last a few weeks before and after the exact equinox. Saturn's most recent equinox was on 11 August 2009, and its next will take place on 6 May 2025.<ref>{{cite web |url=http://www.planetary.org/blogs/emily-lakdawalla/2016/06031044-oppositions-conjunctions-rpx.html |title=Oppositions, conjunctions, seasons, and ring plane crossings of the giant planets |last=Lakdawalla |first=Emily |author-link=Emily Lakdawalla |date=7 July 2016 |website=[[The Planetary Society]] |access-date=31 January 2017}}</ref> Mars's most recent equinoxes were on 12 January 2024 (northern autumn), and on 26 December 2022 (northern spring).<ref>{{cite web |url=http://www.planetary.org/explore/space-topics/mars/mars-calendar.html |title=Mars Calendar |publisher=[[The Planetary Society]]}}</ref> {{Clear}} Summary: Please note that all contributions to Christianpedia may be edited, altered, or removed by other contributors.
