However, from time to time, Saturn\u2019s rings \u201cdisappear\u201d from view, a phenomenon known ring-plane crossing, with the rings being observed as a flat line running straight through the massive gas giant. Ring-plane crossing occurs approximately every 15 years and is slated to happen next in March 2025, with the rings slowly getting \u201clarger\u201d in the months afterwards before \u201cdisappearing\u201d again in November 2025.

As a result, our view of Saturn changes over time, and the \u201csize\u201d of the rings appear to get larger and smaller, and periodically disappear entirely from view for a short time. As noted, ring-plane crossing happens approximately every 15 years, with the most recent occurrence being observed directly from Earth happening in 2009. However, both the 2009 and 2025 events are not observable from Earth since Saturn will be too close to the Sun. <\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\">\n<p>\n<span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" title=\"saturn ring plane crossing 2008-09\" width=\"1110\" height=\"833\" src=\"https:\/\/www.youtube.com\/embed\/hnxUwVNN4WQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/span>\n<\/p>\n<\/figure>\n<p>NASA\u2019s Hubble Space Telescope captured some fantastic images of Saturn\u2019s rings edge-on in 1995, which provided astronomers the opportunity to observe some of Saturn\u2019s larger moons and try to discover new moons, as well. The reason why ring-plane crossing allows astronomers to find new moons is due to the decreased glare of the bright rings that normally obscure smaller objects orbiting Saturn from being seen. In fact, between 1655 and 1980, ring-plane crossing is responsible for astronomers discovering 13 new moons of Saturn, with additional moons of Saturn being discovered by NASA\u2019s Voyager 1 spacecraft in 1980. Two of Saturn\u2019s most well-known moons, Enceladus and Mimas (aka the Death Star), were discovered by William Herschel during the ring-plane crossing of 1789-1790, and Hyperion was discovered during the ring-plane crossing of 1848-1849.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><figcaption class=\"wp-element-caption\">Image of ring-plane crossing at Saturn taken by NASA\u2019s Hubble Space Telescope in May 1995, with a similar ring-plane crossing event scheduled to occur in March 2025.

When he observed the rings had apparently disappeared, he wrote in his notes, \u201cI do not know what to say in a case so surprising, so unlooked for and so novel\u201d.<\/p>\n<p>As noted, ring-plane crossing occurs due to the combination of the tilts of Earth and Saturn and their respective orbits, which also influences the north-south direction of the rings during the crossing. For example, the ring-plane crossing event occurring in March 2025 will see Saturn\u2019s rings proceed from south to north, but this contrasts with the ring-plane crossing event that will occur several decades from now in August 2068. For this event, the rings will proceed from north to south.<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\">\n<p>\n<span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" title=\"saturn ring plane crossing 2025 (plot spoiler)\" width=\"1110\" height=\"833\" src=\"https:\/\/www.youtube.com\/embed\/Sv_qsDYLH4Y?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/span>\n<\/p>\n<\/figure>\n<p>While ring-plane crossing causes Saturn\u2019s rings to give the illusion they are \u201cdisappearing\u201d, this illusion won\u2019t be around forever. This is because the icy grains that comprise Saturn\u2019s rings are slowly being lost to the planet with a 2019 study used ground-based observations to estimate the rings will be gone for good in approximately 292 million years. Most recently, a 2023 study used data from NASA\u2019s Cassini mission to provide a larger range of the remaining lifespan of Saturn\u2019s rings at between 15 to 400 million years.<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\">\n<p>\n<span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" title=\"Saturn&#039;s Rings Are Disappearing\" width=\"1110\" height=\"624\" src=\"https:\/\/www.youtube.com\/embed\/mN8o90UbpmE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/span>\n<\/p>\n<\/figure>\n<p>What new discoveries will astronomers make using Saturn\u2019s ring-plane crossing in the coming years and decades?
