This weekend, Saturn’s stunning rings will almost vanish from sight as they line up edge-on with Earth. This rare event, called “ring plane crossing,” happens once every 13 to 15 years. It will take place on Sunday, March 23, at 12:04 p.m. EDT (1604 GMT), according to In-the-Sky.org.
Sadly, many skywatchers won’t get to see this phenomenon clearly. For folks in mid-northern latitudes, Saturn will be low in the sky, close to the sun at dawn. Those in mid-southern latitudes have a better chance but will have to contend with early morning twilight. If you live in these regions, look to the eastern horizon just before sunrise for your best shot at spotting Saturn.
Now, why do Saturn’s rings seem to disappear? Saturn takes 29.4 Earth years to orbit the sun and has an axis tilted at 27 degrees. This tilt causes varying views of the rings throughout its orbit. Sometimes they are prominently displayed, and at other times, like now, they are seen edge-on, making them hard to see or just a thin line.
Saturn’s rings, primarily made of water ice and some rock and dust, are believed to be leftovers from comets and moons that got too close to the planet. They span an incredible 170,000 miles (273,600 kilometers) across, but are only about 30 feet (10 meters) thick. This thinness is why they almost disappear when viewed from the edge.
The rings have been shifting to this edge-on position over the past seven years, but don’t worry—this view will soon change. In just a few hours after this weekend, the rings will begin to tilt back toward Earth. They will gradually become more visible. By 2032, they’ll be at their best position for viewing once again.
Despite the temporary disappearance of the rings, the bright planet is still a sight to behold. For those eager to see Saturn at its brightest, mark your calendars for September 21, 2025. On this date, Earth will sit directly between the sun and Saturn during a phenomenon known as opposition, making Saturn shine the brightest in our night sky.
This event not only sparks excitement among astronomers but also amongst casual skywatchers. Social media is buzzing with anticipation and tips on how to spot Saturn, even without its rings. As the weekend approaches, many are eager to share their observations and experiences.
In the world of astronomy, such alignments can inspire future research. As mentioned by astronomer Dr. Jane Holloway, “We learn so much about the dynamics of planetary systems from observing events like these.” These rare moments remind us of the beauty and complexity of our solar system.
