NASA's Hubble Space Telescope took this image of Saturn on 22 Sept. 2022. SCIENCE: NASA, ESA, Amy Simon (NASA-GSFC) IMAGE PROCESSING: Alyssa Pagan (STScI)Theyre one of the most iconic objects in the entire solar system, but on Sunday, March 23, the rings of Saturn will disappear. The most extensive and impressive ring system we know of and a spine-tingling view through any telescope will be a non-event.Heres everything you need to know about why Saturns rings are about to disappear and when they will return.Why Saturns Rings Are DisappearingIts not that Saturns rings are actually disappearing altogether (though that will happen in about 100 million years, according to NASA, when theyll be pulled into Saturn by its gravity). It's just that they will, for a short time, become impossible to see from Earth.Earths view of the planet waxes and wanes as Saturn orbits the sun every 29 years. Saturns axis is tilted by 26.7 degrees with respect to its orbit around the sun, according to NASA similar to Earths 23.5-degree tilt which means the ringed planet has seasons. Its tilt merely means that the rings appear to open and close, as seen from Earth.Right now, the view from Earth is narrowing, and on March 23, the rings will be precisely tilted edge-on to Earth, making it impossible to view them.These Hubble Space Telescope images, captured from 1996 to 2000, show Saturn''s rings open up from ... [+] just past edge-on to nearly fully open as it moves from autumn towards winter in its Northern Hemisphere, part of the course of its 29-year journey around the Sun.

Although it wont be much of a year to observe Saturns rings, the good news is that the view from Earth will by then be widening, and destined to get wider as they tilt back toward Earth. Theyll continue to become more visible and brighter until 2032.Saturn's rings are made from dust and water particles but are around 98% ice. They're about a mile thick and stretch to 87,000 miles (140,000 kilometers) from the planet.Wishing you clear skies and wide eyes.
