Saturn’s giant rings make it the most easily recognisable planet in the solar system. But what if Earth had a ring system of its own? The answer might surprise you. New evidence suggests that half a billion years ago, Earth actually did have its own rings encircling the planet. What would they have looked like from the ground? And could Earth ever develop a spectacular set of rings again in the future?

Astrum investigates geological evidence suggesting Earth was once encircled by a ring system similar to Saturn's. This examination explores how these rings may have influenced planetary climate, impacted the geological record, and shaped the environmental conditions of our world millions of years ago.
