Mimas: The Death Star Moon's Cosmic Discovery

This is your Astronomy Tonight podcast. On this day, September 17th, in the year 1789, the astronomical world was set abuzz by the discovery of Saturn's moon Mimas by the renowned British astronomer William Herschel. Picture this: Herschel, peering through his homemade 40-foot telescope, suddenly spots a tiny speck of light near Saturn's rings. Little did he know that this speck would become one of the most recognizable moons in our solar system! Mimas, affectionately nicknamed the "Death Star moon" due to its uncanny resemblance to the iconic Star Wars battle station, has captivated astronomers and sci-fi fans alike for centuries. With a diameter of just 396 kilometers, this little moon packs a big punch in terms of intrigue. Its most striking feature is the enormous Herschel Crater, which spans nearly one-third of the moon's diameter and gives Mimas its distinctive appearance. But here's where it gets really interesting: Mimas is believed to have a global subsurface ocean beneath its icy crust! This discovery, made in 2014, has led scientists to speculate about the potential for life in this unlikely place. Who would have thought that Herschel's tiny speck of light could hold such secrets? So, the next time you're stargazing and catch a glimpse of Saturn, remember that orbiting around it is a small moon with a big crater and potentially even bigger mysteries waiting to be unraveled. William Herschel's discovery on this day in 1789 continues to inspire and excite astronomers over two centuries later.
