This is your Astronomy Tonight podcast.

On October 24th, we celebrate a truly remarkable event in the history of astronomy. On this day in 1851, William Lassell, a British astronomer and beer brewer (yes, you heard that right!), discovered Ariel and Umbriel, two of Uranus's moons.

Now, imagine this: It's the mid-19th century, and Lassell, who made his fortune brewing beer, decides to use that money to pursue his passion for astronomy. He builds his own telescope - a whopping 48-inch reflector - which was, at the time, the largest telescope in the world. Talk about a hobby gone wild!

On that fateful night of October 24th, Lassell pointed his giant "beer telescope" towards Uranus and spotted two tiny dots orbiting the planet. These dots turned out to be Ariel and Umbriel, the fourth and second largest moons of Uranus respectively.

Ariel, named after a mischievous air spirit in Shakespeare's "The Tempest," is the brightest of Uranus's moons. It's covered in canyons and rifts, making it look like a giant cosmic golf ball. Umbriel, on the other hand, is named after a "dusky melancholy sprite" from Alexander Pope's poem "The Rape of the Lock." True to its name, Umbriel is the darkest of Uranus's large moons, reflecting only about 16% of the light that hits it. It's like the goth teenager of the Uranian system!

Lassell's discovery was a testament to the power of amateur astronomy and, perhaps, the inspirational qualities of a good brew. It just goes to show that sometimes, the best astronomical discoveries are made with a little bit of passion, a lot of dedication, and maybe a pint or two of beer!
