Astronomy Tonight for - 10-24-2024

On October 24th, 1851, a significant event in astronomy occurred that would change our understanding of the solar system forever. On this day, William Lassell, a British astronomer, discovered Ariel and Umbriel, two of Uranus' moons. Lassell, a beer brewer by trade and an amateur astronomer by passion, had built his own 24-inch reflecting telescope – quite an impressive feat for the time! This homemade telescope was so powerful that it rivaled many professional observatories of the era. On that fateful night, Lassell was observing Uranus when he noticed two tiny points of light orbiting the planet. These would later be confirmed as moons and named Ariel and Umbriel, after characters in Alexander Pope's poem "The Rape of the Lock." Now, let's have a little fun imagining this discovery: Picture Lassell, his eye glued to his telescope, probably sipping on some of his own brew (for scientific purposes, of course). Suddenly, he spots something and spits out his beer in excitement. "Great hops and barley!" he might have exclaimed, "I've found not one, but TWO new moons!" He probably danced a little jig around his telescope, careful not to bump it, before rushing to document his findings. One can imagine him scribbling furiously by candlelight, occasionally glancing back through the telescope to make sure the moons were still there and he wasn't hallucinating from too much "quality control" of his beer. Little did Lassell know that his discovery would inspire future generations of astronomers and space enthusiasts. Today, we've sent probes past Uranus, and we know that the planet actually has 27 known moons. But on that October night in 1851, Lassell doubled the known moon count of Uranus from two to four, forever changing our view of this distant, icy world. So next time you're enjoying a cold one, raise a glass to William Lassell, the beer brewer who brewed up some astronomical history on October 24th, 1851!
