    This is your Astronomy Tonight podcast.

    On this day, October 11th, in the year 1846, a groundbreaking discovery shook the astronomical world to its core. William Lassell, a beer brewer turned astronomer, pointed his homemade 24-inch reflector telescope towards the newly discovered planet Neptune and spotted something extraordinary - a moon!

    This wasn't just any moon, folks. This was Triton, Neptune's largest satellite and one of the most fascinating objects in our solar system. Imagine Lassell's excitement as he realized he was the first human to lay eyes on this icy world, barely two weeks after Neptune itself was discovered.

    Triton is a rebel with a cause, orbiting Neptune in the opposite direction of the planet's rotation. It's the only large moon in our solar system to do so, leading astronomers to believe it was once a dwarf planet captured by Neptune's gravity. Talk about a cosmic kidnapping!

    But wait, there's more! Triton is one of the coldest known objects in our solar system, with surface temperatures plummeting to a bone-chilling -235°C (-391°F). That's colder than your ex's heart and almost as frigid as liquid nitrogen! Despite this deep freeze, Triton isn't a quiet, inactive world. It's home to cryovolcanoes that spew nitrogen geysers up to 8 kilometers high. Imagine that - ice volcanoes erupting in the depths of space!

    Triton's discovery on this day marked a significant milestone in our understanding of the outer solar system and opened up a whole new realm of questions about planetary formation and evolution. So the next time you're enjoying a cold brew, raise a glass to William Lassell and his serendipitous spotting of this enigmatic moon.
