On March 13, 1781, William Herschel peered through his telescope and spotted Uranus. It was a groundbreaking moment in the world of science, but there was more to its significance than just the discovery itself.
Firstly, the telescopes of that era were quite basic. Herschel’s homemade instrument was essentially a tube-shaped magnifier, especially when compared to the advanced, high-powered telescopes of today that scan the skies.
Secondly, Herschel was relatively new to the field of astronomy. Having spent much of his early life as a talented composer and musician, he only began to explore the stars at 34. A few years later, while observing the Gemini constellation, Herschel thought he had found a comet. However, the object, which appeared as a slow-moving disk, did not fit the characteristics of a comet. Continued observation revealed that Herschel had, in fact, discovered a new planet—the first to be found using a telescope.
As the discoverer, Herschel believed he had the right to name the planet. He proposed Georgium Sidis—meaning “George’s Star”—in honor of his benefactor, King George III. However, his peers advocated for a more refined and less nationalistic name. They chose Uranus, in keeping with the tradition of naming planets after ancient gods.
In Greek mythology, Uranus is the primordial god of the sky and the consort of Gaea, the goddess of the Earth. Their numerous offspring included the Titans, deities who dethroned their father and made Cronus, the youngest Titan, the ruler of the cosmos. Cronus (known as Saturn in Roman myth) was later overthrown by his son Zeus and his siblings, who ascended to become the Olympian gods. With such a rich lineage, the name “George’s Star” was never going to prevail.
William Herschel would go on to identify over 2500 nebulae, introduce the term asteroid, and invent a number of new telescopes. But he didn’t accomplish all this by himself: His younger sister, Caroline, played a crucial role in every scientific venture. She polished the telescope mirrors, stayed up late to document celestial observations, and helped edit and publish his pioneering star catalogs. Caroline Herschel herself achieved remarkable feats, including the discovery of 14 new nebulae, compiling a catalog of star clusters, and identifying eight comets, among other notable accomplishments.
The discoveries made by the Herschels paved the way for groundbreaking technological and scientific advancements—and it all began with Uranus.
