Clyde Tombaugh, born in 1906 and gone in 1997, is a name forever etched in the annals of astronomy. He wasn't a prodigy, a wealthy scion of science, or a member of any prestigious institution. He was an amateur astronomer, a farmer's son with a burning passion for the stars, whose dedication and skill led to one of the most significant discoveries in the history of our solar system.
Tombaugh's journey began with a deep love for the cosmos. He built his own telescope and meticulously documented the night sky, showcasing a talent for observation and meticulousness. This talent caught the eye of Percival Lowell, founder of the Lowell Observatory in Flagstaff, Arizona. Lowell had long theorized about the existence of a "Planet X" beyond Neptune, a hypothetical world that could explain gravitational anomalies observed in the orbit of Uranus.
In 1929, the Lowell Observatory, still seeking this elusive planet, hired the young and relatively unknown Tombaugh. Equipped with a state-of-the-art blink comparator, Tombaugh embarked on a meticulous search, painstakingly comparing photographic plates of the night sky to identify any minute movement that could indicate a new celestial body.
His perseverance paid off. On February 18, 1930, after a year of painstaking work, Tombaugh discovered Pluto. His discovery, confirmed by other observatories, was announced on March 13, 1930, forever cementing his name in the annals of astronomy.
Despite his groundbreaking discovery, Tombaugh's work didn't stop there. He remained at the Lowell Observatory for many years, continuing his search for other planets and minor Earth satellites, though these pursuits proved unsuccessful. During World War II, he served his country at White Sands Missile Range, developing telescopic methods for tracking ballistic missiles.
After the war, Tombaugh accepted a position at New Mexico State University in Las Cruces, where he taught for the rest of his career. He became a beloved professor, known for his infectious enthusiasm and dedication to inspiring young minds. He became Professor Emeritus, serving as a guiding force for generations of students.
Clyde Tombaugh's legacy is remarkable. He was an amateur astronomer who rose to the challenge, defying the odds to discover a new world. His story is a testament to dedication, perseverance, and a boundless passion for the mysteries of the universe. He remains a true inspiration, showing us that anyone, with a bit of luck and a lot of hard work, can leave a lasting mark on the world of science.

Instructions: Imagine you are a young amateur astronomer in 1929. You are fascinated by the night sky and want to make a contribution to astronomy. Write a short paragraph explaining how you would approach the search for "Planet X" if you were offered a position at the Lowell Observatory.
There are many possible answers, but a good one would include: * Mentioning the tools and techniques you would use (telescope, blink comparator, photographic plates). * Showing understanding of the challenge involved in detecting a faint, distant object. * Emphasizing your passion for the search and dedication to finding the elusive planet. For example: "I would approach the search for "Planet X" with meticulous attention to detail and an unwavering spirit of discovery. I would utilize the observatory's powerful telescope, the blink comparator, and a system of photographic plates to carefully compare images of the night sky over time. I understand the challenge of detecting a faint, distant object, but my passion for astronomy and my unwavering dedication will guide me through the arduous process. I am eager to contribute to the quest for this unknown world and add my name to the annals of scientific history."
