Percival Lowell (1855-1916) remains a complex figure in the history of astronomy. While his legacy is often overshadowed by his erroneous theories about Martian canals, Lowell was a pioneering astronomer who made significant contributions to our understanding of the solar system.
Born into a wealthy Boston family, Lowell initially pursued a career in business. However, his true passion lay in the stars. After a personal crisis, he dedicated himself to astronomy, establishing the Lowell Observatory in Flagstaff, Arizona in 1894. This location, chosen for its high altitude and clear skies, proved to be a strategic choice for celestial observation.
Lowell's primary focus was Mars, a planet that captured the public imagination in the late 19th century. He meticulously observed and charted the planet's surface, convinced he was seeing evidence of "canals" – artificial waterways constructed by an advanced Martian civilization. These theories were widely publicized, igniting public fascination with the possibility of extraterrestrial life. However, the "canals" were later revealed to be optical illusions, a result of the limitations of early telescopes and the human tendency to find patterns in random data.
Despite this scientific misstep, Lowell's work had a lasting impact on astronomy. He was a tireless observer and an advocate for innovative techniques. He championed the use of high-quality telescopes and precise photographic methods, contributing significantly to the advancement of astronomical research.
His calculations based on irregularities in Uranus's orbit led to the prediction of a trans-Neptunian planet, which he named Planet X. Though Lowell himself died before its discovery, his meticulous work paved the way for Clyde Tombaugh's discovery of Pluto in 1930 at the Lowell Observatory.
Lowell's legacy is a testament to the complexities of scientific progress. While his belief in Martian canals proved to be wrong, his dedication to observation and research played a vital role in advancing our understanding of the solar system. It's a reminder that even flawed theories can spark scientific curiosity and contribute to groundbreaking discoveries.
Today, the Lowell Observatory continues to be a leading center for astronomical research, carrying on the legacy of its founder. While Lowell may be remembered for his Martian canals, his dedication to science and his contribution to the discovery of Pluto solidify his place as a significant figure in the history of astronomy.

Task:
Imagine you are a science journalist writing an article about Percival Lowell and his contributions to astronomy. Consider both his successes and his mistakes.
Write a short paragraph (5-7 sentences) highlighting:
Exercice Correction:
Percival Lowell was a dedicated and innovative astronomer who significantly impacted the field of astronomy. His meticulous observations and the use of advanced techniques, such as high-quality telescopes and photographic methods, contributed to a deeper understanding of the solar system. His work, despite being flawed, ultimately led to the discovery of Pluto by Clyde Tombaugh at the Lowell Observatory. Lowell's theories about Martian canals, however, have been largely discredited and are considered a significant misstep in his career. Despite this controversy, Lowell's dedication to science and his lasting legacy at the Lowell Observatory solidify his place as a significant figure in the history of astronomy.
