Giovanni Virginio Schiaparelli, born in 1835 and known simply as Schiaparelli, was an Italian astronomer who made significant contributions to the field of planetary science. His meticulous observations of Mars in 1877, leading to the infamous "canals" theory, forever cemented his name in astronomical history. However, his legacy extends far beyond this controversial discovery.
Early Life and Education:
Schiaparelli's journey to the stars began in Savigliano, Italy. He studied mathematics and astronomy at the University of Turin, graduating in 1859. His talents were quickly recognized, leading him to become a professor at the Brera Observatory in Milan in 1862. He later became its director in 1872, a position he held until his retirement in 1900.
Meteors and Comets:
Schiaparelli's early research focused on meteors and comets. Through meticulous observation and data analysis, he discovered the connection between the Leonid meteor shower and the comet Tempel-Tuttle. This groundbreaking finding established the link between these celestial bodies, a crucial step in understanding the origins and nature of meteor showers.
The Mars Obsession:
While Schiaparelli's work on meteors and comets solidified his reputation, his observations of Mars truly captivated the scientific community. In 1877, during a period of favorable Martian opposition, he turned his telescope towards the red planet, meticulously documenting its surface features.
The "Canals" and Controversy:
Schiaparelli's meticulous drawings depicted a network of straight lines on Mars, which he named "canali." He believed these to be artificial channels, possibly constructed by an intelligent civilization. While he never explicitly claimed Martian life, his terminology and illustrations fueled widespread speculation and debate.
The Legacy of Schiaparelli:
Schiaparelli's "canals" later proved to be an optical illusion, a result of his telescope's limitations and the human eye's tendency to connect disparate features. However, his meticulous observations and detailed drawings laid the foundation for future Martian research.
Despite the controversy surrounding the "canals," Schiaparelli's legacy remains significant. His work on meteors and comets, his dedication to meticulous observation, and his contribution to the early understanding of Mars continue to inspire generations of astronomers. He is remembered not only as a pioneer in planetary science but also as a visionary who dared to explore the unknown, even if his observations led him down a path of misinterpretation.

Instructions: Imagine you are an astronomer in the late 19th century, working with Schiaparelli at the Brera Observatory. You are tasked with observing Mars during a period of favorable opposition.
This is an open-ended exercise where students should use their knowledge of Schiaparelli's observations and the scientific understanding of the time to come up with their own conclusions. Encourage them to consider different possible explanations and engage in critical thinking.
