About the Discovery of Pluto
Environment Space & The Outdoors , United States
Ends: Feb 18, 2024
DESCRIPTION:
Pluto was discovered on February 18, 1930. Percival Lowell inspired the search for it, a man ridiculed for his belief in Martians. The discovery is explained by astronomer and author Ken Croswell in an interview with EarthSky.
____________
“In 1929, Lowell Observatory hired a young man Kansan, Clyde Tombaugh. And he implemented a search for Pluto. Tombaugh was using a telescope that took photographic plates of the sky. During the day, he would examine those photographic plates for a moving object. The word ‘planet’ actually means ‘wanderer,’ something that moves night-to-night in the way that stars don’t.
On February 18, 1930, a little after 4 p.m. Mountain Time, he saw Pluto for the very first time. And his first words to himself were, ‘That’s it!’
The discovery of Pluto was inspired by Percival Lowell and is a testimony to the hard work that Clyde Tombaugh put into searching millions of stars to find this tiny, faint object in space.”
