Happy 91st Pluto

Once a planet Pluto marks its 91st anniversary of discovery on February 18, 2021. Take a moment to ponder 91 years of Pluto from discovery to New Horizons mission majesty. Kudos Pluto, your presence is a source of infinite wonder. It’s remarkable to consider Pluto, a solar system constant, has only been known for 91 years. Arizona’s Lowell Observatory is recognized as the birthplace of Pluto. From – Celebrate the 91st anniversary of Pluto’s discovery | Human World | EarthSky

“Lowell Observatory bills itself as the the “Home of Pluto.” Percival Lowell, a wealthy American businessman with a passion for astronomy, postulated the existence of a “trans-Neptunian object” and searched for it until his death in 1916. His estate, managed by Lowell’s brother, Harvard University president A. Lawrence Lovell, donated money for a new telescope that still stands at the current Lowell Observatory. Using this telescope, Clyde Tombaugh continued Lowell’s search. On February 18, 1930, he detected movements on photographic plates taken in late January. The discovery was announced on March 13, 1930, on what would have been Lowell’s 75th birthday.”
