The discovery of Pluto
At that time, astronomers Lowell and Picolin had predicted the ninth major planet in the solar system (confirmed asdwarf planet）The existence of, but no one found it.ThompsonA comparison method was used to compare the pictures of various parts of the starry sky taken at different nights in order to find objects moving in the fixed position of the star background. Finally, on February 18, 1930, Pluto was discovered by using the pictures taken in January of that year.
When asking for the names of the newly discovered planets, a British 11 year old girl, Vennettia Bonnet, finally adopted her suggestion, which was the name of the Pluto in Roman mythologyPlutoAt the same time, the first two letters are the initials of Lowell's name.The planet was officially named Pluto on May 1, 1930.
On August 20, 1949, Tang BoNew MexicofindUFOAccording to his description, there are 6 to 8 rectangular light spots, "I doubt that this can be any phenomenon on the earth..." At that time, many people also witnessed this phenomenon.Tombaugh is probably the most famous astronomer who has seen UFOs.
After 1948, he also described seeing three "green fireballs" when observing the skyOrigin of the EarthThe phenomenon is that science is not respected.
In 1949, he told the Navy missile commander that he had discovered a special light spot on Mars in the summer of 1941, and suspected that it was an atomic bomb explosion.

Its mission was to take pictures of Pluto and collect data.[1]

Clyde William Tombaugh was the first person to discover Pluto. In 1877, David Peck Todd, an astronomer at the Naval Observatory in Washington, USA, made an analysisUranusOrbitalresidualThen, use the 66cm telescope of the station to start visual search for thisOverseas planets, but nothing.
17 years later, in 1894, American astronomer Percival·Lowell stayArizonaA private observatory, Lowell Observatory, was built near Ferragastav, with an altitude of 2210 meters.Since then, he has devoted himself to studying and searching overseas planets there.On his deathbed, he firmly believed in his prediction made in May 1909.Thirteen years later, in January 1929, Clyde William Tombaugh inherited Lowell's career.
Clyde William Tombaugh was born in 1906. He loved astronomy when he was young and made a telescopeAstronomical observation。When he arrived at Lowell Observatory, he began to search for planets.At that time, the platform length also specially built a 33cm reflective typeAstrograph。After the hard work of Clyde William Tombaugh day and night, we finally filmed it on the night of January 23 and 29, 1930GeminiThere is an unknown new planet in the nearby sky.Astronomers at that timePercival Lowell andWilliam Henry PickeringThe existence of the ninth major planet in the solar system has been predicted, but no one has found it.Clyde William Tombaugh usedFlash comparatorIn order to find the objects moving in the background stars, we planned to compare the photos of the same sky taken in different nights.On February 18, 1930,ThompsonPluto was discovered in two photos taken in Gemini on January 18 and 23 of that year.SlaverThe head of the station immediately made further observations to confirm that on March 13, 1930, he finally officially announced the discovery of aOverseas planets。On May 1, 1930, President Sleffe decided to take the suggestion of an 11 year old female student in Cambridge, England, and name it Pluto, the name of the god of the underworld in Roman mythology.In Chinese, the name of planet Pluto is translated as Pluto.

NASANew Horizons The Pluto probe will fly over Pluto in July 2015, and scientists are ready to observe this dwarf planet outside the solar system.New Horizon also carries a special load, which is the ashes of Clyde Tombaugh, the discoverer of Pluto. The weight is about oneounce。
After the death of Clyde Tombaugh, in memory of himNew Horizon detectorWith his ashes on board.according toNew Horizons New Horizon will fly out of the solar system with the ashes of Clyde Tombaugh.Although Pluto is a dwarf planet, scientists are increasingly interested in it. Pluto is surrounded by many satellites, the largest of which is namedCharonIt has left a huge shadow on Pluto. In recent years, Hubble Space Telescope has found that Pluto has many satellites, even a debris ring.[3]
