Clyde Tombaugh was a self taught, amateur astronomer looking for some feedback of drawings he made based on his observations of the night sky. What he got, though, was a start in what would be a long and distinguished career in the field of astronomy and one of the most famed discoveries ever made by an American astronomer, he found the planet Pluto. Clyde Tombaugh was born in 1906 and raised in a small farming community in Streator Illinois and later moved to a family farm in Western Kansas. He had his first look through a telescope at age 14 and was hooked. He eventually began making his own telescopes and would go on to build over 30 in his lifetime. (http:starchild.gsfc.nasa.gov, Clyde Tombaugh) After building one particular telescope, one with a very accurate 9 inch reflector, he sent drawings of Jupiter and Mars to astronomers at the Lowell Observatory in Flagstaff Arizona for comments. They were so impressed with his work that they offered him a job. The Lowell observatory was working on the construction of a telescope with a 13 inch telescope and needed someone to take pictures and document the findings in a search for “Planet X”. The existence of Planet X was predicted by astronomer Percival Lowell who died in 1913. Tombaugh’s meticulous nature made him perfect for the job. By his own account he was a perfectionist, in his book, “Out of the Darkness, The Planet Pluto” he said “Nothing short of perfection would satisfy me” (117).
Only high school educated, Clyde Tombaugh went to work for the Lowell Observatory in January of 1929, in February of 1929 the 13 inch telescope was ready for use and on February 18,

    William Hershal was a telescope maker and with the invention of the telescope was the motivation that led to the discovery. Because the calculated orbit of Uranus did not compare accurately with the observed orbit, astronomers concluded that a disturbing influence was present. A study of this irregularity led to the discovery of Neptune in 1846. (Columbia Electronic Encyclopedia, 6th Edition. Q2 2016, p1-1. 1p.)…

    Clyde Tombaugh is not exactly a household name even though he discovered something that each and every one of us has learned about. He is accredited with the discovery of the now ex- planet Pluto. Clyde was born in Streator, Illinois February 4, 1907. At a young age his family moved to Kansas to start their own farm. Clyde had planned on going away to college the fall after moving to Kansas, but this was all put on hold when a hailstorm had ruined his families’ entire crop and he was forced to stay home and work on the farm. Clyde, while stuck on the farm, began to become interested in the sky and the stars, and at the age of 20, he started building his own unique telescopes and lenses to observe planets and he would draw what he saw. He would send these drawings of the planets to the Lowell Observatory in Flagstaff, Arizona. This eventually got him a job at the observatory due to his drawings impressing the director of the time Vesto Melvin Slipher. Clyde worked at the observatory from 1929 to 1945 and in this time he made his biggest discovery of finding Pluto in 1930.…

    Julie Wakefield explains, “Uranus possesses a long history of intrigue. The mysterious fleck befuddled Galileo Galilei (1564-1642). Among the first to point a telescope toward the heavens, the keen Italian observer likely spotted the faint pearl about a decade into the 17th century, but Galileo assumed it was a star, much as he had dismissed Neptune. Britain's first Royal Astronomer, John Flamsteed (1646-1719), appointed in 1675, the year the Greenwich Observatory debuted, saw the unidentified object in 1690. Flamsteed recorded it as "34 Tauri" in the constellation Taurus the Bull. A later Royal Astronomer, James Bradley (1673-1762), observed Uranus three times in the mid-18th century and dismissed it as well. And French astronomer Pierre Charles Le Monnier (1715-1799) sighted the celestial body a dozen times, with his last sighting in 1771, and never guessed it might be something other than a…

    “The New Science” was published during the Scientific Revolution, a surge in scientific discoveries and methodology during the 17th and 18th centuries. The poster seems to encourage popular participation in science, although the products shown would only be available to the elites, since they were able to spend money on them. The spread of the image was made possible by Gutenberg's printing press, which was developed in the 15th century and also helped facilitate the spread of other pieces of scientific information during the Scientific Revolution. The printing press’s effect on literacy is evident in the image of the reading glass, which makes it easier for people to read, indicating the widespread popular literacy at the time. Yarwell’s knowledge about optics and his success in making instruments like microscopes and prisms may be due to the discoveries of scientific figures like Kepler and the more recent works of Isaac Newton. The man in the poster is shown using the telescope to look at the sky, which may reflect the recent discoveries of Copernicus and Galileo, who proved the heliocentric model of the universe. Additionally, it was common…

    Galileo was a very smart man. He created and discovered many amazing things, not all of which were accepted by the beliefs of the Roman Catholic Church. He created a telescope that magnified up to 20 times and began studying space in 1609, (“Galileo”). The telescope allowed him to see many things not visible to the human eye, such as the texture of the moon and Jupiter's four moons. Through the study of his findings Galileo discovered that Venus and Mercury revolve around the sun, and that confirmed his belief that the Sun was the center of the Universe.…

    Hearing early in 1609 that a Dutch optician, named Lippershey, had produced an instrument by which the apparent size of remote objects was magnified, Galileo at once realized the principle by which such a result could alone be achieved, and, after a single night devoted to consideration of the laws of refraction, he succeeded in constructing a telescope which magnified three times, its magnifying power being soon increased to thirty-two.…
