Hinrichs History of Astronomy

Aristotle

322 BCE

384-322 Aristotle is under the geocentric model. The Sun, Moon, stars, and the planets all orbited around the Earth. The geocentric model served in the predominant description of the cosmos many ancient civilizations, such as Aristotle and Ptolemy. Two observations supported the idea of the Earth was the center of the Universe.

Ptolemy

168

100-168 Ptolemy was a Greco-Roman mathematician, astronomer, geographer plus a astrologer. He lived in a city of Alexandria. Roman province wrote in Koine Greek, and held the Roman citizenship. The formulated of the Alexandrian astronomer and mathematician Ptolemy. In the AD 150 he had recorded him in his Almagest and Planetary Hypotheses.

Copernicus

1543

1473-1543 Copernicus was a mathematician and astronomer who was a formulated model of the universe that was placed the Sun that was rather than the Earth at the center of the universe. Likelihood independently of the Aristarchus of the Samos, who had formulated a model that some eighteen centuries did earlier.

Tycho Brahe

1601

1546-1601 Tycho Brahe was a Danish nobleman, astronomer, and planetary observations. People believed that geocentric model of the universe that Earth was the censure. Danish nobleman astronomer was one of the individuals who work plus helped overturn the belief of a heliocentric model of the universe with the sun at the center.

Hans Lippershey

1619

1570-1619 Hans Lippershey was a German-Dutch spectacle-maker. He is commonly associated with the invention of a telescope because he was the first one who tried to be a patent for it. It is, however it was not clear if Hans Lippershey was the first one who had built the telescope.

Johannes Kepler

1630

1571-1630 Johannes Kepler is a German astronomer, mathematician, and astrologer. He is the key to figure in the 17th-century scientific revolution and is best known for his laws of planetary motion plus his books that he wrote were Astronomia nova, Harmonices Mundi, and Epitome Astronomiae Copernicanae.

Galileo

1642

1564-1642 Galileo was an Italian astronomer, physicist and engineer, sometimes described a polymath. Galileo has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science" those were all the things that Galileo was called.

Refracting and Reflecting telescopes

1686

A reflecting telescope is a telescope that uses a single or a combination of curved mirrors that can reflect light and form an image. Then a Refracting telescope is type of optical telescope that can use a lens as its objective to form an image the refracting telescope is design to originally spy glasses that is a astronomical telescopes but is also used for long focus camera lenses.

Giovanni Cassini

1712

1625-1712 Giovanni Domenico Cassini is an Italian mathematician, astronomer and engineer. Cassini is known for his work in the fields of astronomy and engineering Astronomer Giovanni Cassini is associated with a number of scientific discoveries plus projects including the first ever observations of Saturn's moons. However he also used the name Gian Domenico Cassini after he moved to France as a adult.

Sir Isaac Newton

1724

1643-1724 Sir Isaac Newton was contributed in the field of science over his lifetime. He invented the calculus and provided an clear understanding of optics. But his most promising work had to do with forces plus specifically with a development of a universal law of gravity.

William Herschel

1822

1738-1822 Sir William Herschel is a British astronomer and composer. Who is the founder of sidereal astronomy that was for observing the heavenly bodies. He found the planet Uranus plus its two moons and formulated the theory of the stellar evolution. William Herschel is a

Percival Lowell

1916

1855-1916 Percival Lowell American astronomer who predicted an existence of the planet beyond the orbit of Neptune and then initiated of search ended in the discovery of Pluto. Percival Lawrence Lowell is an American businessman plus a author a mathematician and astronomer who fueled speculation that were canals on Mars. He founded the Lowell Observatory in Flagstaff Arizona and was formed the beginning of the effort that had led to the discovery of Pluto 14 year then after his death.

John Glenn

1921

1921-2016 John Glenn was one of the Mercury Seven in the military test pilots selected in 1959 by NASA and was remember as the nation's first astronauts. On February 20, 1962, Glenn had to fly a mission called the Friendship 7 plus becoming the first American to orbit around the Earth. Would be the fifth person and third American in the space.

Karl Jansky

1950

1905-1950 Karl Jansky was a American physicist and was radio engineer who first discovered radio waves emanating from the Milky Way in August 1931. He is considered the person who figured radio astronomy.

Edwin Hubble

1953

1889-1953 The astronomer Edwin Hubble determined that our Universe was expanding. For example the fabric of space between two distant galaxies are stretching just like rubber that is inflating
a balloon.

Albert Einstein

1955

1879-1955 Einstein was a great inventor who invented the Einstein refrigerator and the Gas absorption heat pump. He left school at 15 because his teacher said there was nothing left to teach him. He was really smart and worked super hard.

Sputnik

1957

1957 Sputnik installment was intended to be a space laboratory for the study of Earth's magnetic field plus its radiation belt. After the launch on May 15, 1958 it remained in orbit for two years. The Sputnik missions happened during the midst of Cold War between the U.S.S.R. and the United States.

Yuri Gagarin

1961

1961 Yuri Gagarin was the first person to go into space. His flight was o April 12,1961 and it lasted for 108 minutes as he circled the earth for a little more than one orbit in the space craft call the Soviet Union's Vostok.

Neil Armstrong

1962

1930-2012 Neil Armstrong was really famous for being the first person to walk on the moon on July 20, 1969. He also flew on the Gemini 8 mission in 1966

Ejnar Hertzsprung

1967

1873-1967 Ejnar Hertzsprung is a astronomer who classified types of stars by relating their color to their absolute brightness. An accomplishment of fundamental importance to modern astronomy.

Apollo Program

1972

1963-1972 Apollo Program was a program was made to land humans on the moon then bring them back to earth safely. Six of the missions Apollo 11, 12, 14, 15, 16, and 17 had achieved this goal. The other mission could not bring the data back.

First Space Shuttle flight

1981

1981 This was the first successful flight. That had Orbited around the earth 36 times. Two members, astronauts John W. Young, commander and Robert L. Crippen, pilot it also lifted off from Pad A,
and was a Launch Complex 39 at the Kennedy Space Center.

mars Pathfinder Expedition

1996

1996 It was designed as a technology demonstration of the new way to deliver an instrumented lander. The first-ever robotic rover to the surface of the red planet. only accomplished this goal but also returned a unprecedented amount of the data and outlived its primary design life.

Cassini orbiter

1997

1997 Cassini was one of the most ambitious missions that was ever launched into space. Loaded with an array of powerful instruments and cameras. The spacecraft was capable of taking a accurate measurements and plus detailed images in a variety of conditions and light spectra.

The Red Moon

2019

The red moon happened this year 2019. A red moon is at the same time a little bit of the light from Earth's sunrises plus its sunsets falls on the surface of the moon it is because the light waves are stretched out and then the more it looks red. He moon is fully in Earth's shadow.
