Astrolabes In The 10th Century

1. The earth’s sun is a star, it generates heat and light through nuclear fusion.

The solar system was created 4.6 billion years ago by a gravitational collapse. A solar system is a star that has planets, moons, asteroids, comets, and meteoroids travel around it. The solar system contains eight known planets which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Neptune. There is around several hundred dwarf plants but only five are currently recognized. The solar system has about 181 moons which orbit around the planets in the solar system. There is also about 150 million asteroids and 3,406 comets also in the solar system.

While researching “pre-industrial astronomical accomplishments,” it seemed that a good majority of the accomplishments being highlighted were those of the Mayan and Aztec civilizations. Feeling that these topics may be over-researched, I decided to turn my attention towards the accomplishments of those in a different area of the world. After switching my focus to the pre-industrial astronomical feats of ancient Greek scientists, I have found that in many cases, these scientists contributed more than one idea, finding, or apparatus to the field of astronomy. For this research, I decided to hone in on the contributions made by Greek scientist Hipparchus. Throughout his magnificent life, and all before the implementation of modern technology,

“Therefore I would not have it unknown to Your Holiness, the only thing which induced me to look for another way of reckoning the movements of the heavenly bodies was that I knew that mathematicians by no means agree in their investigation thereof”. This had been what motivated Copernicus to discover the greatest finding of his time. Copernicus, Kepler, Galileo, and Newton went ahead and contradicted many theories that is well known in their time. Fear and uncertainty had kept some of them from letting others in on their new foundings. Afraid that their theories were going to be shut down and not accepted at all, as they would contradict many of the theories that had already been greatly accepted by everyone. In the scientific revolution the

Around the 50’s and 60’s, the United States and the Soviet Union had a “competition” called the Space Race. “They raced each other in achieving significant firsts in space”(Brigham). The Soviet Union beat the United States in the first satellite, first human in orbit, and the first space walk. But then, the United States stepped in with the first rendezvous in space, the first extension of mission durations in more than a week, and the first docking of space crafts. Later, the United states orbited the moon, and then the famous Apollo 11 mission was when Neil Armstrong and Buzz Aldrin first stepped foot on the moon.

Long ago, people began to observe the sky and astronomical objects to make predictions and modify calendars. Until early Ming Dynasty, China was way more developed in astronomy than that of European countries’. Gaocheng Astronomical Observatory was built in 1279 in China that enabled astronomers to calculate the accurate time of one year that was 300 years ahead of European scholars working it out (K.G 37). However, in the 18th century, Chinese star catalog was “relying on European data and the ephemerides were calculated on the basis of Newtonian theory” (Renn 283). Besides the failure to compute data

Edwin P. Hubble was born on November 20 1889 in Marshfield, Missouri. His parents were Virginia Lee James and John Powell Hubble who was an insurance executive. He had two sisters and two brothers. In 1900 his family moved to Wheaton, Illinois. As a kid, Edwin was a gifted athlete playing basketball, football, baseball, and was on the track and field team in which he won several awards. In 1906, he set the state high school record for the event High Jump in Illinois. Two of his favourite hobbies were fly fishing and boxing. 1907, he attended the University of Chicago where he studied math and astronomy and became a member of the Kappa Sigma fraternity. The same year, he led the University of Chicago’s basketball team to

Space race refers to the period from about 1957 to 1975, the United States and the Soviet Union to explore the field of competition in the development of satellites, manned space flight and the man on the moon and other space.

The Kepler telescope helps discover planets beyond our solar system. NASA launched Kepler in March 2009. The telescope, which is about 9 feet in diameter and 15.3 feet in height, now orbits the sun every 371 days. It observes 100,000 stars in a portion of our Milky Way galaxy to check whether the planets revolve around the stars. Kepler is explicitly looking for planets that could support life. For this, the worlds must meet two conditions: they should be small enough to sustain life, which is about the size of Earth, and they should be in the "habitable zone" of their stars. In the habitable zone, conditions on the planet, such as temperature, would be accurate for the presence of liquid water, and possibly life forms. When an orbiting planet

Nicholas Copernicus, a Polish astronomer, published a treatise, named On the Revolutions of the Heavenly Spheres, that countered Ptolemy’s theory. The Ptolemaic theory states that the a series of nine hollow and concentric perfect spheres revolved around a motionless earth in a perfectly circular path, with the first seven spheres having one of the heavenly bodies embedded in its shell, the eighth holding the stars and the ninth surrounding everything and providing cosmos’ spin that keeps everything moving. Beyond the spheres was heaven. On the other hand, Copernicus argued that the sun was in the center of the universe and the earth, along with the other planets, revolved around it. His theory implied that the earth was just another planet

What is a planet? While many people can point to a picture of Jupiter or Saturn and call it a "planet,"Planets change over time and can look different . Astronomers decided to have new definition in 2006 after the discovery of several worlds at the fringes of the solar system a decision that remains controversial. The term planet was from the Greek word for wonder. Ancient cultures adventured the stars. This is now called astronomy .But the study of earth is called geology . It was not until telescopes came out that we started to look at them in detail. There are nine planets all together. Telescopes also revealed the existence of objects not known to the ancients, because they are too far away and small to be spotted with the naked eye.

Why is the geocentric theory important and how does it affect us today? Before the Scientific Revolution, people believed that the Earth is in the center of the universe. There are many thoughts and ideas to this theory. Millions of people didn’t know that the theory is wrong. Not until Nicolai Copernicus discovered that the Earth is not in the center of the universe. Nicolai Copernicus helps us understand more about the solar system. He even drew a map of the solar system explaining how the Sun is in the center of the universe. During the Scientific Revolution there are many new ideas and inventions that we used today. One of the main idea is the geocentric theory, because how it affects us today is very important. The geocentric theory was

The creation of the Milky Way is a fascinating thing to learn about. Despite Immanuel’s thought on the Milky Way that wasn’t the only guess that other people made. In 1785, William Hurschel the discoverer of Uranus, decided to make a map of the shape of the Milky Way. The only problem that William did not discover was that most of this galaxy was made up of gas and dust which hid most of the galaxies shape. Because William Herschel failed to make the drawing it wasn’t until 1920 when scientists could get a somewhat close map of the Milky Way. It was until then Edwin Hubble figured out specific evidence that this spiral galaxy is actually made up from other galaxies combined (Universe Today, 2017). So now when people ask what is the Milky

Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, and astrological practices of pre-history: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy, and not completely disentangled from it until a few centuries ago in the Western World . In some cultures astronomical data was used for astrological prognostication.
