Saturn is the second largest planet and sixth number planet of our solar system. Saturn is a gas giant made up of hydrogen and helium. It is big enough to hold more than 760 Earths within it, and is second massive planet after Jupiter, roughly 95 times Earth 's mass. However, Saturn has the lowest density among all the planets of solar system .It spins faster than any other planet except Jupiter which help Saturn with its magnetic field which is about 578 times more powerful than Earth 's. Although Saturn has at least 62 moons but its largest moon, Titan, is slightly bigger than Mercury, and is the second-largest moon in the solar system after Jupiter 's moon Ganymede (our moon is fifth largest).Although it is the most interesting planet
This military fort is in Newcastle 130 miles west of Dallas/Fort Worth. During the territorial annexation of Texas this fort protected settlers against the local Comanche and Kiowa Indian tribes who were raiding the land. There is a mini museum about the fort with original buildings, cannons, and guns. Now, it 's a historical landmark and state park with a cemetery and graves for the people who died. Also, the Texas Ranger used this fort to fight their battles.
Humans have been dreaming about space travel since antiquity. The Chinese used rockets for ceremonies and military purposes centuries ago, but only in the final years of the 20th century were rockets manufactured that were powerful enough to outstand the force of gravity to reach orbital velocities that could open space to human exploration. A lot of scientists have devoted their lives to revealing the secrets of space and finding the answers to questions related with human existence, space expeditions, the existence of other civilizations, and the structure of the universe. Fortunately enough, due to the developments of such sciences as physics, chemistry, astrology, mathematics and so on, scientists and engineers worked together and managed
William Herschel found Uranus on March 13, 1781. This was a big deal to him and his career. As stated in a document I found “Uranus was important for Herschel because its discovery was a passport to royal patronage, a pension of 200 pounds per annum, and a substantial support for his investigations of the construction of the sidereal heavens”. Herschel used a telescope which no one found would really work and the thought of one working was unimaginable. Some small ones were in use by scientist but Herschel wanted to develop a more powerful one that everyone would know would work better.
This spacecraft swung past Jupiter on February 2007 for a gravity boost before continuing on the rest of the venture of the mission that was intended for a flyby of the dwarf planet, Pluto. On July 14, 2015, New Horizons made the closest approach to Pluto, sending back many pictures of the planet. Now, as part of the extended mission (pending NASA approval), the spacecraft is expected to head further into the Kuiper Belt. If able to, New Horizons will be examining ancient, icy mini-worlds that are at least a billion miles outside of Neptune’s orbit.
Pluto, a planet that is only known to the average huan as the reject planet (once the ninth planet of our solar system,but now catorgized as a dwarf planet) and no thing else. So because of this lack of knowlegede scientist at NASA made a spacecraft named New Horizon to find anymore information on Pluto via flyby scan. After 9 and a half years hardship the spacecraft reached its destination. When the spacecraft sent information to the scientist on the dwarf planet scientist were dumbfounded on the output data. New discoveries were found on the once ninth planet and some don 't know what to do. All scientist do know is that Pluto is more than what meets the eye.
Musician and astronomer, William Herschel, changed the way we look at the sky in the 1780’s. In 1781, Herschel went on an adventure to construct a telescope with bigger reflecting mirrors than had ever been used before (Hoskin). He made a telescope that was top of the line for that time. He discovered Uranus, which was the first planet to be discovered in a very long time (Upgren). Many people inspired and aided Herschel’s desire to study astronomy. A professor at Cambridge, John Micheli, helped lead William’s quest as he sought to create a more advanced telescope (Hoskin). I feel like one of Herschel’s biggest helps would have to have been his sister and fellow astronomer, Caroline Herschel (Upgren). She would have been a great support to him as he sought to discover more about the world above us. It was hard for people to believe that he had discovered a new planet. In fact, the public was more willing to recognize Herschel’s discovery of double stars at first (Hoskin). I feel William Herschel helped motivate the astronomy world to continue to discover about the stars and the secrets of space.
I chose to do my research on “Astronomy: Discovery of Uranus by William Hershcel in 1781.” I used for my research Google Scholar and The David O. McKay Library. I found that William Hershcel was a musician and amateur astronomer. Hershcel was surveying the stars in March 1781, when he saw what appeared to him as a comet. (1) He really had no motivation to be looking at the stars other than he enjoyed the ability to use a reflective telescope to do so. Hershcel documented the movement of this comet but discovered it was moving too slow. After making some calculations, he realized he had discovered a new planet. On the website, Universe Today, it read about naming the planet, “Herschel’s original plan was to name this new planet after King
Below the turquoise waters of Mexico’s Yucatán Peninsula lies the site of a long ago mass murder. In a geologic instant, most of the world’s animal and plant species went extinct. Drilling through hundreds of meters of rock, investigators have finally reached the "footprint" left by the accused. That footprint marks Earth’s most notorious space rock impact.
William Hershel’s motivation was “piqued by two developments. One was his systematic examination of the clusters and nebulae catalogued by the French comet hunter, Charles Messier, in 1782 and 1783” (source A).Herschel built upon the work of this French astronomer and developed better telescopes that clarified and answered research and questions posed by Messier. Clearly Herschel’s motivation was to expound, rectify, and discover answers about the universe and give them to the world. He was also influenced by the surprising results his sister Caroline was able to conjure by studying the sky with a telescope William built for her. He believed that “if Caroline could find new objects with her small telescope, a larger instrument, deliberately designed to search the skies, would reveal many more” (source A). I find his motivation to be really pure scientific interest in learning more about the natural world.
The Scientific Revolution was the beginning of questioning tradition and the end to many unanswered questions. We’ve come a long way since Eratosthenes (276-194 BC) proved that the earth’s surface was round by measuring the shadows of two sticks near the city of Alexandria. Although Eratosthenes may
A star that goes by the name of Trappist 1 (named after the small telescope in Chile TRAnsiting Planets and PlanetesImals Small Telescope–South)has orbiting planets in the constellation Aquarius. Trappist 1 is about 40 light years away from Earth and is 12 times less the size of the sun but only a little bit bigger than Jupiter. Out of these seven planets, three of them are best suited for life. These planets are part of the Goldilocks Zone, they have the right amount of energy from their host star that oceans could exist. A group of astronomers found these planets by using a method called the transit method of planetary detection. These astronomers were focusing on finding evidence of planets around small dwarf stars, they observed the changing
Today virtually every child grows up learning that the Earth orbits the Sun, but four centuries ago the heliocentric solar system, where the Earth orbits the Sun, was so controversial that the Catholic Church classified it as a crime of heresy (UCLA). In the age of early philosophy, Socrates’ is well known. Between the Socratic method and his line of successful students, Socrates’ makes the history books. Galileo Galilei turned astronomers on their heads when he discovered moons around Jupiter. Giordano Bruno didn’t back down from any of his brilliant and different ideas. There are so many amazing and philosophical minds, their lives ruined all too soon, leaving minds to wonder, “What would have become of the world if these men could have had a couple more years of freedom?” From religious tyranny, to a constant debate about church vs state, and then the confusing world of astronomical debates, we are given many prime reasons for the persecution of philosophers.
