The article summarized below is from THE NATIONAL GEOGRAPHIC (issue Dec.97) by William R. Newcott. It tells about how comets are important and their effect on earth and its people.Comets are leftover scrubs of material that did not make it to planethood in the events creating our solar system. They orbit in a perpetual Deepfreeze until some subtle gravitational nudge upsets the delicate balance. The Great Falls begins. First a snowball drifts towards the sun and steadily accelerates. As solar radiation heats the comets the ice within sublimates, escaping as gas from vents from the surface. Sometimes jets of sublimating ice whirl off the rotating comet nucleus like a firework pinwheel. Dust trapped in the ice breaks free. Pushed back by the pressure of the sun’s radiation, the dust streams out behind the comet in what appears as a fairytale. The comet is among the fastest thing in the solar system.The most important new results are that the comet contains carbon compounds with trace of nitrogen sodium and sulfur. These ingredients are essential for life on earth. That is why scientist believes that a comet might have crushed on earth and from that moment life began. The ion tales are believed to be a kind of wind sock for the solar wind and NASA scientists are hoping to use it to get weather reports from distant solar system.Most comets can be only seen with a telescope but every once in a while an impressive one is visible to the naked eye. People through out history gave importance to comets. For example the Romans made a coin about a comet orbiting the sun that shows how its tail points away from the sun. The Babylonians recorded a comet sighting. One of the Astic leaders gave up his land to the Spanish upon seeing a comet.Definitely we are living in the age of comets where scientists detect it through telescopes and e-mail it to the central bureau for Astronomical Telegrams in Cambridge Massachusetts USA.
Not long ago on the 15th of February 2013 an asteroid named 2012 DA14 merely scrapped the earth’s surface by a tiny margin, even closer than some satellites. According to the NASA (National Aeronautics and Space Administration) the asteroid was 17,200 miles above our planet's surface, which may seem a long way from earth. However, in terms how big the earth is compared to the 17,200 miles, we can acknowledge that many people were saved from death.
Studying this comets might finally unlock some of the questions we have been asking for centuries like why are we here , are we just some random accident, what is our purpose. Most members of the scientific community and some outside of it believe in evolution the ideal that we evolved from single celled organisms in the ocean; some scientists believe that this water came with the necessary nutrients and minerals for evolutionary life to begin (Lauren, 2014). Sure there have been other mission in space many in fact landing on the moon, sending robot to versus to name a few, but I don't believe that they are going to have as much of an impact as this comet mission will. These are just a few things that make this mission so unique and important because is going to help use learn more about our selves, our world and the worlds around
Halley’s Comet or Comet Halley is a comet who orbits earth every 74.5 years! This comet is also the most known comet ever to be documented! Halley is very interesting comet.
The Birth of Venus is a beautiful Renaissance canvas masterpiece created by Sandro Botticello. The picture illustrates the birth of Venus in a very mystical way. Venus has emerged from sea on a shell which is being driven to shore by flying wind-gods. She is surrounded by beautiful roses which are painted in a truly remarkable color. As she is about to step to land, one of the Hours hands her a purple cloak. The back drop includes the sea and a forest. The overall effect of this painting are almost overwhelming, color and beauty meet the eye in every angle.
Nicolaus Copernicus was born on February 19th 1473 in Thorn, Poland (now known as Torun) to a merchant father who was also a local official. At the age of ten, Copernicus’ father died and he was sent to live with his uncle who at the time was a priest. In 1491, at the age of 18, Copernicus went to Krakow Academy as a pupil. In 1496, Copernicus then travelled to Italy and studied law at the University of Bologna. During his time at the University of Bologna, Copernicus lived with Domenico Maria de Novara, a mathematics professor who encouraged him to study geography and astronomy. Furthermore, throughout his time in Italy, Copernicus travelled to Rome and studied at the universities of Padua and Ferrara. Than in 1503, Copernicus moved back to Poland and worked for his uncle now the bishop of Ermland as a secretary. When his uncle died in 1512, Copernicus moved to Frauenberg and worked for the church. During his time working at the church, Copernicus studied astronomy and in 1514, when the catholic church was looking to improve the calendar, Copernicus was asked to help. Copernicus’ upbringing helped shape his interests in the sciences, especially astronomy. Copernicus is known to have established the heliocentric theory, which replaced the previously accepted geocentric model. However, prior to Copernicus other thinkers such as Aristarchus as well as thinkers after such as Galileo developed a similar theory. Even though it is unclear who established the heliocentric model, Copernicus has had a major impact on our modern sciences.
Scholarly Life in the 16th-century After reading On The Revolutions Of The Heavenly Spheres, Nicolaus Copernicus's dedication to Pope Paul III, it can be gathered that the life of a scholar was something of a mission, a crusade if you will, to achieve knowledge of the unknown. Like a crusade, scholarly life contained hardships but also achievements and even more importantly and sometimes most strived for, notoriety. Scholarly life in the 16th -century was no simple task, but a task that took much drive and ambition, and after that, a task that underwent much scrutiny from disapproving colleagues as well as outsiders.
A comet is categorized as an icy body that discharges gas or dust. Most comets that are visible from earth seem to travel in long ovals around the sun. Comets consist of a nucleus which is bounded by fuzzy or cloudy atmosphere and it might have a tail or two. The gases in the comet’s coma and tail are bright reflective so that allows us to see comets a lot better when they are closer to the sun. Astronomers also trust that comets release the energy they store from the sun causing them to glow.
The many minor members of the solar system are the asteroid and comet. The asteroid is a small, rocky body that orbits the Sun. A large number of these, varying greatly in size, can be found as an asteroid belt. There is an asteroid belt between the orbits of Mars and Jupiter. A comet is a small object made up of ice and dust, and when it's near the sun, it has a thin, fuzzy, temporary atmosphere. It also has a tail of gas and dust particles that faces away from the sun.
...ic records have shown that many mythological tales describe large scale natural disasters. It turns out that these legends may have been how ancient people described geological phenomenon that they did not fully understand. This can be seen is myth like that of A’yahos and Loki would cause earth quakes. This new research leads to new questions. How frequently are myths linked to geological phenomenon? How will these new finding change the way people view/value mythological stories? Linking myth to geological phenomenon will cause people to see myth as a record of past events. No longer will myth be classified as simple stories. They will hold direct knowledge of the real world.
A comet is composed primarily of ice and rock. Comets are thought to be remnants from the formation of the solar system, which occurred over four-and-a-half billion years ago. Comets have three main parts: the nucleus, the coma, and the tail. The main part of the comet, where the majority of its mass is located, is the nucleus. Like stated earlier, the comet is composed of ice, rock, and dust particles, all of which are located in the nucleus. This is actually the only “natural” part of the comet; it is the only part of the comet that is not formed from the effects of external forces. The coma of the comet is located around the nucleus. It is formed from melted ice and rock and dust sediment. The tail of the comet is also composed of these materials, but, unlike the nucleus and the coma, and as the name suggests, it is located behind the two other structures. These structures make up the entirety of the comet as we view them. The coma and the tail are formed from the effect of gravity and solar radiation. Solar radiation causes the ice to melt, so as to form the two structures, and gravity conforms them into the shapes that we observe in the night sky. These two fac...
Nicolas Copernicus died never knowing what a revolution he made in the scientific world. Mathematicians and scientist like Ptolemy, Newton, and Brahe supported his heliocentric theory. He was born in Poland on February 19th, 1473 the baby of four children. His father was Nicholas Copernicus Sr. died in 1483 when Copernicus was at the young age of ten. He and his sibling went to live with his Uncle Lucas Waltzenrode the bishop of Warmia in Germany. His family’s exceptional wealth allowed him to attend some of the finest schools in Europe. After attending Cracow for mathematics he went to Italy to study canon law. Under the influence of his uncle he become a canon, which is just below a bishop. In Italy he made his first astronomical observation one night with a friend who was a professor of astronomy. Copernicus explored many occupations: a canon, mathematician, and the one he is most known for astronomer.
“At 12:42 p.m. the air was perfectly calm for about one minute; the next minute the sky was completely overcast by heavy black clouds which, for a few minutes previous, had hung along the western and northwestern horizon, and the wind veered to the west and blew with such violence as to render the position of the observer on the roof unsafe. The air was immediately filled with snow as fine as sifted flour” (Potter). No one expected the blizzard that would soon come rolling over to create some of the unfortunate deaths. Now, the questions are what exactly happened during the storm, how are snowstorms created, and what damages it caused.
Copernicus was a Polish astronomer born in 1473, in Thorn, Poland and died in 1543. He entered the University of Krakow in 1491 and studied there for four years. In 1496 he joined the University of Bologna in Italy to study church law and studied astronomy on his own time. He was asked to make a new calendar using the geocentric theory, the theory that the sun and moon orbit the earth. He found several flaws with this system and was bothered by it and went on to discover that the planets actually orbit the sun. Galileo supported Copernicus’ theory when he made discoveries with the telescope. We consider Copernicus to be the founder of modern Astronomy.
Adam de la Halle was of French origins. All of his lyrics were written in French.
