Extract of sample "Key Notions in Astronomy"

A new telescope specially designed to meet the needs of this problem can be helpful. This telescope should be equipped with the latest technology. It will target the ultraviolet wavelength of the electromagnetic spectrum. My grand telescope will roughly have a diameter of 450 in and a focal length of 660 in. The project will be very expensive and international support will be definitely required. Total expenses involving construction, transportation, and installation can surpass $160m.
If the greatest auroral storm or the largest solar flare to date hit the Earth on August 01, 2013 and I were to visit New York City that day, I would expect the sky all over to have a deep crimson hue. Everything around me would brighten up in the most brilliant and intense way due to the solar flare. All electrical and wireless systems will fail which will cause a lot of damage worth trillions of dollars. When power systems will shut down, the city will be badly affected as will my personal life. Everyone will have to survive without electricity and power of any kind. It will probably take me a long while to get back home.
Our sun is quite common in the universe and is not at all unique. It is basically a ball of plasma of average size. Trillions of other stars of the same size as the sun and even bigger than it are scattered around the universe. Stars also produce their own light, just like the sun produces its own light. This makes the sun very common. However, what makes the sun unique among other stars in the galaxy is the fact that the sun is closer to the earth than any other star in the galaxy. Also, no other star can compete with the temperature of the sun. Light from the sun reaches us within minutes, while light from other stars can take years to reach the earth.
Stars compose heavier elements from lighter elements by their fusion during their lives. These elements are then thrown out of stars into space and they form new stars. Humans have these heavier elements within them. Our earth and the remaining universe are also made out of these elements which came from stars. So, we are in a sense made up of star stuff. This means that our origin is related to elements heavier than hydrogen or helium. Those elements responsible for our origin and the world’s origin came from stars. Water in the human body would not be possible without these larger atoms because, without oxygen, hydrogen or helium alone could not have done anything.
During the sun’s transition when it will blow 100 times larger, the earth’s atmosphere will become deleteriously dry because all water vapors and water resources will become depleted. It will become very hard to live on this planet then because, with the sun’s transition, the earth will become a harsh, dried-out, and an unfriendly place to occupy. All terrestrial life on the earth will become extinct due to no water and inhospitable conditions. No other planets will be habitable as well and the earth will be pulled into the sun. Read More

...ASTRONOMY Since speed of light is approximately 3.00 km/s vast distances are easily covered. The present technology doesn’t have the liberty of traveling at speed of light. According to the scientific theories when traveling at the speed of light one can look back into the time. And it is practically proven too, the best example is the explosion of a star at a distant galaxy that might say some 10 light years. This means we are able to see the explosion after 10 light years. 2. When we move from north to south it can be observed that new constellations are arising above southern region. This is one of the reasons that we can say earth is spherical 3. “The law of universal gravitation states that gravitational force between masses decreases...

...1. What is the scientific view of astronomy? The scientific view of astronomy is when an individual tries or is taught about the planets, stars, and constellations. The focus of these studies are what make up these heavenly bodies, how they move, and more of the substance of the planets and stars. 2. a. what are constellation? What purpose did they serve to ancient civilizations? A constellation is a grouping of stars and planets that form patterns. In ancient civilizations constellations were used for astrology or myths. Astrology is where stars and planets are tracked in order to predict an individual or society’s future. Constellations like Orion, Mars, and Jupiter were mythical gods to ancient civilizations. b...

... by Atheists. No omniscient being could have created the Earth, because the scientific proof shows otherwise. Unlike the agnostic that does not believe because lack of evidence, Atheists believes no higher power ever existed. The astronomy findings and other science are often touted as proof of their beliefs. Intelligent Design is the new compromise that Christians, Islam, Judaism, and even Eastern religions have made about a higher power creating the universe. Basically an Intelligent Design example is of building blocks. When an individual take building blocks with the alphabet or numbers and throw them on the floor, rarely if any design can be determined. The universe is too complex for it to have left to chance. Evolution, according...

...Astronomy Questions Word Count: 500 (2 pages Answer the following questions regarding measurement and distance. 

 A. Why would the English system of units be more useful if a foot contained 10 inches? Use a math example and write out a clear reason. (75 words) The English system of units would be more useful if a foot contained 10 inches because then it would be comparable to the metric system, which is a base-10 system. Since the foot equals 12 inches, for example, one has to convert that to a ratio in order to figure out what one foot would be in centimeters. That is just one math example but there are several others which demonstrate this logical point easily. B. Why are some distances measured in light-years and some...

...ASTRONOMY ASTRONOMY THE SKY MODEL FROM THE SAME SPOT TO THE NEAREST INCH Source: Suhai, B.; Horváth, G. (2004).How well does the Rayleigh Sky Model describe the E-vector distribution of Skylight in clear and cloudy conditions. According to the Rayleigh sky model the daytime pattern of the sky is described in a polarized set up. The effect of Rayleigh scattering causes the light of the sky to have a definite pattern of polarization hence the blue color through the elastic scattering. This effect is mainly attributed to the scattering of light from water, aerosols, water and light from water molecules. At each wavelength the polarization is determined by the degree of polarization and orientation also known as the scattering angle...

... How can the Atlantic Ocean be getting bigger- What is causing it? How fast is this happening, and whenwill it stop (if ever) and how do we know this? There have been recent suggestions that the ocean floor of the Atlantic Ocean is spreading. The report indicates that the flour is spreading at a rate of five centimeters per annum. When the sea floor expands, it can cause all types of destruction on the various edges of the tectonic plate of the earth. The different havocs caused can cause earthquakes, coastal flooding as well as volcanic eruptions. One of the main reasons why the sea floor of the Atlantic Ocean is getting bigger is the bubbling up of the magma beneath the ocean. The seafloor of the Atlantic Ocean has numerous... How can the...

... Astronomy Question If the Earth shrunk to half the diameter, it is going to rotate at a high speed because of the principle of the angular momentum or motion. However, the orbit and the moon will not be affected since the gravitating bodies work as point masses at the center of the gravity, and that would not change. Moreover, the Earth’s heat would increase due to the increase of pressure and density that would eventually make the Earth a hard place to live and, therefore, all living organism would die. Furthermore, the surface of the Earth would reduce to quarter, and the ocean would be a lot deeper in fact covering the world. The gravity would decrease since as you come closer to the center of the earth there is the decrease... Astronomy ...
