  • Aurora Borealis - 1,720 words
    Aurora Borealis AURORA BOREALIS Imagine a cold October night, you walk out to your car and something catches your eye. You step further into the street be it busy or not, and you begin to turn in 360 circles. For what your eyes behold is far from anything you have ever seen. A circle of green and blue swirl through the night sky, I could best describe this as two ballroom dancers doing a Waltz through the night sky. They flow, they glide so gracefully that they capture you and keep you entranced for a very long time. This my first experience viewing the amazing Aurora Borealis, it did not matter that people were watching, or that the roads were iced over and that I could not stand on ...

  • Comets - 1,438 words
    Comets Before the seventeenth century, comets were considered portents-warning shots fired at a sinful Earth from the right hand of an avenging God. However, in the post-Newtonian era, when their paths were understood to intersect that of the Earth, they were considered actual agents of destruction. Experts have described comets as the carriers of both life-seeds to the early Earth and horrific missiles that will one day snuff out life as we know it. At one time or another, people have blamed comets for war and held responsible for the deaths of men, the birth of good wine, the London fire of 1666, severely cold weather, etc . . . If one central theme runs throughout history of comets, it mu ...

    Comets The first written records of comets date back to nearly 3,000 years ago from China and Europe. The accounts of these comets were believed to be the causes of terrible events that occurred afterwards. In more recent times, however, astronomers have found out what they really are. A comet is basically a mixture of ices, from both water and frozen gases, and dust. They have also been given the names dirty snowballs or icy mud balls. The typical comet is less than 10 kilometers across. They spend most of their time frozen solid in the outer parts of our solar system. Comets are composed of five parts: the nucleus, coma, hydrogen cloud, dust tail, and ion tail. The nucleus is pretty solid ...

    ... is cloud remains a theory only, as it has never been directly detected. The Kuiper Belt is a region that was first proposed by the Dutch-American astronomer Gerard Kuiper in 1951. Seeing that Oort's cloud of comets did not really explain the reason for the population of comets with short orbital periods (making complete orbits around the sun in less than 200 years), Kuiper thought that a belt of comets probably existed outside the orbit of Neptune within the range of 30 to 50 astronomical units (2.8 to 4.6 billion miles) from the sun. Collisions and perturbations by the planets of our solar system are believed to be the reasons for the ejection of bodies from this belt. Around 1988, astr ...

  • Earth Planet - 2,166 words
    Earth Planet The Earth, man's home, is a planet. The Earth has special characteristics, and these are important to man. It is the only planet known to have the right temperature and the right atmosphere to support the kind of environments and natural resources in which plants and man and other animals can survive. This fact is so important to man that he has developed a special science called ecology, which deals with the dependence of all living things will continue to survive on the planet. Many millions of kinds of plants and animals have developed on Earth. They range in size from microscopic plant and animals to giant trees and mammoth whales. Distinct types of plants or animals may be ...

    ... salt dissolved in the oceans is, on the average, 34.5 percent by weight. About the same percentage can be obtained if three quarters of a teaspoon of salt is dissolved in eight ounces of water. Water Supply for the Earth Water that evaporates from the surface of the oceans into the atmosphere provides most of the rain that falls on the continents. Steadily moving air currents in the Earth's atmosphere carry the moist air inland. When the air cools, the vapour condenses to form water droplets. These are seen most commonly as clouds. Often the droplets come together to form raindrops. If the atmosphere is cold enough, snowflakes form instead of raindrops. In either case, water that has tr ...

Block Is were the initial R and D birds and a few (four or five) are still ope! rating. They're smaller than the Block II production satellites and don't have the same amount of military spook stuff aboard. They're also not selective-availability equipped. The full constellation of GPS satellites is due to be in orbit by mid-1993, if all goes according to plan. (No guarantee there). Until then, the system is deemed by the Defense Department to be under construction. THE BOYS IN BLUE The U.S. Air For ...

  • Oceanography From Space - 1,181 words
    Oceanography From Space At first thought, studying the oceans from space seems to be a bizarre idea. Space observation helps oceanographers do research with manned and unmanned space systems. The space systems can be satellites and/or space shuttles that observe various features of the ocean such as sea-surface winds, sea-surface temperatures, waves, ocean currents, frontal regions, and sea color. Technological advances have greatly improved the ability of oceanographers to gather and use information that is received. Oceanography as viewed from space has and will become more and more valuable as we begin to understand more of the world's oceans. Projects Space oceanography uses a number of ...

  • Origin Of The Solar System - 886 words
    Origin Of The Solar System For more than 300 years there has been serious scientific discussion of the processes and events that led to the formation of the solar system. For most of this time lack of knowledge about the physical conditions in the solar system prevented a rigorous approach to the problem. Explanations were especially sought for the regularity in the directions of rotation and orbit of objects in the solar system, the slow rotation of the Sun, and the Titius-Bode law, which states that the radii of the planetary orbits increase in a regular fashion throughout the solar system. In a similar fashion, the radii of the orbits of the regular satellites of Jupiter, Saturn, and Uran ...

  • Our Solar System, The Sun And Its Planets Has Not Always Been There - 459 words
    Our Solar system, the sun and its planets has not always been there. It is nearly five billion years ago, and there is no solar system, no planets, moons, no sun. Instead there is a big cloud of dust and gas called a nebula. This cloud has been slowly twisting for more than 10 billion years, held together by its own gravity. Then a star explodes......WOW!! its a super nova.... The blast pushes the gases of our nebula together. That strengthens the gravitational pull of those gases even more and they begin to come together still more. The whole cloud begins to get smaller and as it does so, it swirls faster and faster, and grows smaller and smaller. Ok, dudes and dudettes, lets take a closer ...

  • Over The Past Years Most Individuals Have Become Acutely Aware That The Intensity Of Human And Economic Development Enjoyed O - 2,093 words
    Over the past years most individuals have become acutely aware that the intensity of human and economic development enjoyed over the 20th century cannot be sustained. Material consumption and ever increasing populations are already stressing the earths ecosystems. How much more the earth can take remains a very heated issue. Here a look at the facts sheds some very dark light. In 1950, there were 2.5 billion people, while today there are 5.8 billion. There may well be 10 billion people on earth before the middle of the next century. Even more significant, on an ecological level, is the rise in per capita energy and material consumption which, in the last 40 years, has soared faster than the ...

  • Saturn - 1,391 words
    Saturn Saturn Saturn is one of the most interesting planets in the solar system. It is the sixth planet in the solar system, and is most famous for its stunning array of rings. It is a very easy planet to pick out in the sky because it is one of the brightest lights in the shy. It also has a very faint greenish color that makes it stand out from the rest of the objects in the sky (Astronomy for Kids). Saturn is the second largest planet in the solar system, Jupiter being the only planet that is bigger. It also has at least eighteen moons, more than any other planet in the solar system. There have been three voyages to this extraordinary planet, and one is still in process today. The Pioneer ...

    ... Saturn, has been a major process in shaping the solar system. Mimas is marked by a huge impact crater called Herschel that is fully one-fourth the diameter of Mimas itself. This crater makes Mimas look like a staring eyeball, giving it the nickname Death Star. The impact that formed it was almost intense enough to blast Mimas into fragments. This moon is the innermost of Saturns large moons, orbiting outside the rings of its parent planet. Herschek is 140 kilometers (90 miles) across and 10 kilometers (6 miles) deep. It is one of the largest craters, with respect to planetary diameter, in the solar system (Great Space Place). Enceladus, another of Saturns moons, is located in the center ...

  • Sources Of Energy - 1,387 words
    Sources Of Energy Sources of Energy Have you ever thought about how we get the energy to run the things we take for granite every single day. There are many sources of energy that that are used for transportation, heat, light, and the manufacturing of goods of all kinds. The development of science and civilization is closely linked to the availability of energy in useful forms. The seven main energy sources are fossil fuels, hydroelectric, solar power, win power, geothermal, nuclear power, and biomass energy. By harnessing the sun, wind, falling water, plant matter, and heat from the earth, energy planners expect to decrease the environmental impact on energy use. Most of the nonhydro renewa ...

    ... temperature and contaminant-free environments. Solar cooling can be achieved through the use of solar energy as a heat source in an absorption cooling cycle. Solar power research is being pursued in connection with efforts to design residential and commercial buildings that will use energy more efficiently. Some other promising devices are solar collectors and solar mirrors. Solar energy is a very expensive process that take years to develop the technology for it. This energy can only be used in the daylight ( when the sun is out ), so during the night you wouldn't have energy then. Another important source of energy is wind power. The most popular device is a mechanical device that harn ...

Mass More than half of all stars are BINARY STARS--two or more stars that orbit one another. About 100 orbits have been measured accurately. These measurements provide perhaps the most important characteristic of a star: its mass. From Newton's Laws of gravitation and motion, it is known that two highly massive stars must orbit (one around the other) faster than two stars of lesser mass at the same distance apart; thus the masses can be calculated from the orbit size and the period of the orbit.

  • The Moon - 1,390 words
    The Moon The Moon is the only natural satellite of Earth: orbit: 384,400 km from Earth diameter: 3476 km mass: 7.35e22 kg Called Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies. The Moon, of course, has been known since prehistoric times. It is the second brightest object in the sky after the Sun. As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moon's phases. The time between successive new moons is 29.5 days (709 hours), slightly different from the Moon's orbital period (measured against the stars) since the Earth moves a significant distance in its ...

  • The Solar System - 1,185 words
    The Solar System The Solar System consists of the Sun, the nine planets and their satellites; the comets, asteroids, meteoroids, and interplanetary dust and gas. It is composed of two systems, the inner solar system and the outer solar system. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. The outer solar system contains Jupiter, Saturn, Uranus, Neptune and Pluto. The inner planets are relatively small and made primarily of rock and iron. The asteroids orbit the sun in a belt beyond the orbit of Mars, tumbling and sometimes colliding with one another. Made mostly of rock and iron, the asteroids may be the remnants of a planet that never formed. The outer planets, wi ...
