In fact, one radical proposal: As far as the as the level of intricacies in this research is concerned one can surely acknowledge the capacity of work done but being stuck to it completely and researching on it again and again may sound an unreasoning thing to follow. Astronomers being addicted to their work styles, research requirements and updated developments or shooting of newest things in the world of sky have to be in touch with all these researches.

Also known as "failed stars," brown dwarfs are dim and rarely host solar systems. Because of their relatively small mass they cannot ignite and produce star light. However, brown dwarfs are also known as "super planets" because they often exist alone in space and are larger than most known planets.

The content of the article relates to many interrelated areas of cosmology and astronomy. First, the news clarifies the definition of brown dwarfs, of which relatively little is known because they are rare and dim. Also, if a brown dwarf can host a satellite planet then miniature solar systems could exist throughout space. The discovery also teaches fundamental concepts of astronomy such…… [Read More]. Metric System -- One of the Reasons. Metric ystem -- One of the reasons measurement can be complicated is that there is more than one system in use.

Based on the Ancient Roman system, the metric system is based on powers of 10; which is called decimalization. The metric system has been the preferred European and scientific method of measuring sine the 18th century, but is not part of the International ystem of Units, which is also standardized.

Because the metric system is based on powers of 10, units are easier to align. If Mike needed a desk that was 5 feet by 4 feet wide, how many inches of trim would he need for the whole desk. Johannes Kepler Was a Key. Had this false belief not been perpetuated it may very well be Kepler who directly formulated the laws of gravity well before the time of Newton. In his understanding and derivation of mathematical models to understand this process, Kepler noted that planets moves fastest when it is closest to the sun and slowest when it is furthest from the sun.

Again, this observation viewed through contemporary lenses makes the connection between the "hidden forces" of gravity as the evident driver, but Kepler concluded otherwise.

He noted that if a line were drawn from the center of the planet to the center of the sun, such a line would sweep out the same area in equal period of time. His explanation for the…… [Read More]. Small Pieces of Glass The. The Ptolemaic model was accepted by most philosophers of note until it was radically challenged by the Polish astronomer Copernicus in The Catholic church condemned the Copernican System in and forbade holding, defending, or even teaching alternatives to the Ptolemaic conception of the universe endorsed by the Church Fowler But both theories were mere conjecture until the development of the Galilean telescope.

Galileo did not invent corrective lenses or even the telescope, but he did substantially improve them. By making use of both convex and concave lenses, Galileo was able to expand the magnification power and distance vision of ordinary gazers, enabling to look wide into the heavens Fowler Chemical Properties of the Universe Astronomers Hypothesize.

Chemical Properties of the Universe Astronomers hypothesize that about 5 million years ago, the Solar System was filled with a plethora of hot gases and dust, swirling around a hot core. They think that once the core approached about 1 million degrees, the physics and chemical properties caused the gases to coalesce, forming the sun. During this time, there were millions and millions of asteroids. As these asteroids collided with one other, some combined and as their mass increased, gravity pulled more and more particles and debris in, and the planetoids became larger and larger until the planets of the solar system were formed.

This was a process known as accreation, and over hundreds of millions of years, the solar system formed -- the continual bombarding of asteroids changing the planets, forming the rings of Saturn, and the landscapes of others, including the moons -- which were just smaller planetoids…… [Read More].

Scientific Discoveries That Changed the. This new calculation proved bodies of mass could orbit the sun in an elliptic pattern. Newton also put a name and a definition to gravity.

His theories opened doors to understanding motion, matter, and space. Many of these theories are still taught today because they "still adequately account for most problems of motion" Noble People had to once again let go of familiar thought and embrace new ideas.

Newton transformed astronomy because he set "modern physics on its feet by deriving laws showing how objects move on the Earth and in space" Pasachoff These laws are the groundwork for what eventually led to the law of gravity. Newton was open-minded enough to understand that gravity was not something confined to this earth. It was universal and it applied to all objects in space.

The same…… [Read More]. Jocelyn Bell Burnell Was Born. It was a discovery that opened our eyes to the vastness of the universe and all that we do not know about it. First, "it was an incredible discovery for astronomers. It not only confirmed the existence of the theoretical neutron star, but it also enabled scientists to make advances in astrophysics, particularly in their theories of stellar collapse and the formation of black holes" Ruskin.

Ruskin admits, "Perhaps more surprising than the fact that a new type of star was discovered was that a woman had discovered it" Ruskin. Our planetary speck in space, namely the Earth, is only one of hundreds of billions of planets that surely orbit other star systems; our Milky Way galaxy, composed of billions of stars and other astronomical bodies, is but one out of billions of other galaxies.

Thus, in order to increase our knowledge of the universe, the Hubble Space Telescope serves a vital function, for since its launch in , despite several crucial problems, it has revealed a universe full of mysterious bodies, nebula, star systems and galaxies and has expanded the possibilities that humankind is not alone in the universe.

Mercantilism This Term Refers to. In its most basic sense, this treaty abolished the age-old practice of electing a king of the Romans, a reference to the Holy Roman Empire; it gave France the geographical areas of Verdun, Alsace, Metz and a portion of Strasburg; Sweden was given West Pomerania, Stettin, Wismar and Bremen, known as bishoprics but now part of northern Germany; Bavaria retained the Upper Palatinate and all electoral titles, and Saxony retained Lusatia.

Also, Spain was forced to fully recognize the United Provinces as a sovereign nation-state. Overall, the Treaty of Westphalia turned Europe into a conglomerate of separate political and economic nation-states that were only partially dependent on each other; the treaty also made it possible for mercantilism to spread throughout Europe, thus creating the foundation for many more years of conflict and war.

Planet Venus Venus A Planet. The discrepancies between the two solar systems has largely to do with the planet Venus. The theory claims that when the big bang occurred, matter, energy, space and time were all formed, and that the universe at that time was extremely hot and incredibly dense. Presently all the best minds in science have no idea what came before the Big Bang Theory. They have no answer. Stellar Evolution and Hydrostatic Equilibrium.

A dead star or black dwarf would be converted to interstellar matter spread out in space, and would eventually form a new star. This equilibrium process is made possible through thermonuclear reactions, wherein remaining hydrogen atoms are formed together to create a helium nucleus. Thus, through this process of death and eventual birth of a new star through stellar evolution, equilibrium was conducted and achieved.

Another equilibrium process that stars undergo is through the concept of hydrostatic equilibrium. This process is characterized as the balance between thermal pressure, which is directed outward, and the weight of the material above pressing downward -- that is, directed inwardly.

Hydrostatic equilibrium illustrates the presence of forces within a star: It also demonstrates how stars exhibit the…… [Read More]. Large Scale Features of This. The materials that are collected in them are solids from the various gases which cooled inside these clouds.

The gravity from the sun pulled them closer towards each other. This contributed to the formation of the planets and asteroids. This forms the Kuiper Belt and Oort Clouds, which is where the smaller debris is collected near the orbit of the outer body planets. These are the remains of the rubble that was used to create the solar system billions of years ago. However, there is an exception to this pattern. In research that was conducted on distant galaxies, scientists discovered that there are not large outer planets with asteroid belts i.

This led to theories that much warmer Jupiter like bodies could exist closer to these…… [Read More]. Twin Stars Twins - Typically a word indicating the production of two offspring from the same source of origin, mostly referred during reproductive results.

Department of Energy, and initiated through the grant from the Kavli Foundation. Cosmology the Formation and Evolution of Galaxies. Cosmology The Formation and Evolution of Galaxies One of the greatest and possibly most important questions about our universe is how it originated.

Galaxies come in three main types: The Galaxies There are a number of theories about the formation of galaxies. Two predominant theories are the ottom-Up and Top-Down theories. The ottom-Up theory states that the Universe started from small particles of mass that came together to form galaxies, which evolved into clusters and then super-clusters.

There are already several telescopes at the top of Mauna Kea, which at 14, feet is often above the clouds, in the middle of the Pacific Ocean with minimal light pollution. The telescope will be of the itchey-Chretien type, which is a Cassegrain telescope that has a hyperbolic primary mirror and hyperbolic secondary mirror. This is the most common type of telescope used in professional astronomy.

The TMT will also feature optical and infrared observing, "with wavelengths of interest ranging from nanometers in the ultraviolet to 28 microns in the infrared. The telescope is comprised of a large number of different systems within the same facility, including mechanical assemblies, control systems and distribution systems.

The actual summit enclosure…… [Read More]. Optical Revolutions How the Telescope. The universe viewed through a telescope looked different, and this difference in itself played into the Protestant argument that received truths may be fallible. In fact, the notion of truth outside empirical evidence became unsteady: Gone forever was the concept that the earth has a fixed spot in the center of the universe, for it was now conceived to be in motion…gone also was the comforting thought that the earth is unique Cohen 79 However, while the telescope was transforming ideas about the shape of the cosmos and the relationship between science and faith, the microscope essentially remained a toy through much of the early modern era.

If anything, the revelation of the…… [Read More]. English System of Measurement Is. Assignment -- a- Radiation may be considered information from space; different types of information from different sources.

Part B- Light may be measured by telescopes; other space radiation by radio waves; x-ray machines may absorb cosmic and x-ray energy. Measuring radiation from objects tells us numerous things; age of object, comparative data between object, distance, intensity, level of danger, potential changes within object over time. Part D- Spectrographs, radio frequency detectors, x-ray machines.

Part a -- an atom is the smallest unit of matter; ions are types of atoms in which the protons and electrons parts of the atomic structure are not equal. Ions can exist independently in solution, while atoms may or…… [Read More]. Advances in Telescopes in Recent. Science teachers can utilize this article by updating their curriculum related to the universe. While textbooks currently being used convey the traditional notions of the past, newer developments need to be incorporated immediately.

Most current aspects of science seem to change rapidly. Astronomers such as Fabio Governato from the University of Washington have demonstrated how supercomputers can be used to replicate the activities in space, which are invisible to our telescopes.

Using the components of the article to make a presentation on the latest developments in the field of space and technology can be a good approach. While most students would consider this just like any other class, it might stand out to some intelligent ones who could build a career in this area.

Science teachers can observe this article from a broader point-of-view, search for similar articles and satisfy their personal research interests.

That does not make them true, only possible Kraus, ; Cavelos, ; 4 Conspiracy theories abound in numerous genres and surrounding numerous events. While positive in tone, it also appears that if one believes conspiracy theories, most of us have only weeks to live; or simply turn the calendar to a new page?

The Science of Star Wars. Big Bang and the Evolution. At almost an hour after the Big Bang, all nuclear material has bonded, yet the temperatures is "still too high for protons and electrons to bind together" to form atoms. From this point on to about , years later, the temperature has dropped sufficiently and allows electrons and protons to bind together to create atoms of hydrogen. Therefore, as free electrons "are bound up in atoms, the primary cross-section leading to the scattering of photons is removed" which allows the universe to alter from being opaque to transparent, thus allowing photons of light to travel freely in this newly-created universe "The Hot Big Bang" , Internet.

At some unknown point in spatial time, the universe begins to cool even further, allowing gases like…… [Read More]. Challenger Space Shuttle Disaster it. There was one thing or the other to delay the launch of the Challenger, until the D-Day, when the shuttle was launched at About seventy three seconds into the mission, the Challenger exploded in mid air, and all the seven crew members were killed instantaneously. For the hundreds of people, the family and friends and others who had gathered at the site to watch the launching of the Challenger, it was a sight that they would never be able to forget.

They were forced to watch helplessly and fearfully, as the fiery flames consumed their loved ones. The entire nation, which was watching events as they unfolded on their television sets, was rendered speechless. Physics - Mission to Mars. The Mars exploration program announced by President Bush in relies on first establishing a prolonged human presence on the Moon, in conjunction with completion of the International Space Station by The President envisions returning to the Moon by at the latest, for the purpose of being able to launch robotic missions to Mars Whitehouse, This is a view with which I am inclined to agree.

Science Fiction to Science Fact. London American Physical Society. Pluto Why Is Pluto No. Even some scientists who disliked the definition, however, felt that it was fair to demote Pluto. In addition, a planet has to dominate the neighborhood around its orbit," and Pluto is not simply small, and Pluto also does not dominate its neighborhood but its moon Charon, is very large in proportion to the former planet, as is about half the size of Pluto, "while all the true planets are far larger than their moons" Inman, "In addition, bodies that dominate their neighborhoods, sweep up asteroids, comets, and other debris, clearing…… [Read More].

Evolution and the Big Bang. This is believed to be the remnant that scientists were looking for. Penzias and Wilson shared the Nobel Prize for Physics for this discovery.

Finally, the abundance of the "light elements" hydrogen and helium found in the observable universe are believed to support the ig ang model of origins the ig-ang Theory Web site, In , Physicist Robert Gentry proposed an alternative to the standard ig ang theory, an alternative that also accounts for the evidences listed above Eastman and Missler, Gentry believes that the standard ig ang model is founded upon a faulty paradigm that he claims is inconsistent with the empirical data.

Other high-profile dissenters include…… [Read More]. Big Bang Theory Is a. The singularity at the beginning of the Big Bang did not begin in space; it was the origin of space. Black Holes hile singularities are difficult to define and to prove, black holes are not.

Black holes are areas with such extreme gravitational pull that the velocity an object would need to escape them is greater than the speed of light, and, thus, unattainable. They may be created when a star collapses, though this is also a theory.

Infinite Density Because the gravitational pull of a black hole is immense, objects cannot escape from it. Moreover, as the objects approach the event horizon of the black hole, the gravity becomes more and more intense, so that, eventually objects are unable to escape. This means that the black hole continues to engulf matter.

Furthermore, the intense gravity that exists in a…… [Read More]. Copernican revolution has a pivotal role in the establishment of the modern sciences. We are very much familiar with the fact that the human mind had always been fascinated greatly by the changes taking place around him almost constantly. Human observation and sense of argument and ability to be logical has made him the most intelligent and consequently most powerful species on the planet.

It is very comfortable to believe that Earth is located at the centre of the universe and other planets rotate around it because Earth itself does not seem or feel to be moving and there are only sun, moon and other planets appearing and disappearing at their exact timings.

It is quite logical and unless and until something really revolutionary come forward to refute this believe, it looks quite reasonable to carry on believing the same idea Kuhn, pp Nicholas Copernicus The most significant change…… [Read More]. Eternal Circle of Time Electrons Circle the. Eternal Circle of Time Electrons circle the nucleus of an atom. Untold trillions of atoms collide together and explode. Electrons race down the copper wires of an electric cable.

Leaves digest the sunlight, produce nutrients, live, grow, die, and fall to the ground. The wind bears aloft the leaves, scatters them over earth and sea.

The tide moves them, pushes them up into rivers where at last they settle into the mud. Salmon swim upstream; lay their eggs on the muddy bottoms of lakes and rivers. A powerful grizzly bear nuzzles the icy water of a mountain brook. His great paw sweeps into the water and catches a darting salmon. Men come; establish a city on the banks of the stream.

They drive the bear off. Their boats coast upon the surface of the sparkling water. Nets plumb the frigid depths, resurface filled with…… [Read More]. Computers in Space Science. Specifically, it will look at the roles computers have in current space technology and how they have effected the lives of everyone in the world. Computers have made it possible to explore the moon, stars, and beyond. Computers in Space Science Computers play an integral role in the science of space, and without them most of modern space exploration would not be possible.

NASA employs literally thousands of computers throughout the world to monitor, design, and…… [Read More]. Capturing Astronomical Geometry the Greek Way. Alexander was so smitten with Adrianna that he promised her the moon. Alexander had long heard the stories about his Greek ancestors who were experts in mathematics and astronomy, so he sought out some wise elders to learn more. Alexander spent some time with two elders, one of whom told him he knew how to measure the size of the earth which, Alexander mused, was bound to impress, Adrianna ,…… [Read More].

Galactic Center in Infrared. Galactic Photo This image is of the galactic center, which is the center of the Milky Way. The photograph is taken using infrared light, which changes the appearance of dust particles so that they do not obscure the image. As Wright points out, the universe is filled with dust, which tends to block the light being emitted from light-giving objects like stars.

The composition of most galactic dust includes carbon, silicon, and oxygen Wright, Infrared allows the exposure of rays that are beyond what the naked eye can see. These rays are beyond or below the red part of the color spectrum, which is why the technology is called "infrared. Although not visible to the human…… [Read More]. Johannes Kepler Made Important Contributions. Solar heat is trapped by certain gases including carbon dioxide and methane.

These gases allow sunlight in but not back out of the atmosphere. This effect can be seen on a small scale when a car parked in the sun with its windows closed heats up. It has been set in motion by the greenhouse effect but is more complicated because there are feedback effects involved in climate change that magnify the initial effect of the build-up of gases such as carbon dioxide.

Global warming has the capacity -- indeed, probably the inevitable capacity -- of transforming nearly every aspect of our lives, and in most ways for the worse Solomon etal, , p. Question Four…… [Read More]. Before we into depth about mirages, its imperative to understand the concept of what mirages is. So, what exactly is a mirage? First of all, one thing is for sure, mirages are certainly not optical illusions, as many people believe.

They are real phenomena of atmospheric optics, formed by strong ray bending in layers with steep thermal gradients. Mirages can be captured in real photographs because they are real physical phenomena. What should be understood is that distorted images produced by mirages may produce optical illusions, but what is false is when an observer confuses the observation with the distinctly different classes of these unique phenomena.

A mirage…… [Read More]. AZTECS The ancient Mexican region not only stands out as a mythological haven, but also as a culturally vibrant and technologically advanced civilization. Among the Mesoamerican civilizations, the Aztecs standout for their significant contributions in the fields of astronomy, medicine, and also for their bizarre ritualistic practices. The Aztecs represent an important group of the Mesoamerican civilizations.

Initially, confronted by the Culhuacans the Tenochcas had to flee the mainland and move towards the island. Under the command of Itzacoatl, the Tenochcas gained freedom and undertook the construction of the grand city of Tenochtitlan. As new regions in the valley of Mexico came under the Aztecs they also absorbed the…… [Read More]. Eudoxus of Cnidus Boyer in. He invented a planetary system, which consisted of spheres, the earth being still at the center, and twenty-seven concentric spheres rotating around the earth.

Actually, most of his accomplishments are difficult to explain at all to the nonprofessional, since they involve the complicated fields of math and astronomy. However, what his work does is make the work today so much easier. Those who labor in those fields know the practicalities, complexities, and almost impossibility of what Eudoxus did. Eudoxus made important contributions to the theory of proportion, where he made a definition allowing possibly irrational lengths to be compared in a similar way to the method of cross multiplying used today.

A major difficulty had arisen in mathematics by the time of Eudoxus, namely the fact that certain lengths were not comparable. The theory developed by Eudoxus is…… [Read More]. Q 1 What Is the Accurate. The collapse increases internal pressure until some of the stars external matter is ejected, eventually stabilizing into a dwarf star of degenerate matter.

A variable star is one whose apparent brightness changes as viewed from earth. Cepheid variables are a certain type of variable star whose apparent brightness changes in regular cycles lasting from 3 to 50 days. Astronomers use them to measure distances in space.

What happens when the star shrinks to the radii? The Hertzsprung-Russell diagram is a scatter-graph of stars that allows astronomers to plot their absolute luminosity against their specific classifications and temperatures.

This technique demonstrated…… [Read More]. Once complete, left final paper. The Scientific Revolution represents development thinking world. Attitudes during the Scientific Revolution The scientific revolution and the age of classical science have had a severe impact on society and made it possible for it to experience great progress as a consequence of the fact that technology had advanced significantly.

Humanity was especially ignorant up to this point and technology actually made it possible for the masses to look at the world from a different perspective. People learnt that a lot of things they previously believed to be impossible were actually possible and joined the rest of the world in a struggle to achieve progress. The Scientific Revolution basically represents the moment when the social order started to experience massive reform as a result of technological advancements.
