Our Conceptualization Of The Solar System - 1,244 words
The human conceptualization of the solar system dates back to the beginning of time. The early Egyptians worshipped the sun as a source of life and then the area called space was becoming a curiosity to humans. Throughout history, our knowledge of the solar system has increased and there is still much to learn. Through the research and studies of Brahmagupta, Ptolemy, Kepler, Brahe, Copernicus, Galileo, Newton, and Einstein. With this knowledge, laws and equations for physical science have been developed and they have been useful to analyze many tangible aspects of science. The earliest astronomers were Ptolemy (90-168 AD) and Brahmagupta (590-678 AD). Ptolemy extended the observations and c ...

The Solar System - 1,175 words
Our understanding and our modern perception of our solar system, the Milky Way, has been drastically reshaped from the corresponding perception of only a few hundred years ago. Our Solar System, the Milky Way is probably about 4-5 billion years old. Only in the last 400 years or so have we realized that the earth is not the "center", and that in the Universe alone there is an immense 200 billion "Suns" in a galaxy like our own. Although the origin of the solar system is uncertain, most scientists believe that it began to develop about 4 1/2 billion years ago from a large cloud of gas and dust. The Sun is the largest celestial body in the Milky Way Solar System, with more than 1.000 times the ...

Liquid water cannot exist on Mars's surface because of the low temperature and pressure' water exists only as ice deposited at the poles and perhaps trapped below the surface and as vapor in the atmosphere. Mars is very desolate and barren and is covered in craters and are prone to violent sandstorms. The UV radiation of Mars would kill any known life. Mars has the largest volcano in the solar system, Olympus Mons, at a height of 17 miles, the volcano is three times higher than Earth's Mount Everest.

Planets And Solar System - 1,701 words
"A planet is a celestial body that revolves around a central star and does not shine by its own light " (Grolier, 1992). The only planetary system that is known to man is our solar system. It is made up of nine planets which range in size and make-up. The nine major planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. There are also many other minor planets which are also in our solar system, but they are unimportant compared to the nine major planets. In this paper I will discuss the planets and how they are each unique. Mercury which is the planet that is closest to the sun is the first planet I will discuss. Mercury is the smallest of th ...

The Solar System - 1,564 words
Humans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earths neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the Earths neighbours. They all have the same stars in the sky and orbit the same sun. Scientists believe the solar system began about 5 billion years ago, perhaps when a nearby star exploded and caused a large cloud of dust and gas to collapse in on itself. The hot, central part of the cloud became the sun, while some smaller pieces formed around it and became the planets. Other fragments becam ...

Analysis Of Our Solar System - 1,437 words
On a hot summer night, as you are sitting outside enjoying the evening, you tilt your head back and look into the night sky. You begin to wonder what is really out there? How far away are the stars? Are they stars or are they planets? We live in a part of the night sky called the Milky Way Galaxy. Our galaxy can be seen with the naked eye on a clear summer night. It resembles a ribbon stretched across the night sky. During the summer is when the Milky Way is at its fullest with the stars so clustered together they look like one white mass. Our galaxy is a gigantic agglomeration of stars and planets whose numbers will probably never been known. Currently we estimate this number to be about th ...

The Price Of Eating From The Tree - 1,534 words
The struggle for power is an age old one, indeed. Opposing nations vying for control of a province, officials seeking powerful positions against equally cunning rivals, and the fight for dominance in a household are all examples of this struggle. It is a mental and physical battle, fought on many different sides at once by many different means. As a species, humanity seems predisposed to seeking the upper hand, even over those they may deem allies. Advancement in science and technology gives certain nations dominance on a military and economical level. Moral issues are fought in courtrooms, in churches and on the streets. Families are torn apart as wives try to break free of the chains of op ...

Creationism Vs Evolution - 1,016 words
Evolution is not only improbable but clearly impossible. Extensive evidence against evolution is uncovered with every major scientific discovery. Every evolutionist "fact" can easily be rebuked by creationists. Twelve supposed hominoids have been discovered and presented as supporting evidence to evolution. While in all actuality nine of the twelve supposed hominids are actually extinct species of ape. While the remaining three are completely developed humans. Neanderthals were once considered pre-humans by evolutionists but recent studies have shown that the Neanderthals are completely developed humans (Homo sapiens) suffering from bone diseases caused by vitamin D deficiency. Many textbook ...

Volcanoes - 1,488 words
Which are the biggest (tallest and largest volume) and smallest volcanoes on Earth? The island of Hawaii is probably the largest volcano on earth. From its base (on the floor of the Pacific Ocean) to the summit of Mauna Kea (about 13 000ft) is some 30 000ft i.e. higher than Everest. The island comprises several coalescing volcanoes including Mauna Loa, Mauna Kea and Kilauea. Mauna Loa alone has an estimated volume of 40 000km**3. It is impossible to say which is the smallest volcano since there are thousands of small eruptions on the ocean floor and around already established volcanoes only a few yards across. Volcanoes are caused when molten rock from within the mantle breaks through the cr ...

Racism And Evolutionary Theory - 1,751 words
... osopher Herbert Spencer. A school of thought led by Spencer, an influential contemporary of Darwin's, held that some people were naturally superior to others, and that the perfection of the species required that the inferior ones bite the dust, leaving the future of humanity to their betters. This theory merged conveniently with aspects of nineteenth-century capitalism to justify economic policies sacrificing social welfare in favor of rampant capitalism and the rich getting richer. Traces of that thinking persist in one form or another to this day. To Spencer, Evolution was not only a theory of species, but also one that applied every aspect of reality. Spencer argued that everything we ...

Pink Palace Museum - 585 words
When I first moved to Memphis, I decided that I wanted to learn more about my new hometown. I thought that the museums would be the perfect place to help me learn more about Memphis. There is one museum in particular that I will never forget. It is called The Pink Palace Museum. The Pink Palace Museum is a pink grand palace made of pink bricks and pink Georgian marble. Before the palace was transformed into a museum, it was intended to be the home Charles Saunders, founder of the Piggly Wiggly grocery store. Allegedly, Saunders had paid to have his dream home built. Unfortunately, his dream was destroyed when he had to file a Chapter Eleven because of his outstanding debt. The city of Memphi ...

Asteriods - 332 words
Asteroids are some of the many small or minor planets in the solar system that move in oval shaped orbits mostly between Mars and Jupiter. The largest of all asteroids is Ceres, with a diameter of 1030 km. Pallas and Vesta are next with diameters of 550 km each. In all, there are about 200 asteroids with diameters of more than 97 km with thousands of other smaller ones. Though plentiful, the Moon's mass still belittles the total mass of all asteroids in the solar system. The larger bodies tend to have a spherical shape while those with diameters less than 160 km can be elongated and irregular. Regardless of the size of the asteroids, most rotate on their axis every 5-20 hours. Some asteroids ...

Nemesis - 2,050 words
The "Nemesis Theory" was an outgrowth of the discovery of Alvarez et al., that the impact of a large (10 km diameter) comet or asteroid was responsible for the great mass extinction that took place 65 million years ago. Studies of the fossil record by Dave Raup and Jack Sepkoski shows that this was not an isolated event, but one of several mass extinctions that appear to occur on a regular 26 million year cycle. Their original paper analyzed marine fossil families, and was published in the Proceedings of the National Academy of Science USA, vol 81, pages 801-805 (1984). The original extinction data of Raup and Sepkoski are replotted in the following figure. The vertical axis shows the "extin ...

... varez's case, and see if it was flawed. This job was turning out to be more fun than I had expected. On my second reading of Alvarez's letter, I found it particularly dubious that the Cretaceous and Eocene extinctions should be excluded. How do we know that asteroids do not hit the Earth periodically? I asked. Maybe our failure to arrive at a theory just meant that we hadn't been clever enough. Not finding something is not the same as proving it is not there. I decided to reserve judgment. A few minutes later Alvarez stopped by to see if I had finished, and I told him that I had found a mistake in his logic. It had been improper to exclude the Cretaceous and Eocene mass extinctions, I sa ...

Black Hole - 1,868 words
An image of the core of the Whirlpool galaxy M51 taken by the Wide Field Planetary Camera onboard the Hubble Space Telescope. It shows an immense ring of dust and gas which is thought to surround and hide a giant black hole, 1 million times the mass of the Sun, in the center of the galaxy. The ring forms an accretion disc of gas, about 100 light years across, falling toward the black hole. The two brighter areas perpendicular to the widest dark lane are two jets of particles accelerated by the black hole. Anyone who has ever watched the launch of a rocket is familiar with the concept that escape from a gravitational field requires the expenditure of energy. The stronger the gravitational fie ...

The Red Planet - 1,502 words
Named after the Roman God of war, Mars has sparked and sustained curiosity than any other planet in our solar system. Astronomers and Geologist have studied the surface of Mars dating back to 1965 when Mariner 4 swept by the planet. Photographs of the planet showed a barren surface scarred by numerous craters. It wasnt until 1976 that scientist got their first glimpse of the Martian Landscape from its surface. As we take a closer look at Mars we may find many similarities as well as differences compared to our planet earth. Mars may be considered one of the smallest terrestrial planets, but it has some of the largest volcanic and tectonic features in the solar system. The largest volcano on ...

The Telescope - 362 words
In 1609 Galileo Galilee Constructed his first telescope. Little did he know that this would be one of the greatest inventions the world would ever see. This fairly simple creation enhanced our ability to see things that are very far away and that cant be seen with the naked eye. We also learned a great many more things about earth,the rest of the solar system and the role it played in the universe. We were able to see the phases of the planets more easily and could see moons revolving around other planets. Because of this invention the Copernican theory was proven to be true in that it was proven that the Earth and all other things in our solar system revolve around the sun and not the Earth ...

Life Beyond Earth - 1,057 words
Do you think its possible to find aliens in your lifetime? The chances that an extraterrestrial civilization would actually come to the Earth are slim. However, if they did the best way to find extraterrestrial life is not by space exploration, but by electronic signals. Signals can carry words, numbers, and pictures cheaply and at the speed of light. The amount of time and energy required for the travel would be enormous. The amount of energy required to accelerate a spacecraft weighing several thousand tons to a speed even a moderate fraction of the speed of light would be billions of times more than the energy needed to send out a radio beacon (Big Ear Radio Observatory 4). Therefore, it' ...

Meteor Impacts - 579 words
Meteors are very common throughout outer space. They are being whipped around our solar system in every orbit possible. Normally they are peacefully and serenely floating through space, but one just has to look at the cratered face of our moon or Jupiters moon Callisto to see that more than a few meteors journeys through space have been interrupted. The earth has been hit before and will be hit in the future, statistics show this. We must detect the meteors a long time before they cross paths with Earth to prevent an impact. The likelihood of a significant meteor impact in the near future is extremely small, but it is still a possibility. The earth is just like every other planetary body in ...
