Hubble Space Telescope Universe Continues To Expand Energy
786 wordsThe universe begins with a cataclysm that generates space and time, as well as all the matter and energy the universe will ever hold. For an incomprehensibly small fraction of a second, the universe is an infinitely dense, hot fireball. The prevailing theory describes a peculiar form of energy that can suddenly push out the fabric of space. On a rare occasion, a runaway process called "Inflation" can cause a vast expansion of space filled with this energy. The inflationary expansion is stopped o...

Miles Per Second Speed Of Light
1,615 wordsOur universe is a vast abyss, always expanding without bound. Many objects in space are exciting and intriguing. Mysterious surround many findings and cosmologists, astrophysicists, and astronomers work to obtain a better understanding of these strange phenomena. One great mystery is that of the black hole, which since the early 1960? s has been the object of many scientists? work, but has been dated to be the topic of discussion since 1783, when a astronomer named John Michell first recorded hi...

Radio Telescopes Radio Waves
1,285 words... copes Orbiting telescopes are used to observe the ultraviolet (UV), far infrared, and X-ray portions of the electromagnetic spectrum. The Infrared Astronomical Satellite, placed in orbit in 1983, carried a 22. 5 -inch infrared telescope. Because all matter emits infrared radiation if warm, technologists had to cool the telescope to near absolute zero with liquid helium so its internal heat radiation would not mask radiation it was collecting from deep space objects. Among its many discoverie...

Food Irradiation Drug Administration
1,755 wordsAn Epic Future in Cold Pasteurization The preservation of food is essential to maintain life and growth. Its daily intakes nourish our bodies, providing enzymes, in turn giving us energy. The ability of matter exerts radiation in its domain by means of energy in selected foods. Such rationale debates whether a development of technology creates an effective way to reduce the incidence of foodborne diseases, while treating a variety of potential problems in our food supply. An effective method of ...

Carbon Dioxide Solar System
1,582 wordsHumans 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 ca...

Feet And Making Walked Up The Beach Sand
526 wordsFine white sand clung on to my damp feet as I ambled along the beach. It was a lovely afternoon and the sun was shining brightly above the horizon, with the sea soaking up some of its radiant rays, reflecting the others, and shimmering vibrantly under the sky. I could see dark outlines of birds flying way over the mountains, flapping their wings and soaring higher and further away until they were so small that they could hardly be seen. I walked towards the edge of the water and small waves coll...

Methyl Bromide Uv Radiation
627 wordsOzone is a form of oxygen that is a human-made pollutant in the troposphere but a naturally produced, essential component in the stratosphere, which encircles our planet some 6 to 28 miles above the surface. The stratosphere contains a layer of ozone that shields the surface from much of the ultraviolet radiation coming from the sun. If ozone was to disappear from the stratosphere Earth would be uninhabitable for most organisms. The primary cause for this substantial ozone loss is a group of com...

Distant Objects Whats Wrong
687 wordsThe human eye is a wonderful thing. It lets us view things. They can give us another eye color, or we could just use them to simply view things. But its not that simple you see. Some people arent that lucky, and have impaired vision. This includes near-sightedness and far-sightedness. To begin though we must understand how the eye works, and why it works that way. First is the cornea, which is a clear dome that covers the front of the eye. The cornea accomplishes the majority, which is about 70 ...

The Dangers Of Contracting Skin Cancer From Sun
903 wordsHave you ever had a sunburn that was so bad that about a week later your skin started to peel, well this happened to a woman named Sharon Lasky. In her childhood she got her share of sunburns and now is paying the price. Two years ago at the age of 40 she was diagnosed with an intermediate-stage melanoma. According to the health journal Heart and Soul, it has been proven that people who experienced blistering sunburns earlier in their life are particularly susceptible to malignant melanomas late...

Carbon Dioxide Fossil Fuels
1,092 wordsIn talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest manmade greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the ...

Carbon Dioxide Ozone Layer
1,519 wordsIn environmental science the green house effect is a common term for the role water vapor; carbon dioxide and ozone play in keeping the earths surface warmer than it would normally be. The atmosphere is primarily transparent to infrared radiation from the sun, which is mostly absorbed by the earths surface. The earth being much cooler than the sun, remits radiation most strongly at infrared wavelengths. Water vapor, carbon dioxide and ozone then absorb much of this radiation and remit a large pr...
