Myths And Legends Oxygen Atoms
878 wordsIn certain polar regions of the earth, a rare and fascinating phenomenon occurs in the dark season of winter. This phenomenon is called the Northern Lights, or auroras. In areas where auroras can be seen, the sun shines brightly for six months and then disappears for the next six. The sun follows a straight path across the sky, rising in the north and setting in the south. This is because of the latitude of these regions. Unlike other regions of earth, the polar regions either completely face th...

Starts And Ends Brain
1,039 words... ep us in line, but we all worry if its enough. We are what we are taught, education is essential, of that there is no question, but what we are taught can some times be questionable if not downright wrong in our minds. Its all depending on the personal agenda of the teachers. Thats why there are so many religions in the world, they cant all be right, they fight terrible wars over them. Now is that not stupid? Yes we all agree, but we have our own agenda, we have everything, compared with res...

Speed Of Light Square Kilometer
1,069 wordsDo 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...

Speed Of Light Time Of Day
1,333 wordsOur view of the sky at night is possible because of the emission and reflection of light. 'Light' is the better-known term for the electromagnetic spectrum, which includes waves in the visible, ultra-violet, infra-red, microwave, radio, X-ray and gamma-ray regions. The scale of the spectrum is so large that no region is distinct, several overlap each other. Each of these regions in the electromagnetic spectrum represent transverse waves, travelling as electrical and magnetic fields which interac...

Sir Isaac Newton Laws Of Motion
1,278 wordsIsaac Newton, possibly one of the greatest scientific geniuses of all time, led a long and important life. Newton was an English scientist, astronomer, and mathematician who made significant contributions in many fields of scientific and mathematical reasoning. Newton also made important contributions to physics and astronomy. Throughout his life, Newton discovered and published many of his theories, inventions, and ideas. He devised three major laws of motion, along with the theory of gravitati...

Nuclear Fusion White Dwarf
1,160 wordsThe night sky, unimaginably deep, is a breathtaking sight. Some three thousand stars can be seen with the naked eye, twinkling points of light that have inspired the human spirit since the dawn of time. Study of the stars, based on data collected from visible-light telescopes, radio telescopes, and detectors wavelengths can now reveal extraordinary amounts of information: size, temperature, chemical composition, internal structure, distance and rotation rate, among other factors. One of the most...

Focal Length Distant Objects
1,280 wordsLight and other kinds of electromagnetic radiation coming from the universe outside the Earth must travel enormous distances through space and time to reach observers. Only the brightest and nearest stars can be seen with the unaided eye. To see farther and to clarify and measure what is seen, a telescope is needed. The word telescope is derived from the Greek words tele, "from afar, " and shops, "viewer. " Even a simple homemade telescope can clearly show Saturn's rings, Jupiter's bands and red...

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...

Radio Telescopes Radio Signals
1,153 wordsSETI, or the Search for Extra-Terrestrial Intelligence, is the scientific search for signals, primarily radio signals, from outer space. It is based on the belief that we will hear extraterrestrials before we see. The organizations work has been going on ever since the 1960 s. The main tools the scientists / searchers use are radio telescopes and listening equipment. To understand this organization, one must first look at its rocky history, and its unique discoveries. The Beginning of SETI is re...

Hubble Space Telescope Space Shuttle
585 wordsThe Hubble Space Telescope The Hubble Space Telescope is one of the worlds most powerful earth-orbiting reflecting telescopes. With its capability of producing images from any wavelength, the HST is the eyes of the universe for scientists on earth. The HST has a capability of operating at any wavelength from a near infrared level to a visible range to an ultraviolet level. Because of this capability, scientists can view toward the outmost reach of the universe. The HST has a 2. 4 meter objective...

University Of Pisa Natural Philosophy
726 wordsGalileo Galilei's father, Vincenzo Galilei (c. 1520 1591), who described himself as a nobleman of Florence, was a professional musician. He carried out experiments on strings to support his musical theories. Galileo studied medicine at the university of Pisa, but his real interests were always in mathematics and natural philosophy. He is chiefly remembered for his work on free fall, his use of the telescope and his employment of experimentation. After a spell teaching mathematics, first privatel...

538 wordsJames Clerk Maxwell Introduction James Clerk Maxwell was a British physicist. Maxwell was born in Edinburgh, Scotland on November 13, 1831. He was educated at Edinburgh Academy from 1841 to 1847. He then entered the University of Edinburgh, and went on to study at the University of Cambridge in 1850, graduating with a bachelors degree in mathematics in 1854. In 1860, he moved to London to become a professor of philosophy and astronomy at Kings College. Due to the death of his father in 1865, Max...

Then, in peacetime, [if you can call it that, but in my world it was] through the schooling years, at which I reached the pinnacle of personal achievement. The last year of my Secondary Modern School, I was top of my class. It was not that I was so smart, it was...

Radio Waves Light Waves
335 wordsRadio astronomy uses radio waves to study regions of space. Radio waves are a form of electromagnetic radiation like visible light waves only with much longer wavelengths. Visible light waves are oscillating electromagnetic signals with wavelengths of less than one millionth of a metre, whereas radio waves have wavelengths in the range of a few millimetres to several metres. Radio telescopes gather and concentrate the radio waves from an astronomical source. The signal received is then electroni...

M P H Black Hole
3,742 wordsBlack holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole. Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einsteins general theory of relativity, we have to delve into some results of this theory to understand black ...
