Reading This Article Neutron Stars
569 wordsIn November of 1999 an article about cosmic cataclysms appeared in Time magazine. A cosmic cataclysm is also known as a gamma-ray burst. These gamma bursts cant be seen with the naked eye and they release more energy than our sun releases in its whole lifetime. As of now, no one is really sure whats causing these large blasts. Hopefully this will change as astrophysicists meet to discuss the blasts and as satellites are launched into space to capture the phenomenon. Even though no one is positiv...

Billion Years Ago Carbon Dioxide
1,230 wordsOur 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 scienti...

Planet From The Sun Solar System

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 ...

What Would Happen If The Moon Were Destroyed
1,095 wordsWhat would happen if the moon was destroyed? I have often wondered what would happen if the moon were destroyed and how it would be destroyed. Would a crazy scientist nuke it? Maybe an asteroid would hit it. Astronomers have catalogued all large objects in space that are larger than 500 kilometers in diameter and non-of them seem to be headed towards our moon. Based on this information, the only conclusion that I can come up with, was if the moon was to be blown up by some crazy scientist. Many ...

Galaxy Its Spiral Shape Galaxy Its Spiral Galaxies
1,100 wordsWhen you look at a distant galaxy, you are not only seeing into space, but far into the past as well. The light from one of the galaxies we see today actually started its journey toward Earth more than two million years ago. The discovery of galaxies [ 1 ] began in the early 1400 s by Polish astronomers and continues to be studied today. Knowing as we do today that the universe is amenable to investigation, and that telescopes can examine millions of galaxies at distances of millions of light ye...

Thirty Years War Tycho Brahe
979 wordsJohannes Kepler was born at 2: 30 PM on December 27, 1571, in Weil der Stadt, Wrttemburg, in the Holy Roman Empire. His family was Lutheran and he adhered to the Augsburg Confession. This adherence later caused him hardships. He was a sickly child and his parents were poor. But his evident intelligence earned him a scholarship to the University of Tbingen. There he was introduced to and delighted in the ideas of Copernicus. In 1596, while a mathematics teacher in Graz, he wrote the first outspok...

Many other western countries had encouraged America to take leadership in the west because of its stability and ability to ensure protection to the other smaller, less powerful countries.

Gas And Dust Carbon Dioxide
1,584 wordsAsteroids sling through space, celestial debris of diverse origins, leftovers from the formation of the solar system, broken offshoots of parental asteroids or comets that have lost their glow. But if an asteroid were to smash into Earth, the result would mean a global catastrophe and life on our Planet could come to an end. The explosion would approach that of a million megatons of TNT- sixteen hundred times greater than the most powerful nuclear weapon ever tested (Barnes-Svarney 234). Asteroi...

Big Bang Theory Force Of Gravity
1,630 wordsNot so much a theory of the universe as a simple picture of the planet we call home, the flat-earth model proposed that Earth? s surface was level. Although everyday experience makes this seem a reasonable assumption, direct observation of nature shows the real world isn? t that simple. For instance, when a sailing ship heads into port, the first part that becomes visible is the crow? s-nest, followed by the sails, and then the bow of the ship. If the Earth were flat, the entire ship would come ...

Back And Forth Stimulated Emission
1,080 wordsThe light from lasers differs from ordinary light in several important aspects. Ordinary light from a light bulb travels randomly in all directions (unless the bulb is equipped with an integral reflector that directs the light). The light is thus incoherent. Even when incoherent light is directed with a reflector, it still spreads rapidly. The light from a laser is temporary and spatially coherent. This means that all of the wave-fronts of light are lined up in time and space (see Diagrams). The...
