out in the cold unknown, there maybe an escape for when our planet dies. Somewhere out in space there is a medal telescope just floating around pionted at a habital zone for planets. this is NASA's creation called Kepler." Kepler is a specially designed 0.95-meter diameter telescope called photometer or lightmeter. It has a very large veiw, about 105 square degrees" (Hunter).
This is also commonly referred to as a shooting star and sometimes mistaken as a comet. When any of these threats enters the Earth’s atmosphere and impacts the Earth, they are called meteorites and are often referred to as meteors. For the purpose of this paper we refer to all the above as “meteors”. Meteors exist in space and range in size and composition. The origin of meteorites has been linked to the moon, and Mars, while the rest of the “meteors” are believed to be fragments originating from asteroids, comets, and other planetary debris.
Dark Matter”). While observing the Milky Way, astronomers Vera Rubin and W. Kent Ford confirmed the existence of dark matter during the 1970s when they discovered stars on the galaxy’s outer rim orbiting at the same speed as those near the center (Reis, “Dark Matter). Under the existing laws of gravity, stars at the outer rim would have to orbit at a slower rate than those near the center in order to stay in the galaxy’s rotation (Reiss, “Dark Matter”). This indicated the existence of an unseen force that was creating a gravitational pull. During the past 20 years, X-ray telescopes have also identified the existence of unseen matter in the form of hot gas within clusters of galaxies (Reiss, “Dark Matter”).
Life Cycle of a Star Pamela Hughes May 17, 2011 SCI/151 Norman Stradleigh Life Cycle of a Star On a clear dark night, one can see thousands of stars. We can see many stars but could never dream of being able to count them all. Even though each individual star is unique, all stars share much in common. The Sun, which is the source of virtually all light, heat, and energy reaching the Earth, is the nearest star. Today, we know that stars are born from interstellar gas clouds, shine by nuclear fusion and then die, sometimes in dramatic ways.
Meteorites are naturally occurring objects that originate in space and survive a fall to the ground through Earth’s atmosphere. (What are meteorites?) Most are remnants of asteroids or possibly comets. However, a few have been shown to be pieces of Moon or Mars that were launched into space by an impact event. While moving through space these objects are known as meteoroids.
Astronomers detected the alien world as it passed in front of its sun, a red dwarf star 40 light years away in a constellation called Ophiuchus, after the Greek for "snake holder". The discovery, made with a network of amateur telescopes, is being hailed as a major step forward in the search for planets beyond our solar system that are hospitable to life as we know it. Measurements suggest the planet is shrouded in a thick atmosphere of hydrogen and helium that blocks visible light from its sun, plunging the watery surface into permanent darkness. The weight of the atmosphere keeps the water liquid despite it being a searing 120C to 282C. Writing in the journal Nature, David Charbonneau at the Harvard-Smithsonian Centre for Astrophysics describes how his team used a suite of eight amateur-sized telescopes to spot the planet as it moved across the face of its star, which is less than 0.5% as bright as our own sun.
Planetesimals collided and became bigger thus creating planets. Planets that were close to the sun, the inner planets, were so hot and dense that they formed small and rocky while the outer planets were farther away from the sun consequently become cooler in order for some comets to be formed. Evidence that of the big bang is very great. The great American astronomer
The Geology of the Moon Approximately 4.5 billion years ago a large asteroid struck Earth and thus resulted in the Moon. This impact theory suggests that the collision ejected raw materials which in time became the Moon. With the Moon having no significant atmosphere, it can reserve a good record of the impact history. This information can provide geologists with clues to the history of the Earth. The crust of the Moon is composed of a variation of primary elements, including uranium, oxygen, thorium, potassium, silicon, magnesium, iron, titanium, calcium, aluminum and hydrogen.
Saturns Moons The planet of Saturn is an amazing planet as far as moons go. This planet is currently known to have fifty-two moons. Some of these moons are spherical in shape much like Earths moon and some look to be no more than a meteor that was captured by the huge planet. Now Im not going to be able to discuss every moon that belongs to Saturn but I will talk about the six biggest which are: Titan, Rhea, Iapetus, Dione, Tethys, and Enceladus. All of Saturns moons were named after Greek Mythological figures.
