Space: The Final Frontier
Astronomy is a word derived from Greek; it comes from the merging of two words, the first being ‘star’ and the second being ‘law.’ Like the name suggests, astronomy is the study of stars, in addition to countless other aspects of space and the universe in general. Being such a broad subject, there are of course many different branches of astronomy. These include general astrophysics, theoretical astrophysics, astrobiology, physical cosmology, galactic astronomy… you get the idea. (wiki) There are a lot. But the overarching theme of them all is space, especially the physics of space. And wherever there is physics, there is math.
Like math, astronomy incorporates a healthy (or-not-so-healthy, depending on your perspective) usage of symbols. These symbols are often times greek letters, like in many other forms of equations. These symbols are commonly used in formulas. There is practically an astrological formula for everything; formulas to calculate brightness, distance, luminosity, and a myriad of others.

The formula in fig. 1 is used to calculate kinetic energy (The energy an object has due to its motion) of an object. This is formula is applicable in many ways. For example, it can be altered to find the energy of unbelievably small units, such as molecules and atoms. This altered formula can be seen in fig. 2. Every object moving in space has kinetic energy (http://m.teachastronomy.com/astropedia/article/Potential-and-Kinetic-Energy). Kinetic energy is all around us, for example if you’re driving on the street and pass two cars of the same make and model, the car going faster will have more kinetic energy than the slower. Kinetic energy is seen al...

...based on their mass and size. They are listed as Supermassive, Stellar, and Miniature. Supermassive—the type of star that lies in the center of a galaxy—are the largest black holes among these. Astronomers believe supermassive black holes grow when object pass the event horizon (an imaginary sphere around the black hole where the escape velocity is greater than the speed of light). Stellar black holes are remnants of large stars, as was explained earlier. These are the most commonly formed type of black hole. Finally, there are Miniature black holes, like the one mentioned in the oreo analogy. One possible origin of these Miniatures would be in the dawn of our universe, during the Big Bang. Matter would have been compressed into a single point and then then expanded rapidly. Some parts may have expanded more rapidly than others, thus creating a Miniature black hole.
The Bible was one of the most important pieces of text during Galileo’s lifetime. If you went against what the Bible stated then you were considered to be a heretic. The Bible indicated that the earth was in the center of the universe and the sun and the other planets revolve around it. a theory known as the geocentric model. Many scientists argued against this theory by stating that actually the sun was in the center of the universe and the earth and the other planets revolved around the sun, this theory was known as the heliocentric model. Nicolas Copernicus was one of the first out of many scientists who publically shared this theory. Later Giordano Bruno also supported this theory and because of this the Church ordered him to be burned
It is believed that super massive black holes exist in the cores of many large galaxies, including the Milky Way galaxy, which is our galaxy. (Swinburne University 2014). It is believed that a normal black holes were formed because of a supernova explosion of a gigantic star, meaning when huge stars collapse, so the larger the star, the larger the black hole. ( Millis 2014) . So therefore a simple idea of how a super massive black hole might have been formed would be because of a collision of super enormous star or a collision of star clusters (star clouds). (Super massive black holes 2014)
In the novel, October Sky, it is a story about a boy who has a dream to make rockets and not just be a coal miner. After graduating high school, the boys of Coalwood would normally go into the career of coal mining or be lucky enough to get a football scholarship. Sonny had no interest in coal mining and was not athletic; both of those choices were out of the picture for him. He is the son of Homer, a coal miner, and Elsie Hickam. He also has an older brother named Jim who was an amazing football player. Sonny and his five friends wanted to be something other than coal miners. They formed a group called the Big Creek Missile Agency aka the BCMA. The six of them worked very hard to learn calculus, test different types of fuels, and get a textbook about rockets for the school, to make the best rocket. Sonny was a product of the setting he made, he broke free from the Coalwood setting, and he was successful doing it.
Kinetic Energy = the energy an object has because of its movement. An object has more kinetic energy the greater its mass and speed. Prediction = ==
A black hole is created from a sun going into a supernova. It starts in the middle of the sun. Its mass collapses on itself to create a super nova. Once the supernova happens ...
Astronomy is a very important field in science. Ancient Greece, China, and India all contributed to our everyday ideas and uses of astronomy. Ancient Greece was the most influential because the Indian’s based most of their astronomy off of Greece. The Greeks created calendars that were based off of the eclipse cycle, which they called by two different names, Hellenic Calendars and Lunisolar Calendars. Because of Ancient Greece, we now have calendars to keep us on track every day. The Greeks observed a celestial object passing through the eastern and western morning sky. After a long time of observations, they came to a realization that it was a planet and now that is the planet is well known as Venus. (Sarton, 75) Plato and Aristotle’s theories were incredible contributions on us today. Both of their theories were all about the behavior and life of the planets, such as their theory that the earth is spherical. (Sarton, 421). Ancient Greece als...
In four years from now, space tourists are going to have a new destination in the orbit. The startup which is known as Orion span, is aiming to loft it's 'Aurora Station' in late 2021 and by 2022 it should be set to accomodate guests. Frank Bunger, the orion span CEO and founder said 'We are launching the first ever affordable luxury space hotel' He unvieled this Aurora idea on the 5th of April at the Space 2.0 summit in San Jose, California.
Cyber Attack on Island of Telescopes Not only is Hawaii a sort of paradise, it’s also what seems to be a native and comfortable habitat for larger telescopes. Since Hawaii is much further away from any light and has minimal air pollution, it’s a perfect spot to look up at the night sky. Right on the island of Mauna Kea lives thirteen different telescopes, including the coming TMT or Thirty Meter Telescope. It will become an island of telescopes if it hasn’t already.
In 1910, Arthur Eddington, a British Astrophysicist, discovered solar winds. Solar winds are basically a continuous flow (they are never ending basically) of particles from the sun. They are also known as stellar winds. Their usual way out of the sun is the coronal holes. Their main cause is an expansion of gases in the corona, which is the outer layer of the sun. The idea that the corona is plasma was thought of by Richard C. Carrington. The temperature of the corona is 2,200,000 degrees Celsius. It is so hot that not even the sun’s gravity can contain it. It heats gases and makes them expand. The gas items run into each other as they are heated. As a result, they lose their electrons. Then, the atoms become ions with a positive charge, the electrons and ions (which are mostly Hydrogen ions) make up the solar wind. The velocity of solar winds goes from 250 to 1000 kilometers every second. It has a density of 82 ions for every cubic inch, or 5 ions per cubic centimeter. Solar winds are the cause of many occurrences in the solar system like Mercury having no atmosphere, and Venus’ acidic, radiation filled clouds. They are also known as electrically charged hurricanes.
In the novel, Stardust, written by Neil Gorman, there are many important quotes that pertain to the overall plot. Stardust, is a non-fiction novel that included elements of suspense, thrill, and romance. The overall theme of the novel is romance from a different element, a star. Tristran Thorn, had his heart set on his dream girl, Victoria Forester, however she had heart taken by someone else. A shooting star fell one day in the city of Babylon. Thristran made Victoria a promise that if he captured the star and bring it back to her she will marry him. Tristran set apart one day to go find the fallen star. Tristran ended up finding the star, however, instead of ending up with his sweetheart Victoria, he ended up with his
According to ushistory.org, governments are formed to protect people from conflicts and to provide law and order. Although an asteroid wiping out the entire earth is not technically a conflict, it would probably be difficult to do those things if the earth was uninhabitable and everyone was dead. So, of course the government has an obligation to search for and protect people from killer asteroids. At the moment, NASA has the Planetary Defense Coordination Office as part of its planetary science division. PDCO is responsible for all NASA-funded projects that search for and catalog asteroids and comets that pass near the earth.
...either sp3 hybridization or an alkyl group. By looking at the chemical structure, we can see that two methyl groups are present, and this peak confirms this.
There are eight planets in our solar system. The first planet closest to the sun is Mercury. Therefore, Mercury is the hottest planet. Mercury’s surface is cold. However, in the daytime Mercury can get as hot as 840 degrees fahrenheit, which is 450 degrees celsius. During night time the temperature can decrease to 275 degrees fahrenheit, or -170 degrees celsius. Mercury is the smallest planet. Mercury is the quickest planet to move around the sun. Its speed is approximately 112,000 mph along its elliptical orbit. Mercury can move around the sun in 88 days. There are craters in mercury, and scientist believe ice is in the craters.
...roups that have been important to astronomy are the Akkadians, Egyptians, Chinese, Polynesians, and the Greeks. They used astronomy for navigation at sea, creating accurate calendars, making new inventions, and many more things! Some modern jobs in astronomy include Educational, Private industries, National Observatories and Laboratories. Also, some technical advances because of astronomy include many telescopes, tracking programs used by FedEx, and IRAF which is used to analyze computer systems. Even though astronomy is an incredibly interesting field, there are minimum job opportunities. Some of the jobs are included in the following fields: education, national observatories and laboratories, or in private industries. Astronomy has been the key to unlocking many new inventions and by connecting things from the past, to the present, and going into the future.
