Clouds are usually the last things astronomers want to see in the sky, but for those who observe in the southern hemisphere there is a notable exception to that celestial rule.
The Large and Small Magellanic Clouds are among the highlights of the southern night sky. Only within the last century were astronomers able to verify their true nature. Although they seem to be two foggy patches possibly torn from the Milky Way, astronomers believe these are actually small galaxies gravitationally bound to the Milky Way like moons around a giant planet. The two Clouds of Magellan are like binary stars that gravity draws together to form a satellite galaxy.
Of all the galaxies in the entire Universe these are the closest to our galactic system. About 170,000 light-years away from the Milky Way galaxy lie the Large Magellanic Cloud. With only 15 billion young bright stars, it is just one-quarter the size of our own galaxy. During the winter of 1987, a Canadian astronomer, Ian Shelton, spotted the first naked eye supernova since 1604, the result of a massive explosion. No more exciting and scientifically significant event has occurred over the last decade in science than Supernova 1987A, as it is known. Photographs taken on the night of February 23, 1987, of the Large Magellanic Cloud, a companion galaxy to our own Galaxy, at Canada's southern hemisphere observatory at La Silla, Chile, and at the Siding Springs Observatory in Australia, revealed a 6th-magnitude object where only 12th-magnitude blue supergiant stars had been observed before. Scientists believe that the progenitor of Supernova 1987A is a typical blue supergiant of spectral type B3. Spectra taken in 1977 do not suggest anything unusual happening in the outer layers of the star prior to undergoing the supernova outburst. This is not surprising since the real changes were occurring deep inside in a relatively tiny portion of the star's radius. The Large Cloud is quite important because it is the location of this Supernova 1987A, the exploded star that for a time shone brightly but that is now dim and dead.
Farther away than the Large Cloud, the Small Magellanic Cloud is approximatly 200,000 light-years distant. It is roughly a third the size of the Large Cloud, consisting of only 5 billion older stars.
The nebulas were named after Portuguese explorer Ferdinan Magellan, the first person to sail around the world.

Messier 8, nicknamed the Lagoon Nebula is an interstellar cloud located in Sagittarius, discovered by John Flamsteed in 1680. It is one of the few nebulae that can be seen by the naked eye. It was given its nickname by Agnes
Distances so vast that the light from those areas in space is billion years old. Illingworth was able to see these ancient giants with the Hubble Space Telescope. A telescope that is high above the atmosphere, because it can distort the image. 100 sextillion miles or 17,010,779,502.32 light years is the most distant galaxy Illingworth
Chipotle has grown to become a leader in the fast food arena. According to Our Company,
Chipotle’s provides a simplified and delicious menu to its customers. Burrito bowls, quesadillas, flour tortillas and corn tortilla tacos, salads, soft and alcoholic beverages. The price of each item varies depending on what type of protein is chosen. Choices of grilled chicken, steak, carnitas, barbacoa, steak, or vegetarian. They also have a variety of fresh salsas, such as, sour cream, cheese, or lettuce and guacamole. Each restaurant has a unique style inspired by the Mayans. The furniture and arts are made from pressed, recycled paper which is more durable and sustainable.

For example, the Cumulo de Pegaso is located off the tip of Pegasus’s nose and is known for its intensely bright center (Pommier, Rod). Cumulo de Pegaso was discovered by Jean-Dominique Maraldi in 1764 (“Pegasus Constellation”). Unlike Cumulo de Pegaso which can be seen with a small-telescope, Stephan’s Quintet requires a large telescope (Bakich, Michael E). Stephan’s Quintet is the first compact group of five galaxies. Edouard Jean-Marie Stephan discovered Stephan’s Quintet in 1877 (Berman, Bob.). In 1784, William Herschel discovered the Propeller Galaxy. The Propeller Galaxy is undergoing star forming activity, resulting in the S-shape it was named after “Pegasus Constellation”). Also in 1784, William Herschel discovered the spiral galaxy of NGC 7331. NGC 7331 resembles the Milky Way in size and structure (“Pegasus Constellation”). Lastly, Einstein’s Cross includes four quasars that show the phenomenon of gravitational lensing. Einstein predicted gravitational lensing in his general theory of relativity, claiming that gravity would be able to bend light. This prediction led to Einstein’s Cross’s name (“Pegasus
Similar to a fast food restaurant, but more upscale with a better dining experience. Ells idea of keeping the menu simple with limited items to prepare delicious food efficiently helped to create a kitchen different from other fast food chains. Food preparation areas in Chipotle’s kitchens are similar to those of fine dining restaurants. Menu items are prepared from scratch and with fresh ingredients. Even the meats are prepped with marinades. Creating such recipes is very labor intensive, but having limited items to prepare assists in keeping the cost down. The focus on menu integrity is one of Chipotle’s advantages and is a key element to their marketing strategy. One way Chipotle is able to control their ingredients and maintain menu integrity is by controlling their suppliers. After working with certain suppliers, they created a list of approved vendors for the individual restaurants to purchase from. One reason was to try and help control costs. Healthier food items cost more and Chipotle wanted to keep the cost of their meals low for their customers, so they built relationships with certain suppliers. Eventually, they began to use distribution centers across the country that only purchased ingredients from their approved suppliers (Gamble, Peteraf, & Thompson, Jr., 2015). This approach separates Chipotle from competitors like Taco Bell. Serving high quality food at a competitive price point against other fast food

In class I was looking forward learning about the Milky Way, it was something I have been interested in for some time. So in this paper I am going to expand on what we learned in class and talk a little bit more about our Milky Way. So The Milky Way is one of the cosmic galaxies that are made up of billions of stars. The solar system, which is part of Earth, is located in the galaxy. There are many legends about the name of this galaxy. The people our earth can see this galaxy and its stars on clear nights. Its stars look close despite the distance, giving a calm white color that looks like Milky way. In ancient Greek mythology said that “Heraclius wanted to suckle from Hera, but he could not.” He felt very disappointed and the
The Andromeda Galaxy being 220,000 light years across is the biggest of its local galaxy group which includes the Milky Way Galaxy, Triangulum Galaxy, and about 44 smaller galaxies. The Andromeda Galaxy contains about (1 trillion*10to the 12th power) stars, which is more then double the estimated 200- 400 billion stars located in our own Milky Way Galaxy. Along with this the Andromeda Galaxy has a brightness magnitude of 3.4 making it one of the brightest of all the Messier Object group.
There is a long history of astronomy in science fiction. Some of the earliest can be seen with the Greeks, with their tales of gods representing the parts of the universe they could see. Other cultures began writings of men going beyond the limits of the atmosphere as early a...
The theory of Maslow’s hierarchy was created in order to understand what is the motivation for others, and was defined by Abrahm Maslow as stated from the “Understanding Canadian Business” textbook (327). However, motivation is created because of needs, as people become motivated to accomplish their needs as stated from the “Understanding Canadian Business” textbook (327). Although needs, as defined in the “Understanding Canadian Business” textbook, is separated into five different categories; physiological, safety, social, esteem and self-actualization (327). Furthermore, physiological are needs which allow a person to survive, like having water; safety needs is where workers need to feel secure at their workplace and at their home; social
The first need theory is Maslow’s Hierarchy of Needs Theory. Grensing-Pophal (2002) stated that Maslow developed five levels that describe the needs of a person. The first level is physiological comforts. These are the basic survival needs of a person, such as food, water and shelter. The second level is safety needs. Ramlall (2004) further described these safety needs in three areas: economic (such as wages and benefits), psychological (such as work stability), and physical (such as physical work environment and breaks). The third level is social fulfillment needs (Grensing-Pophal 2002). These needs deal with friendship and interacting with other people. The fourth level is satisfaction of the ego. These needs focus on being respected, self-esteem, and recognition. The final le...
