energy from a nearby star. Moreover, when Hubble in 1922 found a relation between the magnitude of the central star and the size of the PN, he proposed that the emission spectrum of PN is the result of the absorption of the continuous spectrum of its central star’s radiation (Kwok).…

Fundamentals of Orbital Mechanics This chapter applies the principles of physics for describing motion of artificial satellites and planets which are moving under the influence of gravitation force. It also presents an accurate gravity model for flight dynamic applications (for use in subsequent chapters). 2.1 Kepler’s Laws of Planetary Motion In 1609 Kepler has presented his three laws for describing motion of planets around the Sun. These laws are empirical because Kepler has found them…

Abstract— The Hotel industry is a typical service focus business. It has been driven by tourism in Singapore for the past few decades. Facing intensive competition, hotels not only offer just a place to live away from home but a kind of customer satisfaction through expected services. Shangri-La Hotels and Resorts belong to the luxury hotel sector and a leader in the upscale hotel industry; it continues to face competitions from its rivalries. This paper discusses the Shangri-La Hotel and…

using two different methods: by studying the oldest objects within the universe and measuring how fast it is expanding. Experts agree that the universe cannot be younger than the objects contained inside of it. By determining the ages of the oldest stars, scientists are able to put a age limit on the universe which is 13.7 billion years old. A forever expanding universe? The expansion of the universe depends on how much matter the universe contains. Scientists predict that if there is enough…

NGC 582; (left) and the 15.2 magnitude PGC 1028168. (Right). While NGC 582 was an easy object in the 18 inch, the PGC galaxy was not seen with certainty. A galaxy is, by definition, any large collection of stars that can be recognized as a distinct physical entity. In terms of the number of stars, a small 'dwarf irregular'…

Diagram Lab-Plotting the Stars Part I: Introduction 1) One method scientists use to measure the distance of the star is called parallax. Parallax shift is when closer stars shift positions against the farthest stars. In order for astronomers to measure that distance, they measure the distance of the shift, also considering the diameter of the Erath’s orbit. Then the angle of the parallax is measured. The smaller the angle of the parallax shift is, the farther away the star is from the earth…

resolve individual stars, along with open star clusters, globular star clusters, and even glowing regions of fluorescent gas. The spiral arms, which wind all the way down into the nucleus, are made up of young, bluish, hot stars formed in the past few million years. They also host a population of stars formed in an episode of star formation that started about 600 million years ago. The greenish regions are dense areas of bright star formation. The ultraviolet light from hot young stars are…

Messier added this galaxy to his catalog of nebulas objects, known as the messier catalog. Later on June 6, 2006 the Galaxy Evaluation Explorer, from NASA, found that there were a large number of new stars on the outer rim of the galaxy, which was believed to be lacking in the material needed to make a star. The Galaxy Evaluation Explorer also found…

tilt of 23.5 degrees relative to the “ecliptic plane” the imaginary surface formed by its almost circular path around the sun the tilt towards the sun is maximised during northern hemisphere summer in late June the summer solstice. There are so much stars in the galaxy that some of them we can not discover in the universe.At night you can see some of the milky way. The sun is actually closest to the Northern hemisphere in winter not summer and the sun is always closest to the Northern…

Female pop stars have been a force to reckon with within the modern music industry and have dominated music charts around the globe. Each female pop star creates her own unique sounds, lyrics and catchy music to entice a fan base to follow them. However, are female pop stars really that different? Jennifer Lena argues in "Chapter 2: Three Musics, Four Genres: Rap, Bluegrass and Bebop Jazz" that "music histories are full of hints that there is a pattern to the evolution of communities of sound"…
