Five-pointed star

100 billion stars in our galaxy alone. Space is never ending filled with countless amounts of galaxies that we cannot even begin to understand. There are so many stars and so many lives. They have different sizes and shapes and they can turn into different things after they die based on their size and shape. The exact definition of a star is a fixed luminous point in the night sky that is a large, remote incandescent body like the sun, however, stars are much more than that. Stars are related…

group of stars movement that orbits an area in a space. In other words, when gas enters stellar black hole from a companion star, the gas twists inwards, heating at a very high temperature and producing huge amounts of radiation that can be noticed from earthbound and earth-orbiting telescopes. Locations that black holes can easily be found have been identified. One likely area is at the middle of galaxies. At this region the concentration of stars increases the possibility of larger stars to…

solar system. Without it, life wouldn’t be able to survive on earth. It has lived for billions of years, providing energy and light. Nothing can live without it. The Sun, which is also called Sol, is estimated to be 4.6 billion years old with up to five billion years left in its life. It is currently in its yellow dwarf phase of life. It is located in the Milky Way galaxy in a spiral arm known as the Orion Arm. The Sun orbits the center of the galaxy at a speed of 720,000 kilometers per hour,…

occur in the universe, there are not many that equal the power or beauty of a supernova. Supernovas occur at the end of the star’s life cycle as the star depletes its fuel. According to NASA, as the star runs out of fuel, a portion of the stars mass flows towards the core. This causes the core to grow and eventually due to the gravitational forces of the star, collapses the core causing a spectacular explosion. While it is theorized that a supernova occurs once every second in the universe, few…

constellation that has three stars with no known planets. The major stars in the Camelopardalis constellation are, Beta Camelopardalis, which is the brightest star and is binary with a yellow G-type supergiant. CS Camelopardalis, the second brightest and is also binary with a blue-white B-type supergiant. Sigma 1694 Camelopardalis, also binary with a white A-type subgiant. Lastly, VZ Camelopardalis, an M-type red giant. Because it was so faint, the Greeks did not see any stars in the…

myth/legend is very interesting and it is a very unique creature to me. The Pegasus lies in the Northern Hemisphere and it is the seventh largest constellation in the sky, occupying an area of 1121 square degrees. This constellation is made up with 9 stars--Scheat, Matar, Salm, Algenib and Markab. The brightest is Markab. This constellation's name came from Pegasus, a white winged horse. The most famous/well-known Greek myth involving Pegasus is the one of Bellerophon, the hero who was sent by…

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…
