Kleene star

The Sun is a massive, white ball of gas that fuels the 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…

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…

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…
