Modern technology‚ however‚ has pieced together a clearer image‚ “a bubble-shaped shroud of gas and dust‚ 14 light-years wide and expanding at 6 million kilometers per hour (4 million mph)” (Hill). But what‚ exactly‚ makes a supernova? What is a supernova? The word itself is easy enough to understand with a basic knowledge of the words that make it up‚ a combination of understood “super”‚ (very large or powerful)‚ and “nova”‚ (a star that suddenly increases its

so far away‚ we cannot visit them and find out what they are made of‚ what temperature they are and so on. The way that scientists decide what a distant star is made of‚ how hot it is and other things is to study the light that the star gives off. The study of light is called spectrography. By making careful observations of the light that a star gives off‚ or the light that is reflected from a planet‚ scientists can find out a lot of information about

Astronomer Essay 4/12/2011 JMJ Dr. Debra Fischer – Astronomer An astronomer is an astrophysicist who studies stars‚ planets and galaxies. Astronomers use the laws of physics to investigate the matter and energy of celestial bodies. They then apply the research findings to solve space navigation and communication problems and even discover new planets and stars. In 1512‚ Copernicus theorized that the planets orbit the sun and the race to uncover new planets began. Historically‚ most

Astronomers have been studying the stars since the first person laid eyes upon the night sky. Thousands of years of observations and recording all of the events have all contributed to the vast knowledge we enjoy today. The purpose of this paper is to describe the creation of stars‚ destruction/ life cycle of stars and our star the sun. Within this last century‚ we have been fortunate to have the great minds of Einstein and Hubble who made valuable contributions to our current understanding. Also

showing a star changes over the course of the time. Also‚ it relates to the mass‚ ages‚ sizes of the stars. Also‚ I used the Hertzsprung-Russell (H-R) diagram concept to classify the stars and find the Main Sequence. When the stars are hotter and more luminous‚ they main sequence tends to follow a band going from the bottom right to the top left at the diagram. This concept can help to classify the stars‚ such as main sequence stars‚ red giant‚ blue giant‚ supergiant stars‚ virtually dead stars‚ and binary
