Sci/151 Science of Stars

Science of Stars Lyne Huffman Astronomy SCI/151 September 26, 2011 Piotr Hebda Science of Stars The following selective information explains the science of sunlight and stars. The paper includes a description of how astronomers designate reputation, temperature, speed, and rotation rate of nonadjacent objects. Additionally, an explanation of the properties of stars in the Hertzsprung-Russell diagram, located in this weeks reading, will be conducted. Finally, the acquit lifecycle of the Sun will be completed and a conclusion of where the Sun is in its lifecycle will be made. How Astronomers hold outback(a) Objects When a star is located by astronomers the news sometimes includes information concerning the composition, temperature, speed, and rotation rate of the contrary object. But how do astronomers match the information? Astronomers determine the composition, temperature, speed, and rotation rat e of distant objects with a process called spectroscopy. Spectroscopy measures light and how the light behaves. luminance is a form of cipher and the energy creates various forms of wavelengths when seen through and through different environments.

Astronomers determine the composition of distant objects due to the trend and absorption lines that all(prenominal) type of atom, ion, or molecule emits. all(prenominal) atom, ion, or molecule has a unique spectral fingermark because of the energy levels each contains. That knowledge provides astronomers with the information needed to determine the composition of distant objects. Th! e temperature of distant objects is determined due to the original fundamental fundamental interaction of atoms contained in the gas surrounding the object. Atoms, ions, and molecules collide with each other(a) causing up and down movements. The spectrum of light created by the interaction is determined by the temperature of the emitted energy; therefore, normally the color of a distant object is how astronomers determine the temperature of...If you want to get a full essay, order it on our website: BestEssayCheap.com
