Life cycle of a star Stars are born in nebulae. Huge clouds of dust and gas collapse under gravitational forces‚ forming protostars. These young stars undergo further collapse‚ forming main sequence stars. Stars expand as they grow old. As the core runs out of hydrogen and then helium‚ the core contacts and the outer layers expand‚ cool‚ and become less bright. This is a red giant or a red super giant (depending on the initial mass of the star). It will eventually collapse and explode. Its fate

Democritus was an Ancient Greek pre-Socratic philosopher of Ancient Greece. He along with Leucippus were atomic theorists who proposed during the fifth century B.C that 1. Matter is composed of atoms separated by empty space by which atoms move. 2.Atoms are solid‚ homogeneous‚ indivisible‚ and unchanging. Democritus knew that if he took a rock and chisel it in half‚ that both halves would characteristically have the same properties as the whole. He rationalized that if he was to continue to cut the

The Orion Nebula contains one of the brightest star clusters in the night sky. With a magnitude of 4‚ this nebula is easily visible from the Northern Hemisphere during the winter months. It is surprising‚ therefore‚ that this region was not documented until 1610 by a French lawyer named Nicholas-Claude Fabri de Peiresc. On March 4‚ 1769‚ Charles Messier inducted the Orion Nebula‚ M42‚ into his list of stellar objects. Then‚ in 1771‚ Messier released his list of objects for its first publication

This spectacle is happening . as it begins to glow‚ we all become witnesses to this divine beauty personified- million of stars is born and we call them the freshmen. It is truly a mystery how such formless gas and dust ignite the crystal of dreams and unlock the mystery of star formation

Abstract The needs for an instrument that would take images of the universe from the space were inevitable since there were so many challenges studying space and the universe from earth. The Hubble telescope‚ named after the great scientist who confirmed the big bang theory‚ was the solution to this and it has been in space for the more than 20 years it was supposed to live. Over the time‚ the telescope has sent home so much information that mankind has realized how little they knew about the universe

It would be nearly impossible to document every occurrence from ~13.7 billion years ago (the proposed beginning of the universe) to the present; however‚ comedic author Bill Bryson manages to provide great intellectual insight into many complex topics while still making entertaining remarks. Although he may be no expert in the arcane fields of quantum physics or mathematics‚ Bryson relied on a wide variety of sources (e.g. scientific research papers‚ interviews with experts) to compile this readily

Summarize the concepts that you used in the lab (1-2 paragraphs). For lab 11‚ I used the concept – Stellar Evolution. It is the process of 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
