The Origin of the Universe As Told by the 20th Century Peoples of North America and other industrialized lands INTRODUCTIon The evolution of theories about the origin of the universe has surely proceeded at a rapid pace upon entering the 20th Century. New telescopic devices permitting people to see parts of the universe never before imagined‚ in new ways never before conceived‚ have advanced man’s theoretical capabilites on explaining the origin of the universe‚ a task that has been

Comets Belinda Scott Introduction to Physical Science – SCI 110 Dr. Paul A. Belony‚ Jr. | | A comet is a small body‚ roughly the size of a small town‚ in the Solar System. It is made up of ice‚ rock‚ dust‚ carbon dioxide‚ ammonia‚ methane and more. Some researchers think comets might have originally brought some of the water and organic molecules to Earth that now make up life here. Comets become visible as they near the Sun. The tail of a comet is its most

1. Describe the nuclear fusion reaction that occurs in stars. Page 294 Stars are made primarily of the almond hydrogen the most common material universe. As a star forms‚ gravity pulls the hydrogen into a dense ball that heats up. Electrons are torn from the hydrogen and other atoms‚ creating a plasma made up primarily of protons (the nucleus of the hydrogen atom) and electrons. Normally‚ protons would repel each other. As matter accumulates ending the new star however‚ the protons move

In a few sentences‚ describe Hubble’s two major findings about nebulae and explain how they led to the development of the Big Bang theory. Hubble started working at a California observatory in 1919. Back then the prevailing view of the galaxy

(Cosmic 132) The "primordial" black holes have only been theorized; created by the big bang. (Cosmic 110) The Hubble space telescope‚ on the other hand‚ has photographed supermassive black holes.

The changes that occur during a star ’s life are called stellar evolution. The mass of a star determines the ultimate fate of a star. Stars that are more massive burn their fuel quicker and lead shorter lives. Because stars shine‚ they must change. The energy they lose by emitting light must come from the matter of which the star is made. This will lead to a change in its composition. Stars are formed from the material between stars‚ shine until they exhaust their fuel‚ and then die a predictable

Curiosity is a powerful force that drove NASA past the Space Race and never let it stop. After Apollo program ended budget cuts followed; but succeeded with the Skylab project and the Viking Mars Landers but most of all the majestic Hubble Space Telescope. The Hubble Space Telescope lets us watch the expansion of the universe in a way never before imagined. Not only does it have 10 times the resolution of a ground-based telescope and 50 times the sensitivity‚ but another development around the same
