Astronomy Research and the Search of Extraterrestrial Life Paper Megan Lade University of Phoenix (Online Campus) Christopher Conner All life on this planet is linked to the geology of Earth‚ and vice versa – we (all organisms) are supposed to be living in a symbiotic relationship with our world. When Earth was developing deep within its curst began the first traces of raw materials and minerals that would fuel life for many years to come. We adapt and change to our ever

Search for Extraterrestrial Life Introduction Mankind has always wondered‚ "Are we alone in the Universe? Isn’t there life out there somewhere?" With an estimate around 300 billion stars in the Milky Way galaxy alone‚ many with their own satellites‚ the possibilities seem likely that some form of life should exist somewhere in the Universe. This search for life begins with a definition of life itself‚ followed by possible candidates both within and outside our solar system‚ and also includes

and night to answer that very question through experimentation and research. In the years since‚ the search for extraterrestrials has fallen under various names and has been taken control of by several organizations and people. In 1982‚ Carl Sagan‚ an American astronomer‚ cosmologist‚ astrophysicist‚ astrobiologist‚ and author wrote a letter directed to the Science community suggesting the idea of searching for evidence of other life forms amongst us in the universe. This letter was signed not only

Humans have always been wildly fascinated about the possibility that extraterrestrial life could‚ does currently‚ or has existed elsewhere in the universe. This is a subject that has been questioned by humankind for at least 2000 years. Lucretius‚ a Roman poet from the first century B.C.‚ had suggested that “just as life originated by spontaneous chemical interactions on Earth‚ ‘we must acknowledge that such combinations of other atoms happen elsewhere in the universe to make worlds such as this

A Cyclic Universe: A New Model to Rival the Big Bang Theory Phys 1070- Astronomy Topical Essay Motivated by the M-theory‚ space-time ‘branes’ and extra-dimensions‚ scientists Paul J. Steinhardt and Neil Turok introduce a tantalizing alternative to the prevailing standard Big Bang-Inflation model of cosmology. Traditionally‚ the Big Bang-Inflation model features an explosive epoch 15 billion years ago when time and space sprung into existence followed by a fraction of a second of superluminal expansion
