life beyond earth essay

ABSTRACT In this paper, the great dispute of whether or not there is real evidence of life on martian meteorites is discussed. Findings of carbon globules, nanocrystal magnetites, and rod-shaped objects on ALH84001, Nakhla and Yamata 593 suggest biogenic processes once occurred on Mars. Furthermore, past atmospheric conditions and a current abundance of methane gas build more justification to martian life. Many of these discoveries are accused of being accounted for by either terrestrial contamination

being life beyond earth. Green starts off with a quote that is used in a lot of movies, books and television shows, “Is there life beyond earth in our solar system?” He follows this initial quote with one by Carl Sagan, an American astronomer, “It takes extraordinary evidence for extraordinary claims.” It is important for Green to use these two quotes as attention getters. He hooks the listener with his works and we begin to think if there really is life in our solar system then just on earth. It

“The Earth is just too small and fragile a basket for the human race to keep all its eggs in” (Pournelle 170). If a fatal catastrophe were to occur on Earth, the human race would cease to exist. While the chances of this happening may not be particularly worrisome, it has happened before. Such an event is exactly the reason dinosaurs no longer rule the world. Even without external forces acting upon us, we have already created potentially devastating and irreversible effects ourselves. Pollution

with the current political situation, it may be a possibility however within such eerie vision lies the possibility of change, and that it is not too late to change the direction we are currently headed in. As hooks states in Earthbound, “To tend the earth is then to tend our destiny, our freedom and our

by a child at play. The feeling of going back and forth gives one the feeling of leaving earth for a little while and soaring above the trees. Feet towards the heavens and the feeling of one’s stomach dropping on the way down, gives a sense of release. As one goes through hard times, they look for that release from the world. The desire to get away is released through swinging to then be pulled back to earth. This same feeling was felt in Birches as a young boy rides

of Life,” written by Henry Wadsworth Longfellow and chapter 39 of the book of Psalm in the Bible share many similarities as they both give advice on how to live one’s life. However, there are several differences in the two. In “A Psalm of Life,” the author wants to send out the message of not to live life in pursuit of death, but rather embrace every moment of it in pursuit of happiness. Although heaven maybe the ultimate goal in the end, we should all work to live life to the fullest . Life does

happiness is distinct from this, both in what it entails and how it is achieved. Aquinas believes that humans cannot be entirely happy until fully understanding God, the original cause of their own being, which is impossible until reuniting with God in life after death. Humans cannot be truly happy until their intellect is fulfilled, which is only possible through understanding God. The human intellect instinctively seeks to understand the cause of things, and will not be satisfied simply knowing that

Throughout history humanity has been fascinated by the existence of extraterrestrial life. Today such ventures are in the development process and the discovery of life beyond our solar system, no matter how primitive, may soon become a huge(important?) scientific breakthrough. The three basic things that are required to consider a place even remotely habitable are water, a source of energy, and organic materials. Habitability also depends on other factors that must also be taken into consideration

were the freedoms to explore beyond the Earth’s surface. While, in the civil rights movement, the freedoms were to seek freedom from oppression and discrimination. Regarding the space race, the advancements, trials, and efforts put into programs and tests were all for the goal of expanding human knowledge and access beyond the surface of the Earth into the commonly seen, but completely unknown space that encapsulates the Earth. The space race sought to explore beyond what is known and be free to

“Wild Geese” is an inspiring message to help remind people that they are not alone on this earth and their problems are small in the grand scheme of life. The narrator does accomplish the difficult task of self-improvement in a non-aggressive way. In the beginning if the poem, the tone is a little condescending when the narrator is discussing the necessity of letting go of the problems in life and not basing life on these challenges. The poem is not insulting, though one of the main topics is on getting
