...Martin Aviles College now 04/16/13 Curtis Assignment: Astrobiology Some of you may be wondering what exactly, is astrobiology? And the answer is simple studying space and even Aliens!!Yes and I believe I know where they might be on a planet not too far from our solar system. One of the possibilities of life may not even be on a planet but on a moon. Saturn which has many moons has one moon that is larger than all the rest Titan; it is the only natural satellite knows to have a dense atmosphere. And the only other object in our solar system besides earth which has clear evidence of stable bodies of water( liquid) to be found. Now what does that mean it means that if we started from our oceans and evolved from there in the near future there might be signs of life. Now I know what you are saying wait how could we live there if life is just begging well we would not, it would most likely be our last resort and we would need a lot of research. And if we did see it as a possible next planet the creature there would most likely look like a lantern fish or some sort of mix of viper fish and angler fish. If life would exist there it would need to breathe methane (stinky farts). The atmosphere on titan is mostly composed of nitrogen and some minor components...

...1. Why are scientists interested in the possibility of life beyond Earth? The discovery of life of any kind beyond Earth would forever change our perspective on how we fit into the universe as a whole, and would teach us much more about life here on Earth. 2. People have long been interested in life beyond Earth. What is different today that makes this possibility seem scientifically reasonable? Today, technology has flourished and is more advanced than it was in the past. We are able to have telescopic and spacecraft photos of planets and large moons, as well as launching missions to further investigate our curiosity. Because of these advances in technology, we know more about the universe than we previously did. 3. What do we mean by a geocentric universe? In general terms, contrast a geocentric view of the universe with our modern view of the universe. Thousands of years ago, many people believed that the Earth was at the centre of the universe; this was the geocentric view. The geocentric view of the universe contrast our modern view of the universe since it is a Sun-centered view. 4. What are extrasolar planets? In what way does their discovery make it seem more reasonable to imagine finding life elsewhere? Extrasolar planets are planets orbiting stars other than our Sun. It is now more reasonable to imagine life elsewhere since many or most stars have planets. Therefore, there may possibly be life living on these planets or moons. 5. What do we mean...

...Arthur Conan Doyle was baffled at these photos. Fairies were considered fake on Earth. He sent the photos to his friend, an expert on photos. A few days later he called him. “Hello.” Said Conan. “Hello.” Said the other person on the line. “Do you have the photos I sent you?” Asked Conan. “Why, Yes.” Said the man. “Do you believe they are real?” Interrogated Conan. “These seem real.” Said the man. “They seem?” asked Conan. “I need much more time to say if their real or fake.” Proclaimed The man. “I will leave you to it” Declared Conan. He hung up. Worried, he knew his friend was an expert on photos and deciding if they are real or not.Would he make him look like a fool, and tamper with them. Anxious Conan called again the next week. His friend then explained “They aren’t fake, there is no strings attached to them and they look very realistic.” The photos were sent back to the two girls with a letter. The letter declared “After months of careful examination we know these photos are real like you have explained to us.” The girls with the guilt overcoming them they decided to tell their parents. ”Mom, Dad the photos we took are fake.” The girls then added “Please do not tell them!” The parents shocked yelled at them “After all the trouble and all the people tricked they are fake!?” . “Yes…” Said the older girl. “How could you!” Exclaimed the parents. “How are they flying then?” Interrogated the parents. The girls explained “We pinned them to the trees and made them look like...

...Carl Sagan's novel Contact is about a girl named Ellie who has a deep passion for astronomy. Her passion for Science comes from her Father who only encourages her to explore more into the universe. Ellie always believed there to be extraterrestrial life and worked throughout her life to discover it. People don't understand her or believe her determination to find what she's looking for. Until the day she received contact from a star known as Vega and is soon to physically experience this journey for herself. In Contact, Sagan's message is received through the different parts that occur in the book although, in the movie many parts were left out getting away from the point of the idea. In the novel Ellie's father died when she was 10 but her mother was still alive. Ellie's mother soon found a new husband, who wasn't very encouraging to Ellie. Ellie's step-father always told her to not seem so smart since she was a girl in order for her to make more friends and to attend these different schools. This is a big part in the message because Ellie proved him wrong by her discoveries even if she was a girl. In the film, Ellie didn't exactly have any push to prove her full ability, there was no person telling her what to do. She simply did it for her passion as well as she did it in the novel but there was more of a personal determination for it. Her mother was a a huge factor because it showed more of who Ellie was and to help her realize how much time she was putting into this...

...1. Assuming scientists came in to radio contact with some type of ETI in 2037 and I was personally offered to answer one question from humankind, being a staff member of the United Nations. If to be true, I would ask, “In terms of environmental stability and living, how does your planetary system and biology functions function?” This is an important question for an ETI because it can bring light into the difference habitats compared to Earth. Comparing the two environments may open ways in improving our environment. 2. In my opinion, the single most serious threat to the survival of humankind over the next two centuries is the true to be told fact that life on Earth is growing rapidly, and resulting overpopulation. It is important for us humans to relieve the shortage of natural resources, such as gas and oil. As we might already know, our economy and lifestyles are really dependent on the two. With limited resources, makes life on Earth quite more serious. As time goes, humans must solve this problem before larger problems result the issue. 3. The Fermi Paradox states, “if civilizations are all common, then the galaxy should have been colonized long ago” (Bennett 454). However, one may argue the that the solution to Fermi Paradox is “we are alone and there is no galactic civilization because civilizations are extremely rare- so rare that ours is the first to have arisen on the galactic scene” (Bennett 454) Works Cited * Bennett, Jeffrey O., G.

...Stardust is the NASA spacecraft that took samples of the Wild 2 comet. This craft returned samples that showed sampled of glycine, an amino acid used to make proteins. The mission took place in January of 2004 and the data was sent back to Earth in January 2006. These results were the first to prove that there are life ingredients in space. This proof restarts the issue of whether our species was created by a meteor or comet that came to Earth and left these similar samples. It’s perfectly logical to think believe if this one comet had these particles that many more could too. That they could be remnants of other planets or celestial bodies even. Dr. Carl Pilcher, Director of the NASA Astrobiology Institute which co-funded the research said, “The discovery of glycine in a comet supports the idea that the fundamental building blocks of life are prevalent in space, and strengthens the argument that life in the universe may be common rather than rare.” This is simply a hint of possibilities for what could be out there. Through this two-year journey much was accomplished. These accomplishments give scientists and astronomers even more of a reason to look into space in search for many things from life to more life ingredients. If our science today can accomplish something like this then the limitations are endless for future scientists and what they can find. Professor Donald E. Brownlee said it best when he said, “The discovery of amino acids in the returned comet sample...

...91415 astrobiology report 2018 Name: Paul Burgess Begin report below this line ESS REPORT What is Trappist 1e: TRAPPIST-1e, is a solid, roughly earth-sized exoplanet orbiting within the habitable zone around the ultracool dwarf star TRAPPIST-1, about 40 light-years away from Earth. The exoplanet was found via the transit method,where the brightness of a star fluctuates due to the occultation of an exoplanet. TRAPPIST-1e is roughly the same as Earth in respect to its mass, density, gravity, radius, temperature, and stellar flux. How do we know these things? TRAPPIST-1e was found via the transit method, in which the planet blocks a small percentage of the central star’s light. This allowed scientists to define the planet's radius at 0.910 R, with a low uncertainty of 166-172 km. Transit-timing variations (TTV) and computer simulations helped calculate the planet's mass, which was found to be 0.772 M. With both the radius and mass of TRAPPIST-1e, it was possible to accurately calculate the planet's surface gravity, density, and composition. TRAPPIST-1e has a slightly higher density than Earth at 5.65 g/cm3, about 1.024 times...

...chosen a research paper titled “Assessing the Plausibility Of Life on Other Worlds”. I have always been extremely intrigued by the possibility of life on other planets and humanity’s’ quest to discover our place in the universe. Previously I believed that these ideas belonged under the disciplines of Astrophysics, Space Exploration or Astronomy but was surprised to find there is a very specific discipline of science called Astrobiology in which this article falls under. Astrobiology is distinct from other space disciplines as it focuses on the actual biology and presence of life and is entirely devoted to studying the origin, distribution, evolution and future of life within our universe. The article is from the peer reviewed journal “Astrobiology” published by Mary Ann Liebert Inc. and has a global audience spanning over 170 countries since 2001. It is published in a monthly style releasing 12 issues annually and targeting an audience consisting of Microbiologists, chemists, astronomers etc. In terms of what ultimately goes into an issue, Astrobiology is under the editorial leadership of Editor-in-Chief Sherry L. Cady (PhD in Geology) who has the final responsibility for all operations and policies but also employs a Managing editor and Deputy Editor who are also senior members with significant input. Apart from this the editorial board comprises of an Australian editor, Asian editor, European editor, sixteen senior editors and forty four general editors all of whom are highly...

...Chapter #1: A Universe of Life? 1.1 The Possibility of Life Beyond Earth What are we searching for? * What are we looking for exactly? * Is it: intelligent life portrayed in sci-fi, more akin to the plants and animals we see in parks or zoos, or is it tiny bacteria-like microbes? * The simple answer to this question is “all of the above” * Extraterrestrial life: Life beyond Earth, we are looking for any sign of life, be it simple, complex, or even intelligent * We have a general definition of what life is, but for now it should be clear that this is a complicated question that affects how we search for life in the universe * Because of the definitional difficulty, the scientific search for extraterrestrial life in the universe generally presumes a search for life that is at least somewhat Earth-like and that we could therefore recognize based on what we know from studying life on Earth Is it reasonable to imagine life beyond Earth? * Prior to the 20th century, for example, some scientists guessed that Venus might harbor a tropical paradise -> this guess was based on little more than the fact that Venus is covered by clouds and closer than Earth to the Sun * Mars was the subject of even more intense debate, largely because a handful of scientists thought they saw long, straight canals on the surface * These canals, which don’t actually exist, were cited as evidence of a Martian civilization * Why has...

...Panspermia The answer to the question: “where did we come from?” has been sought after by mankind for ages. Many different hypotheses have been crafted over the centuries and have been topics of debate for thousands of years; however we still do not have a definitive answer. Types of theories range from those based on religious doctrine to those which take a strictly scientific approach. One possibility that leans towards the latter is the panspermia theory which suggests that life did not originate on earth; but rather came to earth from somewhere else in the universe. It is the idea that the ingredients for life are found throughout the universe and are able to initiate life given a habitable environment. While this theory may seem improbable to some, increasing evidence suggests that this idea may have more truth to it than some may believe. In order for life to have come to earth from somewhere else in the universe, it would have had to survive the harshest environment we know of; space. These organisms would have been exposed to massive amounts of radiation, extremely cold temperatures (nearly -273.15ºC), and extreme atmospheric pressure1. When we think of organisms that thrive in the harshest environments on earth we think of extremophiles, and perhaps the most renowned and complex extremophile is the tardigrade. These dry aquatic invertebrates are known to be one of the most resilient species on earth and have received a lot of attention from researchers regarding...

...Dinosaurs and the Bible There is widespread controversy about dinosaurs: When did they roam the earth? Did they coexist with humans? Why did they go extinct? These are common questions that evolutionists and creationists alike try to explain. In the article “Dinosaurs and the Bible” Ken Ham tries to explain biblically these common questions about dinosaurs. He explains that in the school systems today, we are taught that dinosaurs lived millions of year ago and went extinct before humans were even on the earth. Ham then refutes this by explaining that dinosaurs did in fact exist with humans, and using the bible as his reference proves his point. According to the language of this article, it seems that this article is aimed at a reader who isn’t knowledgeable on the subject. He uses simple language, and gives additional explanations for certain concepts of evolution, and ideas that he uses. This aids in the comprehension of the beliefs that Ham proposes. Ham certainly proves his credibility throughout by giving multiple scripture passages, and using the evolutionist theories to strengthen his statements. He clearly explains his beliefs in a convincing way. He also raises many common questions, and then gives a logical answer that fits perfectly with his ideas. However, there could have been more counter arguments to further back up the statements made by Ham. In the conclusion of the article, Ham gives the gospel message, which could possibly be viewed...

...EARTH PERSPECTIVES The biological and geological future of the Earth can be extrapolated based upon the estimated effects of several long-term influences. These include the chemistry at the Earth's surface, the rate of cooling of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity. An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans, such as geoengineering, which could cause significant changes to the planet. The current biotic crisis is being caused by technology and the effects may last for up to five million years. In turn, technology may result in the extinction of humanity, leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes. Hawking: How Humankind Will Survive the Future Listen, people of Earth: Everything's going to be fine. All we have to do is survive another century or two without self-destructing as a species. Then we'll get off this rock, spread throughout space, and everything will be all right. If this is not your idea of "optimism," then you are not Stephen Hawking. The esteemed physicist garnered headlines, and some eye-rolls, after telling Big Think last week that humanity needs to leave the Earth in the future or face extinction. As The Atlantic noted: He's not knocking climate scientists' attempts to figure things out on Earth-he's just thinking long...

...LIFE IN THE WORLD 3.1. The nature of life according to Christianity Christianity teaches that the universe was created through love by an intelligent power, namely the God of the Bible. Creation was purposeful, not arbitrary, and therefore the universe is not morally neutral, but fundamentally good. In this purposeful creation, everything and everyone are intrinsically valuable. God's design or purpose for creation reflects God's intention that all creatures enjoy perfect love and justice. God works in human history to fulfil that purpose. God created human beings in the divine image, enabling humans to have some understanding of God and of God's vast and complex design. The purpose of life is to love and serve God in order to help bring about God's glorious plan for creation. Reason is a unique gift bestowed by God on humans and enables them to reflect on their own nature and conscience, and from that derive knowledge of God's will for creation. But a complete understanding is beyond human reach. To fulfil the goal of wholeness in an existence perfected by both justice and love, something more is needed. Humans are not expected to accomplish the divine plan alone. The fulfilment of God's purpose depends on God's grace. For Christians, grace is God's freely-given favour and love. Reason is a good gift, sometimes misused for selfish, wilful, or prideful purposes. The substitution of selfish ambition for God's will is a condition that Christians call sin, meaning separation...
