Persuasive Essay
Life on other planets

How plausable is it that life in outer space exists? Or perhaps, are we alone in the cosmos? Given the sheer enormity of the universe, this question is seemingly unanswerable. However, technological advancements regarding telescopes and other space related equipment are bringing astronomers and scientists closer than ever to finding the answer.

Despite the fact that humans have no proof of life outside of Earth, the majority consensus among many of the leading space-related organizations, such as NASA, as well as many astronomers and scientists argue that life outside of Earth is entirely possible, and in fact, probable. An article on the Dailymail written by Dr. Sara Seager, a US planetary scientist, …show more content…

Seager's claims. At their Washington headquarters, a panel of space program scientists announced their estimation that "Humans will find extraterrestrial life within twenty years". The panelists even went as far as to say that the twenty year estimate was "Conservative". (http://theweek.com/speedreads/index/264761/speedreads-nasa-we-will-find-alien-life-within-20-years, 2014). It is important to note that life by definition, means a "System of material entities that can undergo evolution, which implies reproduction, mutation and selection." (http://www.space.com/27932-life-definition-search-alien-organisms.html, 2014). Many of the general public fail to realzie that astronomers and scientists are not exclusively looking for a alien civilization. At this time, the more plausable life form that is likely to be found are small micro-organizmes that are found in even the harshest of Earth's climates, such as the …show more content…

Scientists will be looking to find microorganisms like these on planets such as Mars, as it is known to have similar vents on its surface. (http://oceanservice.noaa.gov/facts/extremophile.html, 2014). During their meeting, they also outlined their plan to search for alien life and told the media that they would be launching the "Transiting Exoplanet Surverying Satelitte" in 2017. (http://theweek.com/speedreads/index/264761/speedreads-nasa-we-will-find-alien-life-within-20-years, 2014).

NASA outlined its plan to search for alien life, and said it would launch the "Transiting Exoplanet Surveying Satellite" in 2017. Shortnamed "T.E.S.S.", the Explorer-class planet finder will identify planets ranging from Earth-sized to gas giants, by monitoring the brightness of over 500000 stars. NASA calculates that as many as a hundred million habitable worlds in the Milky Way Galaxy alone may be home to extraterrestrial life.

  • Drake Equation Theory

    The biological universe is the idea that our solar system contains life other than ourselves. A question many ask is, “are we alone in this universe?” Formulas, like The Drake Equation, and arguments, like the Fermi’s paradox, have been proposed to help deduce whether our universe is a biological one. The Drake Equation puts forth high probabilities of extraterrestrial life. However, there are skeptics who believe there is only one planet where life can exist, and this planet is the one that discovers us.

  • The Failure Of The Space Race In The United States

    The word race is defined at its core as a competition between runners, horses, vehicles, boats, etc. to see which is the fastest in covering a set course. Well, interestingly enough, a race of a different kind occurred between two countries from the years 1957 to 1969. The competition was unclear, and the opponents were on two entirely different continents, not something as simplistic as two horses. The United States and the United Soviet States of Russia both set out as arch rivals in the “Space Race,” a quest for dominance beyond the known Planet Earth. Ironically enough, just as communism was spreading to all parts of the world, the United States always sought to squash this form of government, despite somewhat dire consequences. Now, with

  • The Human Genome as Evidence of Life on Other Planets

    1221 Words  | 3 Pages

    Since the beginning of human fascination with outer space, the question “Is there life on other planets?” has existed and has waited to be answered. Early astronomers looking to find life on other planets were brutally punished by the Catholic Church. For years, people saw these astronomers as heretics for going against the church and undesirable, but today there might be evidence that supports these astronomers. Today, we find that people are still split between believing in alien life or not. People devoted to a religion tend to disagree with the possibility of life anywhere but Earth as it goes against their beliefs. However, with the increase of realistic movies about aliens and very convincing theories, many young people are beginning to believe that life on other planets does not seem so radical after all. Each day, scientists find more and more predictive evidence that leads most of them to believe that there is life on other planets.

    The existence of life – Aliens, beyond our planet has been a controversial topic for several centuries, and is a debatable issue even today in the 21st century. What is our topic you may ask? Aliens, Do, Exist. According to theoretical physicist, Stephen Hawking, it would be improbable for life not to exist somewhere other than Earth. This is a bold claim, but there is evidence to support this statement. The evidence we seek is in the many Alien occurrences we have experienced throughout human history.

  • Life on Europa

    It is without a doubt that the most fascinating thing about space is the possibility of life elsewhere beside Earth. It is estimated that the Milky Way Galaxy itself contains about 300 billion stars. Each star contains planets and some planets might even have moons. With these findings, the question is no longer whether life exists elsewhere. The probability that Earth is the only place where life exists in the universe is far too slim. NASA has identified many planets that have similar conditions to Earth but most of these planets are hundreds of light years away so traveling there to find out if there’s any living organism is not easy. Luckily, scientific evidences have pointed out that one of the moons of Jupiter, Europa, could be one of the places where life can exist. If the theories proposed by astronomers about Europa are true, life on Europa might not even be entirely different than life near the bottom of Earth’s oceans.

    Colonizing Mars, it seems like a distant achievement. Some say impossible, some say it will happen soon. Since Elon Musk has entered this field of exploration colonization of Mars has seemed even more plausible. Still, problems have surfaced to make this much more difficult than it has to be. This makes some believe this to be impossible or unlikely for the time. Despite what side you are on we can both agree that we want to advance in space exploration.

    Have you ever looked up in the sky and wondered if there is life elsewhere in the universe? Have you ever looked at a photograph of Mars and wondered if there really was ever life on it? People have a wide variety of opinions regarding these questions and with good reason. As far back as the broadcast of H. G. Well's novel, "The War of the Worlds", the world has been fascinated with the possibilities of what Mars may hold. Over time, the majority of people have come to realize that there is no way that life can currently be on Mars. Those who are uncertain think there may be microscopic bacteria underground.

    Recently, two probes were sent back and they made it to Mars. They landed on the South Polar Caps of Mars. That is where NASA plans to find water. After landing on Mars, the probes extracted water like crystals from the surface of Mars. They found that there was a small amount of water in the crystals, which means that there is a strong chance that life, was on Mars at one time.

    One of the most common unanswered questions scientists find themselves asking is "Is there life on other planets?" Since the first famously documented UFO sighting in 1947, the idea of extra-terrestrial life has been debated almost non-stop. The subject has inspired many TV programs, such as The X-Files, and films (Mars Attacks, Independence Day, and the Men in Black films to name but a few). Scientists have come up with many new ideas and ways of trying to either prove or disprove the existence of life elsewhere.

Over the past four billion years Earth has had many rocks blown from the surface of Mars, after much research, scientists say that of the thirty-four meteorites, three have the potential to carry evidence of past life on Mars (Carey, 2006). Researches have gathered evidence and continue to explore for life outside of Earth. Earth has provided these scientists with enough knowledge to understand the components needed to sustain life, therefore any research found is compared to the knowledge already understood about life on Earth. Earth is home to billions of plants, animals, bacteria and all types of living things, it is where human beings have evolved and adapted making this planet our home.
