Recommended: Argumentative about life on Mars
Over the years, scientists have wondered whether the Earth is the only space body that is capable of sustaining life. There is evidence to support both theories, but we still don't know for sure that we are not the only kind of life out there.
There are different space bodies that are most important to have life in them; some of these places are Mars, Europa, Titan, Enceladus, and Ganymede and Calysto. One of the main reasons why scientists strongly believe that there is a good chance of life in Mars is because there is sufficient facts to imply that it had running water on its surface millions of years ago. There’s also evidence that ice and water existed on this planet. This evidence supports scientists who believe that life existed at some point on Mars. This data was discovered when the images taken from the Mars Reconnaissance Orbiter captured some characteristics of the planet's surface. Scientists believe it was created by the melting ice. Also in May 2009, images of an unmanned spaceship showed what it seemed to look like drops on the surface that appeared to be built during the time of the mission of the spacecraft on Mars. Another place that has scientists believes life is a moon of Jupiter, Europa. Some of them believe that there is a giant, active salty ocean beneath its surface. This indicates that there is significant activity underneath that frozen surface. Another sign of life in Europe includes formations that looked like icebergs emerging from its surface, suggesting that oceans once covered the planet before it froze. The third space body where scientists think there is life is on one of Saturn's moons, called Enceladus. There are images taken by the Cassini spacecraft orbiting Saturn, proved that there are ice ...

While there are many reasons to believethat there islife on other planets, however, there are some reasons that explain how extraterrestrial lifewould not be even possible. One of these arguments holds that extraterrestrial life should be very rare due to the time it takes for life to evolve is much longer than that of the existence of a star. Other reasons are that some planets in our solar system are eitherwaytoo hot orway too cold for life, and in some of them rains different kind chemicals, therefore, is potentially unlikely to life to exist on these space bodies.
From my own point of view, I believe that there might be life on other planets. It may or may not be intelligent life, but life nonetheless. With evidence of water ice in the space bodies mentioned above there is a good chance that there could be life in those places.
Finding life in our solar system could potentially answer the questions humanity has been asking for thousands of years. Sarah Seager, a professor at MIT, mentioned some of these thought provoking questions, “why are we here? Why does our universe exist? How did Earth form and evolve? How and why did life originate and populate our planet?” Answers to these questions could give humanity a deeper understanding of who we are and what our place in the universe is. Steven Dick believes that humanity has “… deep psychological yearnings for companionship, superior wisdom, or ‘an ineradicable desire to see the skies filled with life’.” Those opposed may argue that a biological universe will have little effect on humanity’s understanding of our place in the universe because a biological universe simply does not exist. One may argue that life is exceedingly complex and the odds of conditions being just right for the production and the sustainment of life are slim. Our civilization may have managed to beat the odds, but many its unlikely to for this to occur elsewhere in our solar system. The proof to back this argument is the N =1 equation. The only solid evidence we have proves that only one planet has beaten these insurmountable odds and produced life. While this argument makes logical sense, relying solely on evidence we have at the moment, takes our focus away from the
Since ancient times humans have been trying to understand our place in the universe. The big question many ask is “are we alone in this universe?” Formulas and arguments like The Drake Equation and Fermi’s paradox have been proposed to predict and answer questions like this. Many scientists believe life exist in our galaxy other than us based on the high probabilities The Drake Equation puts forth. However, there are skeptics who believe the one equation to rely on is the one that validates that there is only one other planet in our solar system that has intelligent life and we live in it. Whether life outside of Earth exist or not, exploration of the idea of a biological universe is important for humanity’s understanding of our place in the solar system.
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.
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.
Tracy K. Smith’s “Life on Mars” is a collection of poetry dealing mainly in the search for a sense of purpose and the nature of people. The books is something of an elegy as a whole with many poems pertaining to death and the author’s struggle with the loss of her father. The poems are at once poignant and gentle in tone and leave questions than can only be answered in multiple readings. The book is segmented in four parts that travel through different topics and types of poetry. The mood ranges from passionate accounts of Orwellian politics to soft recollections of a lovers embrace; throughout the book Smith brings in references to pop culture, science, and technology that incorporate seamlessly with her words.
Can the Earth be the only place in the Universe that harbors life? Most astronomers don't believe this is true. Certain statistics in the Universe provide evidence that living beings may be common place through out the universe, on planets of other stars besides the sun. In this paper I plan to discuss the various viewpoints of those that believe that extraterrestrials exist and have even been visiting Earth, and the viewpoints of skpetics that believe that aliens don't exist and have not been visiting Earth.
Since the 18th century speculation of unearthly life has been brought up by many influential people. One of the founding fathers of the United States, Benjamin Franklin, once stated "I believe that Man is not the most perfect Being but One; rather that as there are many degrees of Beings his Inferiors, so there are many degrees of Beings superior to him”. This quote justifies the fact that even the most prominent people believed in cosmic beings. Further in time, In July 1947, an unidentified flying object crash landed in a ranch near Roswell, New Mexico. What military officials discovered was nothing more than the debris of a weather balloon that was being tested. However, people did not seem to fathom the truth and began to investigate what the military did not want the public to know. Bodies of unknown humanoid beings were seized by the military and taken into a secret base for further analysis. Various reasons as to why celestial beings could lurk the universe are being brought upon by today’s modern science committee possibly unlocking an insight onto future life. The first reason as to why extraterrestrial life could perhaps exist is that there is a vast amount of galaxies, stars, planets, and solar systems that humans have not yet discovered. To think that humans, the only civilization on planet earth, are the only living organisms in space would be quite absurd. Furthermore, a second reason as to why extraterrestrials could subsist is that life thrives in the most extreme conditions. This means that whether organisms are in the depths of the ocean, in the midst of the ozone layer, or in the scorching hot temperatures of volcanos; life always finds a way to adapt. However, some may argue that life could not possible coin...
Another argument for the existence of life on other planets is the phenomenon of extremophiles! These orgasims are a type of living being that can thrive under high temperature and pressure. Some can even survive without oxygen. Lots of these extremophiles are found at the bottom of the ocean near hydrothermal vents.(http://oceanservice.noaa.gov/) And the best part is we are finding new extremophiles. It wouldn be crazy to think that we actually might be able to find this type of organism on some other planet or
Scientists have dreamt over the possibility that it may be possible to live on another planet. Some think that Mars has that potential to support life, if it's hidden resources are uncovered and exploited to their full potential. There is even evidence that it once contained enough water that it had been possible to hold life. Think about it, what if we could transform it into such a place, even if only our children's children get to see any result? The following will describe Mars, present evidence of ice and water, give possible ideas for the future exploration of Mars, and give reasons for why it is important.
Is there such thing as life outside of Earth? The building blocks of life are carbon, nitrogen, and oxygen. Those ingredients condense to form all living things, new stars and even new planets! So, who’s to say those ingredients didn’t form other life on other planets? Think about how vast outer space is. There are millions and millions of other planets, stars and galaxies! It’s not that far out there to think that there might be other life in space, in fact, some people even have stone hard evidence that supports the idea of “aliens”. I personally believe there is such thing as extraterrestrials, and I believe they have visited earth before. As a child, I remember my dad and I would sit around all afternoon watching alien documentaries or shows about people hunting aliens and searching for UFOs. When it comes to aliens people have so many questions; have aliens been to earth before? Are they currently living on earth? Are they controlling us? Does the government know? If so, are they hiding it from the public? There are so many questions you can ask but, in order to answer them, you have to
Trillions of habitable planets, those that can sustain liquid water, exists in the universe. From looking at the number of habitable planets that exist, there should be other life forms in the universe and out of these life forms, there should be intelligent civilizations. When looking for alien civilizations, researchers look at the planetary bodies within our local group. Everything outside the local group is unreachable because the universe is always expanding.1 “If only 0.1% of those planets harbored life, there would be 1 million planets with life in the Milky Way.
Should we as humans expect to find intelligent life elsewhere in the Universe? There are many reasons for and against this concept, but first we should trace just how our terrestrial life started.
I feel there must be extraterrestrial intelligence. Even if not in our galaxy, in the universe somewhere. Someone once said, "Absence of proof, is not proof of absence." I think he is correct. While we do not know that aliens exist, we do not that they do not exist. Considering the many UFO sightings, most of them are probably conjured, but at least one had to have really happened because the idea is too crazy to be thought of out of nowhere. Some scientists argue that the chances of alien intelligence are slim since the circumstances that produced life were all just strange coincidences, all the same circumstances happening somewhere else is extremely unlikely. I think it is just arrogance to assume we are the only intelligent life in the universe.
Statistics have showed 7.5% of rocks from Mars reached Earth. These rocks would travel between less than 100 years to 16,000 years and more to get to Earth. Some proponents include Gyon de Montlivant, who proposed that life came from moon, H.E. Richter, who suggested life came from meteorites or comets, but Svante Arrhenius proposed this theory.
Mars is a very similar planet to earth in relation to size and atmosphere. Therefore it seemed like the most likely place to search for life. At the end of the 19th century, an American named Percival Lowell built himself an observatory so that it was possible for him to study Mars in intimate detail when its orbit was closest to Earth. At this time it had recently been suggested that the planet had a system of channels on the surface, present from the evaporation of flowing water. Looking through his telescope Lowell became convinced he could see a network of artificial canals. This led him to believe that there were intelligent beings on Mars who had built these canals. However, spacecraft have now visited Mars and found that there is no evidence of water at all. It is now thought that the lines he could see were the combination of Lowell's overactive imagination, and scratches on the lens of his telescope. We are now searching one of Jupiter's moons, Europa, as this seems to be the next likely place to hold life.
