Imagine that out of the infinite stars and planets in the vast universe, only one solitary planet can sustain life. Heavily disputed arguments have arisen about whether humans are the sole intelligent beings in the universe. Scientists continuously search for the answer, but the search has not as yet yielded positive results. Billions of dollars have been spent in research, causing controversy about whether scientists should invest in the hunt for extraterrestrial beings. Due to inadequate technology, humans cannot currently identify whether extraterrestrial life exists, leading to arguments that scientists should refrain from searching for them.

Findings on Earth and other planets suggest extraterrestrial life could live in outer space, further encouraging scientists to proceed with their research. Discovering water is a great step for finding habitable planets. According to new studies, “Mars had a shallow pool of briny water on its surface long ago, NASA said in announcing what could be the strongest evidence yet that the now-dry Red Planet was once hospitable to life. ‘If we are correct in our interpretation, this was a habitable environment,’ Mr. Squyres said. These are the kinds of environments that are very suitable for life” (Bridges). Little evidence proves beings live on Mars now, but this dried up water source provides strong proof that Mars could have inhabited life in the past. Water is a key element of survival, and can also house marine life. Marine life could have simply died out when the water dried up. If Mars was truly inhabited by extraterrestrials long ago, then scientists cannot rule out living beings on any other planet in the universe, and must continue searching.

    The universe, a vast, ever-expanding space full of mystery, just waiting to be discovered. With the mystery comes speculation; a multitude of researchers focus on one question, are there extraterrestrials out there? While highly controversial, scientists with the help of SETI have proved that this is possible. In order to be prepared for the possible ETs, researchers at SETI work constantly to find answers. Because of the growing research that Extraterrestrial Intelligence is possible, SETI, a credible organization, should receive funding from the government to continue their research.

  • "Where is everybody" An exploration of the Fermi Paradox

    2514 Words  | 6 Pages

    Over a 1950 summer lunch at the Los Alamos National Laboratory, the great physicist Enrico Fermi asked his colleagues an unexpected question – “Don’t you ever wonder where everybody is?” Laughter went around the table as everyone immediately knew that he was talking about extraterrestrial intelligence [1]. If life arises fairly commonly, as Fermi believed, it follows that there should be advanced civilizations with the desire to visit and colonize Earth close enough to do so. However, there is no incontrovertible evidence of aliens on Earth, either now or in the past. This is called the Fermi Paradox. The lack of observational evidence for extraterrestrial intelligence is known as the ‘Great Silence.’[13]

    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.

    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.

  • Discovery Of Water On Mars

    1675 Words  | 4 Pages

    With the discovery of water, we can now think about if there is or was life there or in other places in the universe. Stuart Clark, a NASA scientist revealed that the robots on Mars, Spirit and Opportunity, have been able to travel around the planet to the places scientist have detected as wet and taken samples and found that the soil is wet and that the air contains a lot more humidity in it than they thought (Water on Mars). This helps that theory that water is on mars because Earth has a humid atmosphere because of our oceans. The question “is there or was there life on Mars?” Came one step closer to the discovery of water. Since water plays a major key role in life because it contains oxygen, there is a possibility that species could have been able to breathe long ago. We know that there is an Atmosphere on Mars, but it is a very thin atmosphere, so with barely any oxygen, which would mean that the planet is most likely deserted. Things like other If we could get some astronauts that could dig into the planet we could find fossils like we have with the dinosaurs. With a discovery of a fossil, we would know that we are not on the only planet able to make a life. The Kepler Satellite has been searching the universe for a long time and has found over one thousand planets and only one that is like ours, Kepler-186f.

    Mars is one of the most mysterious planet in our solar system. Scientists haven’t figured everything out about Mars, but they do know important facts. The fictional story “Follow the Water”, by Jennifer L. Holm, and the non-fiction “What Would It Take to Live Here”, by Mackenzie Carro, are both two very informational stories about mars. Scientists believe there is a way that living things could live on mars, but there are some factors getting in the way of them being able to know for sure if this theory could happen in the future.

  • The Future of Space Exploration

    1530 Words  | 4 Pages

    With a field as large as space is, metaphorically and literally, there is no end to all the advantages that can come of exploring the magnificent cosmos. One of the major questions we face currently is the possibility of life on other planets. “NASA's biggest ambition is the hunt for life and a habitat that can support life. Several planned or prepared missions will specifically explore the question of whether or not life exists, or once existed, elsewhere in out solar system” (Folger 3). That's exactly what we plan on using the Curiosity rover for. The MSL (Mars Space Laboratory) Curiosity rover was launched November 26th, 2011 and landed on Mars on August 6th, 2012 (Launch 2). “MSL Curiosity's mission is to analyze the climate, geology, and habitability of Mars to see if there is or has ever been life on Mars. Then, after gathering enough data, it will see if it's feasible to send a manned mission to Mars” (Anthony 2). We are already searching ...

    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.
