The Search For Extraterrestrial Life Essay

The Search for Extraterrestrial Life Essay
Abstract: Scientists claim that other life forms do in fact exist based on probability. The conditions necessary for life are likely to be present on
various other planets. Signs of possible life have been found in material from outer space. Much research has been dedicated to proving the existence
of life on Mars. SETI is a program entirely dedicated to finding and establishing communication with extra terrestrials. If other life forms are found,
communication with these beings will be a difficult task. Laws to protect humans from the dangers of extraterrestrial beings are already in effect.
Although contact with alien beings has not yet been made, technology today may make it a reality in the near future.

Among the billions of stars in each galaxy, many have planets that revolve around them. At least a few are bound to be of the right size and have the
correct spatial orientation with respect to their star to allow life to grow. We believe this because life exists on the Earth. Astronomers have concluded
that there must be hundreds of billions of other stars with conditions approximating those of the sun. Therefore there could be a million earth like
planets with advanced civilizations in the Milky Way galaxy alone (Stilley). It is very probable that there is intelligent life elsewhere in the universe.
Most astronomers and scientists seem firmly convinced of this fact. Although there is not any direct (or even indirect) evidence to support these
claims that other sentient life is sharing the universe with us. However, this lack of evidence showing that extraterrestrial life forms exist is not proof
that they do not exist. It just does not seem logical that our planet is the only place where life and intelligence could have developed. The odds are
billions against life of some form being unique to the Earth only. The Earth is unimportant in the grand scale of things in the galaxy. By this I am
referring to its' size and position in the universe. In fact, the American Association for the Advancement of Science suggests that the true question that

Extraterrestrials
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.
To get into the topic we must first start at the base of the subject. First the question must be dealt with of life being only indigenous to planet Earth. One

According to some scientists Mars our sister planet may have started to harbor life early in its evolution but some catastrophic event caused Mars to
become the barren frozen wasteland it appears to be today. for our solar system alone 2 out of 9 planets that have or may have had life aren't very bad
odds for extraterrestrial life throughout the Universe.
Most skeptics of extraterrestrial life or at least of intelligent extraterrestrial life existing are those that believe in Creation rather than evolution.
Creation, in Christianity states that in seven days the Sun, Earth, and all life on Earth were created by a superior spiritual being, or God. This paper
was not written to argue whether any of this is true, or debate the existance of God but just states the opposing views of those who believe intelligent
life is non–existant elsewhere in the Universe.
I believe that the human race would very much like to feel that we are the only intelligent life forms in the Universe. To believe that we are the only
intelligent life forms in the universe makes us feel special and gives our life a purpose that no other being can experience. To have proof of other
intelligent life existing would give humans such a cultural shock that some have said that our social, economic and political systems would be thrown
off balance.( Cornet, 1995, paragraph 10) Religious, and social chaos would become rampant.
To wrap up the question

The Existence Of Extraterrestrial Life
Unidentified Flying Objects or UFO sightings have exploded into a worldwide phenomena, but still there are many people who refuse to believe that
extraterrestrial life exist. It is hard for some to wrap their head around the idea of little green men from outer space being more advanced in space
travel than humans. The earliest UFO sightings in recorded history can be found in 4th–century Chinese texts claiming that a "moon boat" hovered
above China every 12 years, and ever since people have been claiming to see or be abducted by UFOs ( M.J. Stephey). Aliens exist because of the
amount of planets that can support life, UFOS have been seen all across the world, and there is a FBI agency dedicated to covering up the existence of
extraterrestrial life.
The fact that NASA has spent years searching for planets that could support life makes people wonder whether there could be life already out
there. In 2009 NASA launched the Kepler space telescope hoping to find as many habitable planets as possible. Kepler has found over 1000
exoplanets and confirmed that twelve are within habitable zones. Scientists look at many factors to determine in a planet can be habitable: how close
it is to its host star, if it has an atmosphere, and if the planet has traces of water (Mike Wall). After 15 years of research NASA announced the
discovery of water on Mars. Scientist believe that the red planet could of been covered in oceans at one point in time, but over time the water
evaporated (Nola

Does Life Exist On Other Planets? Essay
Does life exist on other planets? There are many people who both believe in, and don't believe in the existence of extraterrestrial life in the universe.
While the people who don't believe that life exists on other planets so have some decent arguments, the universe is so vast that it is possible there are
other Earth–like planets capable of supporting life. It is highly probably due to the vastness of the universe and the many Earth–like planets we've
already discovered that are possibly capable of being a host for life. One prime example is the recently discovered planet Proxima b. A recent
discovery has uncovered the planet Proxima b, which is a planet with a rocky surface, and an exoplanet, which is a planet that orbits a star out of the
solar system, that orbits Proxima Centauri, which is the closest star to our sun. Proxima b, as far as researchers know, is most likely the closest
exoplanet to us in the universe. Proxima b is only about 4.2 light–years away from our solar system. This is about 266,000 times the distance between
the Earth and the sun, which are around 92.96 million miles. In the past, other rocky exoplanets that we've discovered, such as those orbiting the red
dwarf star TRAPPIST–1, have been considered close to us at around 40 light–years away, which is obviously much, much further from us than Proxima
b. Proxima b has many suitable characteristics for life that we already know of. It is about 1.3 times the size of our Earth, it orbits its star about

Exoplanet TRES 2 Research Paper
This experiment was conducted to study and investigate if extraterrestrial life exists upon the exoplanet TRES 2. It was hypnotized that TRES 2 did not
sustain the qualifications to support extraterrestrial existence. The results from this testing conclude the hypothesis was correct, with research as an
addition from the luminosity testing it has been knowledge that TRES 2 reflects less than 1% of light making it one of the darkest exoplanets currently
discovered. Light is a crucial element in the building blocks of life, it is the most important factor that influence the way life evolved on Earth. From

In the present day, Earth is the only example we have of a planet with life.When approaching a topic such as extraterrestrial life, religion and science
continuously have a dispute. Throughout history, with limited access to scientific instruments or equipment, people who believed in life beyond earth
were in minority. That is why a debate aboutextraterrestrial life was rather limited before. However, in our modern society, more and more people
develop an interest in this topic. With today's ability to travel to space and access to diverse types of machines, scientists are able to entirely dedicate
their everyday life to find and establish communication with extraterrestrials. Although a very large percent of people are against the belief...show more

Since the year 1960, a group of astronomers and scientists have dedicated themselves to the Search for Extra–Terrestrial Intelligence (SETI Institute).
Astronomer and astrophysicist, Frank Drake, most notable as one of the pioneers in the search for extraterrestrial intelligence, including the founding
of SETI. Drake invented The Drake equation, it is a probabilistic argument used to arrive at an estimate of the number of active, communicative
extraterrestrial civilizations in the Milky Way galaxy. Although this equation is not an accurate way to estimate the number of communicating worlds,
it encourages radio astronomers to keep listen and analyzing the signals from intelligent extraterrestrial life. Every day astronomers are listening for any
kind of radio waves that could indicate another world trying to contact us. The only impediment to this is that if a civilization exists, the nearest one to
Earth might be thousands of light years away. Communicating would take a long time and the radio wave might not reach its destination because of
the estimated distances from one civilization to the next. {in progress and need to include

The Pros And Cons Of Extraterrestrial Life
One of the most prominent and controversial topics related to astronomy is whether or not there is life outside of our planet. This isn't necessary an
issue, but rather a question that has confounded me my whole life and what initially inspired me to take this class. This question has driven people to
question our place in the universe all throughout history, and as best said by Neil deGrasse Tyson, "The time–honored question: "What is our place in
the universe" might just be genetically encoded in our species" (Tyson, 2003). Personally, I think it is ignorant to assume we are the only living
intelligent life in our universe due to its vastness and endless possibilities; however, research hasn't proven much yet.
To begin, I want to first define extraterrestrial life, as there are many definitions and part of what contributes to extraterrestrial life controversy.
According to Nola Taylor Redd in the articleSETI & The Search for Intelligent Life, extraterrestrial life can roughly be categorized into two groups:
the first category is life itself, which includes microorganisms and other simple forms, and the second group includes intelligent life. Intelligent life can
simply be defined as life forms that originates anywhere outside of Earth; however, this definition still feels a little broad and doesn't exactly provide a
clear idea of intelligent extraterrestrial life. In the article Extraterrestrial Intelligence: Hypothetical Life Form, Seth Shostak defines extraterrestrial

Argumentative Essay On Aliens
What do dishwashers, music festivals and Iowa have in common? They are all places where you can't find aliens. Well, maybe in Iowa, but according
to Harvard, they have a specific place that NASA should be searching for life. Not surprisingly, it's in space.
HARVARD SAYS ALIENS MAY EXIST IN THE MILKY WAY
A leading astronomer has said that aliens are living in giant star clusters on the edge of our Milky Way, andNASA should be able to find them. These
groups called "globular clusters", have been around nearly twice as long as the Sun and Earth. Considering that's a pretty long time, this means that
aliens found there could have evolved to be far more advanced than humans. This isn't just microorganisms we're talking about. Think more along the
lines of the Earth dominating kind of alien. This bold claim has been made by Harvard professor Dr. Rosanne Di Stefano in her article about star
clusters. Now, NASA just has to find a way to those star clusters in order to prove her right.
ANCIENT STARTS HOLD THE KEY TO LIFE

Apparently, the stars in this region are so close together that it would take just a month to travel between them. Picture a supergroup of rag–tag space
explorers, star–jumping, time traveling and battling hostile aliens.I believe Steve Buscemi has already signed up for the mission. With a group of stars
this close, it would certainly be easy to set up multiple civilizations out there. At the moment, only one planet has been identified. The 12.4
billion–year–old Methuselah is an exoplanet that shows some potential. Of course, nothing is known for sure, but if one were to search for aliens, a
cluster such as this would be the best place to

Essay about Intelligent Extraterrestrial Life
Intelligent Extraterrestrial Life
When I look up at the stars at night, I just have to wonder who or what is
looking back at me from some distant planet in some distant galaxy. We've all
probably wondered what lies beyond our small, self–contained little world. The
question many have pondered is whether or not there is intelligent life beyond
earth. In the words of Metrodorus, a Greek philosopher of the fourth century,
"To consider the Earth as the only populated world in infinite space is as
absurd as to assert that in an entire field of millet, only one grain will
grow." I believe that intelligent extraterrestrial life does exist.
Critics of the theory of intelligent life beyond earth will argue that there is...show more content...
Some say that there couldn't possibly be life on other planets because other
planets are too harsh to support life. First of all, our galaxy contains about
100 billion to 200 billion stars (Angelo 1985). Each one of these stars could
have planets much like ours, with an atmosphere capable of stabilizing an

environment to a point in which life is suitable. The only reason some think
that there are no planets like Earth is that we have actually explored and
researched very few planets, only a small fraction of the entire galaxy. In
addition to that, scientists believe that our galaxy is a very small fraction of
the universe. A universe which is still expanding, and will continue to expand
forever (ScienceNews May 29, 1999). The number of possibilities for life is
literally infinite.
Before we can discard the notion of extraterrestrial intelligence, we must
consider how much we actually know about the universe around us. While
scientists are fairly sure that no intelligent life currently exists on mars,
the possibility of past intelligent life is still unknown. A two year
investigation of a meteorite found in Antarctica, and believed to be hail from
Mars suggests that life did exist on Mars about 3.6 billion years ago. While
discussing the analysis of this meteorite, Richard N. Zare of Stanford

The existence of extraterrestrial life has been a popular topic for several years. Some creatures from other planets occurred in the fantasic movies.
Although some scitientists believe that extraterestrial life does not exist in the real world, I think allians exist in some other planets for two reasons.
First reason is that we cannot observe extraterrestrial creatures now because of the limitation of current technology. Although some people think the
technology developed in a high level, there are still a lot of unknown things to us because we cannot explain or prove them. With the improvement of
the technology, people might find out extraterrestrial lives through modern equipment. Another reason why I support my statement is that some
observations

Introduction There is no one universally accepted paradigm for the origin of life. Rather, there are two competing schools of thought that debate the
question: Was the origin of life terrestrial or extraterrestrial? Both of these theories recognize that life must have been synthesized under natural
conditions, that molecules organized themselves into the first molecular system, that atmospheric oxygen and ozone were rare, and that electrical
activity may have produced monomers. The scientific and technological advancements that have emerged as a result of investigations into the origin of
life have profoundly impacted our society and our knowledge of life, space, and cosmochemistry. Early Emergence of Cosmochemistry and
Sociopolitical Hindrance The list of cosmic abundances was compiled by Victor Goldschmidt in 1938 and concluded that "Extraterrestrial material must
also be included to produce the most accurate and robust data" (Citation). The template for life remained unknown to society, so a broad approach to
include both terrestrial and extraterrestrial sources was imperative to the investigation into the origin of life. Unfortunately, the Great Depression
diverted society's attention towards surviving through the low living standards, so there was an overall disinterest in anything scientific. Although
World War II lifted society out of the Great Depression and brought many scientific advancements related to warfare, no breakthroughs in interstellar
science and

Alien Life Research Paper
At some point in our lives we have gazed up on a clear, crisp and starry night sky and wondered and asked "are we alone?"
As an amateur astronomy I can say I have not seen anything that cannot be explained, so I would say I am certain no alien life force has visited
planet Earth. There will be people 'conspiracy theorists' mainly who believe there is a major worldwide cover up, there will be some religious groups
who believe we are made in their Gods image and that alien life would not exist another worlds.
However the universe is vast and the possibility of no life out there is pretty remote. If life can emerge on one celestial body, then surely it will evolve
on other worlds given the right set of circumstances.

This is done when such a body passes in front of its parent star, from our prospective. Light from the star interacts with different molecules in a
planets or moons atmosphere. From this type of researches we can narrow down where to look for life.
Another method is sweeping the sky for signals, much like what SETI does now. The downside of this method is are we listening in the right place,
and are we tuned in to alien signals?
So this brings me to the point of the article. It has just been announced in the past couple of days that Russian Billionaire Yuri Miner wants to invest
$100 million in the hunt for ET, and Professor Stephen Hawking, the brilliant physicist backs the idea along with SETI pioneer Frank Drake.
Hawking states "Somewhere in the cosmos, perhaps, intelligent life may be watching these lights of ours, aware of what they mean." He also says "or
do our lights wander a lifeless cosmos–unseen beacons, announcing that here, on one rock, the universe discovered its

Over the years there has been questions that people are asking if we are alone. Scientists have been seeking evidence of extraterrestrial life in the past
half century. There have been many sightings of unidentified flying objects (UFOs) seen by the people around the world. Scientists state that intelligent

SETI thinks that the signal will be received at or frequency of 1420 MHz, to detect a strong signal. SETI believe that a signal received from such a

Scientists Wonder Why Alien Have Not Visited Us.
A young director of the Green Bank National Radio Astronomy Observatory in the USA name Frank Drake set up the first systematic search for
extraterrestrial signals called Ozma. In 1960 it spent two months looking for radio signals in the directions of two nearby stars, Epsilon Eridani
and Tau Ceti, which is twelve light years away from us. During this experience, they had zero results of extraterrestrial signals. In 1940, was the
first sightings and reports of UFOs in the USA. In 1950, an Italian physicist Enrico Fermi had a discussion with his colleagues of civilization in our
Galaxy. Fermi concludes that aliens already have visited, but had no evidence to prove this theory. In Fermi paradox also believes that the probability
of appearance of intelligent life is weak because Earth is the only one in the Galaxy it occurred. Aliens don't seem to be walking our planet apparently

Any discussion on this conspiracy, however, will not be complete without talking what went and goes on in Roswell, New Mexico, or better
known as Area 51. Area 51 is known to be a US Military Base where 75 miles away, there reported to be a UFO crash landing on July 2, 1947 that
left an exceptional amount of debris all over the area. The Roswell Army Air Field reported that they recovered a "flying disc" but a few hours
after this information was released, the government immediately said it was a "weather balloon." RAAF even reported having recovered alien
bodies but as expected, the government denied again and simply stated that it was the military men's trauma from accidents. Countless witnesses
during and after the reported crash date have confirmed seeing flying objects, crop circles and usual activity within the area. Area 51 is now
conspired to be a place where they examine evidences of alien bodies, UFO crashes, etc, but the government refuses to confirm and have denied
these allegations. More than sightings, as promised, let me take you in on one of the craziest abduction stories. There have been over 60,000 reported
abductions worldwide. In most cases, the victims are returned but don't remember a thing. And in some, the victims are lost forever. The story I'm
about to tell you is one of the most bizarre ones ever recorded. So bizarre that it took more than ten years to be able

Extraterrestrial Life Or Alien Life
For a long time, there has been a dispute on whether or not extraterrestrial life or alien life exists. The discovery may not be in the near future, but it
is more than likely to happen. Someday we might be able to identify a planet and say that it is just like Earth. Finding life outside of Earth is within
reach. Extraterrestrial life is not a myth and there are many reasons why such as evidence from National Aeronautics and Space Administration (NASA
), discovery of Earth–like planets that orbit a sunlike star, and discoveries on planets closer to Earth. Many scientists believe that we are one of many
species in the universe that exist on more planets than just Earth. It would be silly if someone did not believe that there is life on some of the billions
of planets to exist in our galaxy alone. NASA has found evidence of another potential solar system. This is a collection of stars orbiting around a single
star and is located around 39 light years from Earth. Nasa's telescope team said it had found a system of seven planets that were all similar in size to
Earth (Gaffey). The planets formed farther out from Trappist–1 and then moved inward. This makes it more likely that they could contain some form
of water. Volatile compounds (molecules that easily turn to gas) like water are usually concentrated further out in star systems. The fourth, fifth, and
six planets orbit in the star's habitable zone so they are particularly likely to have liquid water on their surface. This

For thousands of years, Astronomers and scientists have been constantly exploring space for extraterrestrial life. Despite a lot of research, we have not
yet been able to find any evidence of life. A common misbelief regarding extraterrestrial life search is– most of the people in the world believes our
major religions do not approve the theory of life beyond earth. According to the Bible, God has sent his most intellectual creation– humans to earth and
denies any possibility of intelligent life to exists anywhere except Earth. Also, many other well–known religious books like The Quran and the Torah
never discussed the fact that life beyond earth might exist. Here on the Earth, we have an abundance of water which is an essential thing

Thus, humanity was able to rise in to the monopolizing civilization it is today. Most of the hospitable worlds NASA has identified, unfortunately,

scrupulously screening the sky, the civilization will likely be long dead. As geologists lugubriously prophesy, humanity will also eventually collapse by
geological and climate change if it does not destroy itself. Whether long deceased or incubating in the midst of their infancy, extraterrestrial intelligence
may likely never encounter human civilization simply because of the distance and time that separate earth from the social hum of the

Others single celled organisms, and still others might support multicellular organisms, including those advanced enough to develop the technologies to
