The Drake Equation: The Search For Extraterrestrial Life

The universe is huge and if it's that big it can hold many things including aliens. Many people report being abducted or seeing UFO’s. People have reported, have physical, or have heard aliens to prove they are real.

With all our knowledge of everything around us, overwhelming as it may be, there are still a lot of aspects that are unknown to even the smartest scientists. Did you know that humans know only 5% of the entire universe? Yes, everything we know about the Earth, the Milky Way, and all the planets is barely even a fourth of what comprises the entirety of the universe. Knowing that, it would be illogical to say that the creatures on Earth are the only forms of life in the universe. Today I will tell you about unidentified object sightings, close

Does life exist on other planets besides Earth? Has extraterrestrial life visited Earth recently or in our distant past? The notion of extraterrestrial life is a very intriguing subject possibly for as long as mankind has looked into the vast heavens gazing at the stars. Can one say that life on Earth was done by Mother Nature which some call evolution? Is life on Earth the result of creation or alteration by a higher power or being? Some people do believe that other forms of life except those on Earth do exist. Others consider it false because there is no absolute proof beyond doubts. There have been countless occurrences by individuals around the world of either being contacted or abducted by alien life forms. Many unofficial accounts describe the Earth as being visited by one or more alien species. These various alien species that possibly visited Earth may be interested in observing the development of the human species.

We live in a universe that is about 46 billion light years old. In a world, as massive as ours there must be some form of extraterrestrial life out in the galaxy. For thousands of years ancient peoples, such as the Greeks, have wondered the same question. Are we alone? As our technology advances, things such as videos and photographs are surfacing of people claiming to see such alien life. Whether it is an unidentified flying object, or if it’s from someone claiming to see an actual alien, there are thousands of people that believe they have seen proof. Some also claim that the government is hiding things behind our backs, like the Roswell UFO incident for example. Though many people refuse to believe in the existence of alien life forms until they see evidence, the fact that multitudes of people have eye-witness accounts, the improbability that we are alone, and the idea that we have thought of aliens so long, bring forth the evidence that proves something is out there.

Mars’ conditions make it extremely difficult for any type of living organism to survive. The text states “7) Environmental reaction. All animals interact with their environment.” (Source A). Furthermore, the ext in Source B states “‘We don’t find nitrates in the Martian soil,’ said Catling. ‘All life on earth uses Nitrogen. In proteins, [Nitrogen] is a structural element that holds life together. Life takes Nitrogen directly out of the air and puts it into the soil to form nitrates. But we don’t see nitrates on Mars.” This shows that if any type of organism known to us would not be able to survive on Mars. All life must rely on their environment, and they must rely on nitrogen as well. However, there is no nitrogen in the Martian soil, so the animals would quickly die off. Furthermore, Source B also states that there is too much carbon monoxide in the air for animals to survive. This is harmful to animals, and they could not survive in such conditions on

Are we alone? Are there people around us? Has anyone heard about aliens? Are they real? Can you answer all of those questions, if not, then just keep reading. In my opinion aliens do exist and there are plenty of evidence to prove they exist.

Aliens and life beyond earth has been a mystery for a long time. Many people and scientist have been looking for life outside of Earth, or just floating in the sky trying to get video of it. For all of human history we have been looking for extraterrestrial life, and these are the major events of finding, debunking, and moving forward to life on earth

I believe that Aliens are real and have been to Earth. I may not have seen a UFO before but if you really think about it the universe is so big you think we are alone in this universe? Even if its plant life or some other type of other living thing. Many people don’t really like to talk about alien sightings because people who don’t believe in it call them crazy.

The discovery of the Neptune planet was the result of various hypotheses, generated by different astronomers and mathematicians from 1781 to 1847. The article entitled “Accounting for Anomaly: The Discovery of Neptune” describes how Neptune was mathematically identified, before being directly observed, using the calculations of Urbain Le Verrier. He made the hypothesis that the Newtonian gravitation law could not fully explain the series of irregularities in the path of the Uranus planet. Le Verrier suggested the existence of another planet, after Uranus, that could affect its gravity. In 1845 his hypothesis followed a series of calculations to determine the nature and position of this unknown planet. By this calculations Le Verrier’s understood

The impossible was reached on July 20th 1969 when we sent the first man on the moon. The Apollo missions are the largest and most well known explorations that NASA has conducted. Ever since we reached this new high, our curiosity of space has grown even bigger. Funding NASA’s space program even further will continue to help us amplify our available resources and discover new information to benefit humanity. Not only that, but it could provide many ways for us to find a new home and expand our species farther into our solar system, potentially saving future generations. The expansion of this space program would be able to answer more of our questions than from what we can find here on Earth. Although there

According to Wikipedia, extraterrestrial life as a term is originated from the Latin words extra that means beyond or not of and terrestris that means something of or belonging to Earth and it is defined as life that does not originate from Earth. It is often also referred to as alien life, or simply aliens. This hypothetical form of life is said to vary from simple bacteria-like organisms to beings far more complex than humans. That kind of alien life has been hypothesized to exist in the Solar System and throughout the universe and this hypothesis can be based on the vast size of the universe. According to this argument made by scientists, it would be inconceivable and egoistical to believe

Preview Statement: The possibility of life on mars is an extravagant topic to look at. Before that, we must analyze Mars itself along with its conditions. First, we will talk about the ice caps located on Mars. Second, we will examine the water streaks on Mars. Third we will observe if the red planet is inhabitable for humans to conquer it.

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 we should be

Mars has water but it is frozen in the planet ice caps and under the soil. The atmosphere on mars is weak due the very high strong winds that occur. The surface temperature of the planet is freezing and the water on the surface of planet evaporates other than the ice caps due to the low atmospheric pressure of the weak atmosphere. According to brightkite.com, “Even with the bad temperature, weak atmosphere and said frozen water there still prove that there is life on Mars because there evidence saying that Mars’s living organisms could be sub surface ("'Strongest evidence yet to there being life on Mars'"). This means that the living organisms do have a chance to live and since there is water, wind, and cold temperature, this allows living organisms to breathe and exist inside the interior of the

Personally, the idea of either being alone in our galaxy or not alone in our galaxy gives me the chills. Our place in the Universe is undefined because of our lack of knowledge and insight. As of now, life on Earth is the only known intelligent life, but there are hypotheses and theories that suggest otherwise. I believe that the probability of life in our galaxy is high and that we have a high probability of finding it.
