Life on Other Planets. Essay

A question that has been asked for many reasons in the space world: Is there life on other planets? A mission called Curiosity launched in 2011. Curiosity has been on Mars since August.Curiosity’s goal was to find signs of water and see if Mars was suitable for life. The surprising fact on Mars is there is presence of water. One key element was Mars once had habitable conditions and there looks to be ice on the planet. Curiosity has been using a camera to take photos of Mars. It is much like the panoramic camera we have on Earth. Both cameras have the same material incorporated in them and are used for the same purpose.

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

Throughout history humanity has been fascinated by the existence of extraterrestrial life. Today such ventures are in the development process and the discovery of life beyond our solar system, no matter how primitive, may soon become a huge(important?) scientific breakthrough. The three basic things that are required to consider a place even remotely habitable are water, a source of energy, and organic materials. Habitability also depends on other factors that must also be taken into consideration such as how close the planet is to its star (in the case of our solar system, the sun), how long the water and organic materials existed there, and the size and mass of the planet. One must not confuse habitable with inhabited. The term

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.

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

James Green discusses in his speech the possibility of there being life beyond earth. Green starts off with a quote that is used in a lot of movies, books and television shows, “Is there life beyond earth in our solar system?” He follows this initial quote with one by Carl Sagan, an American astronomer, “It takes extraordinary evidence for extraordinary claims.” It is important for Green to use these two quotes as attention getters. He hooks the listener with his works and we begin to think if there really is life in our solar system then just on earth.

Extraterrestrial life has been a big topic for Americans since day one. According to author Lee Speigel there is an estimation of 48 percent of Americans throughout the nation that believe in life on other planets while only 35 percent reject the idea. Life on other planets exists. According to the article “Aliens among Us” by Paul, David extraterrestrial evidence has already been discovered such as different types of bacteria and even water. The article “Aliens among Us” is a credible source because it has many explanations and possibilities on how life on other planets can easily be real. Extraterrestrial life can be many things such as plants or living bacteria. Astronomers have proven that there is water in other planets such as Mars. Water contains different types of bacteria and cells, water in other planets can be one of our best piece of evidence that we can prove that there is life on other planets. There has been UFO’s crashes that have been recorded such as in Roswell, New Mexico 1947 but the government took all the evidence and it’s probably in Area 51. Although there is no hard evidence that proves aliens are real, NASA has announced that they will be able to find living creatures by the year 2025.

Speaker Credibility: When I took an astronomy course at USC, my class was getting into life on Mars. At the moment of my semester, NASA discovered water on Mars. This was a discovery that caught my attention therefore, decided to speak about it.

it was discovered that there are other planets like Earth out there that are able to accommodate life forms like our planet. And it is highly unlikely that we are the only living things out there in the big universe

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.

Spirit stumbled across rocks that pointed to an earlier, unrulier Mars that was marked by impacts, explosive volcanism and subsurface water [source: NASA Mars]. "Water is key because almost everywhere we find water on Earth we find life," NASA's Web site. However, we are still unsure life existed on Mars.

The thought that intelligent beings may exist somewhere in the universe other than the earth seems to fascinate certain people; therefore, for more than fifty-five years astronomers have listened for an indication of life from outer space. However, “E T” has been as silent as a tomb.

To begin with, there is more than one sun out there in space, and a sun can contain about one million planets in space. Scientists have discovered about one thousand planets orbiting distant stars. They have much more to discover! There is a big possibility that in one of those planets life could exist. Another big clue that scientist have discovered is that there are many galaxies in space and we live in one. The galaxy that Earth is located at is called the Milky Way Galaxy. A galaxy can contain many planets just like our galaxy can contains over billions of planets.

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.

possibility of life existing on other worlds has been the subject of speculation for years.14 In
