Some scientists believe there was life on Mars due to a number of factors. For one we know there was at one point a substantial amount of liquid water when the planet was much younger. We also know Mars’s electromagnetic field has dampened, making it more susceptible to interstellar heat and radiation, thus eliminating the life that could have existed. There are also other several factors including volcanic activity and evidence of salt oceans.…
There is most certainly microbial life on other planets. Life cannot be produced by non-life. When the earth was created, it is incredibly likely that an asteroid, meteor, or cosmic dust had come to the Earth’s surface and began to grow, multiply, and evolve. There is evidence of extraterrestrial microfossils dating back millions to billions of years ago; indicating that, at one point, there was microbial life on other planets. Prokaryotes multiply by a means of asexual reproduction called binary fission. In binary fission, the cell simply needs to grow twice its size, and then it divides into two identical cells. Since prokaryotes are very simple organisms, and there is evidence of ancient extraterrestrial microbial…
In this day and age, we all wonder if we are the only species in this universe. Some believe we are not alone; others believe we are. There have been people who believe they have video proof that of extra extraterrestrial life forms. However, there has not been any undeniable proof of this until now.…
The article The Martian Chroniclers a new era of planetary exploration by Burkhard Bilger discusses Earth and Mars known as the “Goldilocks Planets,” this is because Earth and Mars both have the perfect environment for life to be sustained. I was first observed that Mars had evidence that it could sustain life in 1877, by the astronomer Giovanni Schiaparelli. Schiaparelli drew a map of mars as an “earthly paradise.” This was because he observed that the planet had what appeared to be continents and water channels on the surface. Although, it was discovered that Mars has less water contents then earth’s driest desert. Nevertheless, because of Mar’s atmosphere and geological environment Mars has the possibly that it can sustain life. NASA has sent many space crafts to explore what is on Mars the first was the Mariner 9 then, Viking 1 and Viking 2, the…
Have you ever wondered if we were the only form of life in the whole universe? I have and I think that out of all the universe and all the galaxies we haven’t explored yet, there has to be a different form of life besides us out there it pretty near impossible for there not to be.…
Are Aliens Real? Is there life on other planets? This is a question many people have considered at least once in their lifetime. According to Neil deGrasse Tyson author of “The Search for Life in the Universe,” all known cultures across all of the time have attempted to answer the question “are we alone?” According to Tyson, although Earth is the only known life in the universe there are many arguments that have been made that suggest that we are not alone (1) .…
People for years have been wondering and asking themselves if there really is some sort of life form anywhere else in the universe. I mean, the universe is huge so why not? Knowing that the NASA Curiosity Rover has found evidence that there once was a stream flowing vigorously across the surface of Mars. People can now see that there actually is a good chance that there is or has been life other than on the earth. If the scientist are…
For long time, the only place which life emerges in the universe was Earth, and the fraction of life bearing planets on which intelligent life appears in Milky Way was (according to the given value) . So it was difficult to define that there is intelligent life outside of the Earth. However, in our calculation, we plugged the number 2 in instead of 1, and this makes a very significant change because it indicates intelligent life emerges outside of Earth. Thus, the importance of the fraction 2 is that it proves the emergence of the intelligent life outside of Earth, and it dramatically increases the possibility of the existence of intelligent life in other planets.…
NASA does a “lot of different things” including looking for extraterrestrial life (NASA budget cuts, 2013). NASA has been on a mad hunt to try and find new life. A big accomplishment for NASA is that they have been able to find old microorganisms on Mars. This suggests that there has once been life on Mars. They are trying their hardest to try and get people living Mars. They have set up a program that allows people to sign up to live on Mars.…
(Abstract) This was a film about if there were life form such as aliens, somewhere else in our world that are living organisms just like we have here on earth and if so where could they be found. What things should we search for out into the stars to find other sign of life, this film goes into detail and try to answer all of these important questions.…
You must have heard of bigfoot, the notchless monster, and especially aliens! The question whether or not there is life on Mars sparks up many arguments. So far there isn’t much evidence to proof whether life exists on Mars. Mars doesn’t have enough resources to keep an organism alive, which explains why nothing is interacting with its atmosphere. “Everything learned from space exploration thus far indicates that the knowledge lying in wait for those who manage to observe the universe from outside Earth's atmosphere will be far grander than anything uncovered to date.”. Although the evidence from Mars’ exploration indicates that life doesn’t exist there; the further exploration of space is necessary to help us humans on Earth to expand our…
Just like earth things change on those planets so if scientists telescopes do not detect life right now that does not mean there was no life ever on some of these planets. If one day we were able to visit these planets we would be able to detect certain physical and chemical evidence of life before. Even a planet that has no life today may hold evidence of ancient life forms from past generation. For example, archaeologists can detect that dinosaurs were alive along time ago even though they are long gone by finding physical evidence like fossils or chemical evidence from them. Another reason why Astrobiologists (Scientists that study the life) do not know right away about a planet, is they look at its current conditions, and for signs that it could have been habitable in the past. Water leaves behind evidence of possible life. Mars, for example, has what looks like dry river and lake beds, making astrobiologists wonder if the planet could have once been with life that is why many people talk about Mars. If Mars was, there may be enough remaining liquid water to sustain microbial life deep underground or under the frozen ice caps (The University of…
There have been numerous accounts of UFO (Unidentified Flying Objects) sightings in the night sky. There have been crop circles, in fields that are unexplained. The ancient civilizations, like the Aztecs, Mayans, Incas, Egyptians, Celtics, and Greeks provide evidence which points toward extraterrestrial life. The very idea of intelligent life existing besides our own and that life being extremely intelligent, almost God-like, can be a very terrifying. The evidence that follows will clearly state that we are not alone in the universe.…
Are we alone? That is the question many scientists and civilians have pondered since the beginning of civilization. Beginning in 1959 on a small scale, scientists have worked day and night to answer that very question through experimentation and research. In the years since, the search for extraterrestrials has fallen under various names and has been taken control of by several organizations and people. In 1982, Carl Sagan, an American astronomer, cosmologist, astrophysicist, astrobiologist, and author wrote a letter directed to the Science community suggesting the idea of searching for evidence of other life forms amongst us in the universe. This letter was signed not only by Carl Sagan, but also by seventy-two other scientists who agreed…
scientists consider extraterrestrial life to be plausible, but, till this day, there is no direct evidence…
