The Habitability of Planets in the Universe

Beginning of New Era May be the initial trip to Mars can be sponsored by any nation or some space agency. However, in the end Mars will be for everyone. There would be no boundaries on Mars like the one which has been set up currently in our Earth. Thus, Mars could be the establishment of a new period in human diplomacy. 5.

Technological advancements have made it conceivable for NASA to begin human missions to Mars by 2030 (“NASA’s Bolden”). The scientific community is working diligently on ways to reduce the cost of colonizing Mars, but undoubtedly it will cost billions of dollars to establish and maintain a permanent colony on the planet. Although opponents of space colonization believe it’s a waste of money to invest in Mars, Mars colonization has the potential to alleviate the overpopulated Earth's declining resources of water, fossil fuels, food and jobs. The demand on earth for its resources at this current level is one that will be impossible to maintain in the future. Global warming is clear evidence that the current global population and industrialization has put the sustainability of Earth in doubt.

Scientists believe that the earth’s gravity caught some of the debris and pulled it into the earth. Scientist Digregorio, Barry E (B4) stated that inside the debris of falling rock, were microorganisms. He notes that the microorganisms may have been the very start of life, as human civilization knows it. There is no way to prove his theory true, but it is a strong possibility. Similarities in planets led scientists to believe there is a common bond between Venus, Earth, and Mars.

Extraterrestrial life is life originating from elsewhere in the universe. Irrefutable scientific evidence of extraterrestrial life is yet to be found, but a lot of better evidence is found every now and then. Most scientists accept the idea of extraterrestrial life, stating that taking into account that our universe’s size, the number of galaxies, and most importantly the number of earth-like planets, are beyond our imagination. The above shows that if no life is found in our solar system, then that has no proof whatsoever that no extraterrestrial life exists. The universe is vast, way beyond our imagination.

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.

The search for extraterrestrial life is probably one of the most important quests of the century. Not finding life on the nearby planets doesn't prove anything about how common life is in the Universe. However, if we did find life (say on Mars or Titan), it would indicate that life was a very common phenomenon in the Universe. The discovery of extraterrestrial life would be the most dramatic scientific, social and religious event in history. Many of our values would change as we realise that we are not unique.

One problem trying to find a planet with life is that if a planet was the same as Earth, it would be almost impossible to find it because it would be super small. Scientists keep on trying and they know that sooner or later, scientists will discover a habitable planet. Exoplanets, also known as extrasolars, are very unique and they keep us curious. Scientists and astronomers know very little about exoplanets and there is a lot to be discovered. An example of this is if there are any other planets that support life or if earth is unique and the only planet that can be habitable.

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.

There have been numerous counts of scientific evidence that there is life on Mars. But also there has been scientific evidence that goes against this very ideal. The scientific evidence that support that there has been life and it is still there extinct today on this planet has stood the test of time even against other evidence that goes against this ideal. Mars is most likely planet that has the ingredients of life that is need for a living organism in the solar system other than the known planet Earth. These ingredients of life are the following.

The global structure of Mars is well documented through viewings by scientists. However, without actually stepping foot on the planet, all we know of it is through observation. Due to this, the issue of plate tectonics on Mars is a contested issue. While scientists are sure that the core of Mars is not active, which means no plate tectonics; they cannot be sure that there was never a time when there were. Mars was formed by materials that were released by the early solar nebula.
