Life on Other Planets
Life on Other Planets
Life on other planets, Is there another titan planet out there that harbors life? Scientist have found two such planets in a neighboring but distant Solar System. Which planets are habitable and is there already life there or basically in general, “Is there life in outer space?” That is the question and debate among astrologists and scientist alike about this discovery of two planets that orbit the red dwarf star of Gliese 581 (Gliese 581c.eu).
The fascination of intelligent life other than us has led to many studies and theories. With recent discoveries about the universe and the finding of Gliese 581, the idea of intelligent life has become even more intriguing. The implications of proving life exists on other planets and communicating with them could have an enormous impact to our society. The following discusses the possibilities of life on other planets by studying what sustains life on planet Earth, possible life within our Solar System, the discovery and study of other life bearing planets, examines what criteria may sustain life in other stars systems, and current programs studying extraterrestrial life (Koch and Borucki, 1996).
Recent technological advancements have confirmed the existence of relatively large planets around other stars. Earth-like planets orbiting other stars have yet to be discovered, but most astronomers believe one will be found. In order for a star to maintain a potentially life-giving planet within its orbit certain criteria would have to be established and maintained. Stars have been classified by The Harvard one-dimensional temperature classification scheme (based on hydrogen Ballmer line strengths) was developed in Harvard College Observatory in 1912 by Annie Jump Cannon and Edward C. Pickering (Koch and Borucki, 1996). This classification is ordered from hottest to coldest, comparing mass, radius and luminosity to our Sun. Stars are catalogued by the letters O, B, A, F, G, K, and M. These

    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.…

    Red supergiant stars have the ability to possibly support life. If you are at least 7-22 au it can be a good habitable zone for life.One reason why scientist believe it can support life is that it is mostly like our sun.Most of the red supergiant stars hardly rotate either they rotate very slow or sometimes don't even rotate.Hydrogen is what mostly runs the stars because without it there will be noe fuel to burn in the center and that's when the stars die or blow up like the supernova.…

    When a bunch of Exoplanets orbiting the same star are discovered all at once the closest one to they star will get a 'b' and then the next one out 'c' and so on. Now you might be wondering, why do the planets start with the letter 'b'? That's because astronomers use a capital 'A' to indicate the star in a solar system or the brightest star if there is more than one.So in a binary system the brighter star will get a capital 'A', the dimmer star will bet a capital 'B' and the first planet would get a lowercase 'b'.…

    Therefore we can also infer that, our solar system is not the only place for life to exist, but other extraterrestrials may still habituate in other planets outside our solar system. Whether primitive or intellectual, discovery of such extraterrestrials would bring about significant breakthrough in science and technology. Although such extraterrestrials have never been determined or found, many people still believe in them. These believers have their own logic behind extraterrestrials existence. Institutions such as NASA and SETI are among the very few donation dependent organizations which conduct active projects in order to search or seek out other forms of life existing outside this planet. Using high resolution telescope…

    The Universe has been a continual mystery to humanity. Throughout human history, individuals have been searching for answers to numerous questions that were provoked by the unknown space above their heads. Discoveries made by shamans, priests, and scientists have increased curiosity about the esoterics of the Universe rather than bating it. Though it may seem as if we know a lot about the Universe nowadays, this is only an illusion. The most significant mystery still lies in the question, “Is there extraterrestrial life?” Just as Christopher Columbus saw that first glimpse of previously unknown land on the horizon, it may turn out that we will happen upon another species that is as intelligent as us.…

    Many famous scientists, such as Stephen Hawking, Albert Einstein, and Miyuki Hatoyama, believe in extraterrestrial life. Experts base their belief on statistics of huge numbers that extraterrestrial life has the high probability of existing. There are billions of galaxies that have millions of solar systems and trillions of planets. Many of these planets must have some type of life form due to the infinite probabilities. Recently, NASA discovered that Mars has ice on the surface which indicates water was present when the planet was warmer. The most important element to sustain life is water. If Mars had water, could it have had intelligent life forms in its history?…

    Humans have always been wildly fascinated about the possibility that extraterrestrial life could, does currently, or has existed elsewhere in the universe. This is a subject that has been questioned by humankind for at least 2000 years. Lucretius, a Roman poet from the first century B.C., had suggested that “just as life originated by spontaneous chemical interactions on Earth, ‘we must acknowledge that such combinations of other atoms happen elsewhere in the universe to make worlds such as this one…. there are other worlds in other parts of the universe, with races of different men and different animals (Hobson quoting Lucretius, 2006).’” It is thought by many anthropologists that the discovery of life elsewhere in the universe would completely change our world’s sense of self. We would no longer be alone; our understanding of existence would change exponentially.…

    One of the deepest fascinations of mankind has always been if our existence is a lone existence, or if there is life elsewhere. Since the beginning of life forms that were consciously aware of their actuality on this rock floating through space that we quaintly call home; mankind has always sought to explain our purpose, beginning, ending, and our connectivity to the universe around us. This is why each society throughout the centuries has invented their own unique deities to explain the wondrous happenings that occur to keep life prevailing here. That and the fact that we don’t like to feel as though we are alone in this massive universe. Before we could conceive the concept that life could exist elsewhere society leaned upon the comfort that we had an ultimate creator(s), but this unfortunately lead to the divine rights mindset creating the misconception that we were special and thus inhabited the sole planet to harbor life. Then as time progressed people created the abstract concept that there was intelligent life outside of our planet and that it was hostile, leading to fear of life beyond our planet. No matter what time period or religious background one may be from, they all have the same curiosity to know if we are in fact alone; or if we have some form of cosmic neighbor. In this…

    Denise Chow, Super Earth - 1 of 50 Newfound Alien Planets, Could Potentially Support Life (SPACE.com Staff Writer, September 12, 2011) published an article about the latest development of discovery of more than 50 new alien planets — including one so-called super-Earth that could potentially support life which discovered by an exoplanet-hunting telescope from the European Southern Observatory (ESO). Exoplanet or extrasolar planet that orbits a star other than earth's sun was observed from the High Accuracy Radial velocity Planet Searcher instrument, or HARPS. By studying the properties of all the alien planets detected by HARPS so far, Astronomers found that approximately 40 percent of stars similar to the sun is host to at least one planet that is less massive than the gas giant Saturn. In other words, approximately 40 percent of sunlike stars have at least one low-mass planet orbiting around it.…
