Goldilocks Research Synthesis Essay

NASA has already discovered a planet resembling Earth and even though the conditions for life to exist are quite precise, with the existence Earth-like planets and the universe being larger than the human brain can comprehend, the odds keep growing higher for life to exist somewhere out there amid the yet-unknown celestial bodies.

Planet Earth is the third planet from the Sun and the fifth largest of the planets of the Solar System. Earth’s surface is 71 percent water and is the only astronomical planet currently known where life exists. Earth is our home planet. Scientist and astronomers have studied our planet for Centuries and they have discovered much about our planet. Scientist have gained so much more knowledge of our Solar System in the last half-century after the NASA launched the first spacecraft and travel beyond Earth’s atmosphere has opened up to those who wish to explore. In the following paragraphs, we will discuss Earth and the

These chemicals were possibly delivered by large comets and asteroids flying throughout the solar system billions of years ago. Organics, compounds that contain carbon, oxygen, nitrogen, and hydrogen, are very essential in the search of possible life on other planets. The second key ingredient includes a liquid. Like water on Earth, there needs to be a source of liquid that would allow the compounds to mix and interact. Danny Faulkner, Ph.D. says “as the universal solvent, water is absolutely essential for life, making up the majority of the mass of many organisms” (icr.org). Finally, the third key ingredient to finding life on other planets is an energy source. A source of energy, like the sun to Earth, powers these chemical reactions to make life

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

Humans have been searching for a habitable extraterrestrial planet before Galileo even assembled the first telescope. Since then, we have identified 1030 extraterrestrial planets, but only an esteemed handful of these copious supply of planets would even permit the hardiest of bacteria and single-celled organisms, let alone intelligent life. Kepler-452b is one of the most speculated planets yet discovered because it orbits within the Goldilocks Zone, or the perfect distance from its star so that surface temperatures of the planet remain stable for liquid water, and thus for life. Given that it is 60% larger than earth, takes 385 days to orbit its star, Kelper-452b exhibits almost every desirable characteristic of a habitable planet. However, it is a jaw-dropping 6 billion years old, or 1.5 billion older that our own sun.

Earth as we all know it's Associate in Nursing improbably complicated and fragile network of interconnected systems that have developed slowly over the last four.5 billion years more or less. From the ashes of the massive Bang, this planet emerged as a mass of energy and components. From that new born mass of energy and components evolved structured, dynamic systems of solids, liquids, and gasses. The evolution of this planet continued to unfold over billions of years in such a novel method that eventually conditions arose with the flexibility to foster life.

Exobiology is the science that is concerned with the search for life in outer space; it may be called as astrobiology as well. The search for life in outer space has consumed the imagination of the humankind for long time ago. Nowadays, humankind has made a progress and found major discoveries in the quest for life existence in the universe and outer space because of the advancement of the technology. However, in the past, exobiology was considered as a science without a subject, where the people and other scientists laughed at and ridiculed the famous scientist and biologist Joshua Lederberg when he originated the term exobiology. Some people argue that life exists elsewhere in the universe, however, others believe that life only exist on Earth. A new study reveals that our galaxy, the Milky Way, has 100 billion or so stars, where 17 billion of them are Earth-size alien planets, and probably many more. The huge size of the galaxy increases the probability of life existence in the outer space. Are we alone in the universe? This question has captured the imaginations of scientist, theologians, and astrobiologists. However, they don’t know the answer yet. Understanding the complete definition of life and how life originated, and determining the techniques used for searching for life existence in outer space and evidences found can help to answer the question of “Are we alone in the universe?”

Buddha has been considered as a democratic crusader against the inequalities of the caste system and the empty pretensions of the Brahmanical theology. He is regarded as having weakened the foundations of the prevalent religious and social structure by repudiating the revelatory character of the Vedas and by challenging the arrogant claims to dignity, importance and merit to Brahmin priests. The following lines clearly depict the rejection of ascriptive superiority based on the physical fact of birth in a particular gotra and family

Among the billions of stars in each galaxy, many have planets that revolve around them. At least a few are bound to be of the right size and have the correct spatial orientation with respect to their star to allow life to grow. We believe this because life exists on the Earth. Astronomers have concluded that there must be hundreds of billions of other stars with conditions approximating those of the sun. Therefore there could be a million earth like planets with advanced civilizations in the Milky Way galaxy alone (Stilley). It is very probable that there is intelligent life elsewhere in the universe.

Since the very beginning of exoplanet discovery, astronomers have been seeking to find an earth-like habitable planet. This search especially rose in importance in the 21st century when we were faced with intensifying problems of resource scarcity and environmental deterioration which directly influence our being on earth. In order to investigate regions in the Milky Way to discover Earth-sized exoplanets in and approximate to a habitable zone, NASA sent Kepler, a Discovery-class mission spacecraft to identify planets in the Habitable Zone of main sequence stars and to generate a better estimate of how many stars in the Milky Way have such planets (Overbye,

All the habitable zone estimates assumes that these planets have an atmosphere. The exoplanet must accrete enough volatiles during formation to create an atmosphere and must be massive enough to sustain the atmosphere. The atmosphere also needs to be dense enough to stabilize surface temperature through climate feedback, such as the greenhouse effect. The atmosphere should absorb in the infrared spectrum but not in the visual

Furthermore, scientists have this big prediction in which they think that in about ten years they will prove themselves right. Technology develops more and more each day and in about ten years scientist might have advanced tools to travel through space and discover more. In some planets that scientists have discovered, they had found a gas giant. “A gas giant is a planet that is mainly composed of Helium and Hydrogen.” An example of a planet that has gas giants would be Jupiter, Saturn, Uranus, and Neptune. If a gas giant is found in a planet, the gas giant can give many characteristics to the planet. A planet that contains a gas giant could be big and cold, sometimes the characteristic of the planet gives scientist a big clue that there is no life in that planet. For example, if the weather is to cold in that planet or if there is

We now focus our attention on the formation of one particular planet, one that is so far unlike any other in the universe, Earth.

The earth is special mainly because it is located at the perfect distance from the sun. The temperature here is just right for water to exist as a liquid: get in as close Venus and the water just boils away as steam, while as far out as the orbit of Mars water is frozen to ice.

The argument suggesting life existing on other Earth-like planets has been present since man first looked into space and questioned his own existence and the existence of others like him. Today there are many theories on the existence of intelligent life elsewhere in the universe, but only one theory goes beyond them and into an even larger realm. The contents of this theory, known as the “multiverse” theory, suggest that humans on Earth live within one universe of many others that reside within a primordial vacuum containing many other universes (Jenkins and Perez). Each of these universes possesses potentially different natural constants and physical laws that govern them differently, thus calling forth some logical questions. First,
