...torical Analysis “Can Life Exist on Other Planets” Professor Danny Faulkner is the speaker in his article “Can Life Exist on Other Planets” and it summarizes the evolution of life on Earth and how we would need liquid water the gold standard to live and thrive on another planet. Faulkner’s purpose is to propose the idea of life on other planets by providing information of the evolution on Earth, searching for life on Mars, the need for liquid water, and the planets in our solar system's attributes. He acknowledges an informative tone to provide information of life existing on other planets for the audience. Faulkner begins to explain the broad definition of abiogenesis, the spontaneous appearance of life from a nonliving matter. He implies “if life did arise on Earth by itself, it would be inconceivable that this is the only planet upon which there is life”(Faulkner 7-8). He describes life on Earth as abiogenesis. If Earth were the only place that held life it would be a very “special” place; the definitive response from Faulkner suggests the evolution of life on Earth would support life on other planets. According to Lloyd Bitzer, exigence used for this article is that if life was found on other planets than ours. We would have a portion of people wanting to destroy...

...things that make up space from tiny specs of dust, to huge gigantic galaxies and solar systems. Solar systems is what makes up most of space, there are so many structures to the solar system. These structures consist of planets, gasses, and energy. THe one thing that holds all of this matter is a star in the middle of the solar system. These stars have a very large gravitational pull that holds everything in place, planets also have a gravitational pull but it's not as powerful as the sun's gravitational pull, which makes it so that the planets do not float away but also do not come crashing into the sun. Stars are immense balls of gas that produce...

...Evolution Through the Solar System Abstract Over the course the class has been about many different things through our solar system, land features, and more. This week we had to put together a paper describing how evolution has taken place through our solar system. The main objectives of the paper are to include the formation of the planets, the motion of the planets, the early revolution. Also, discussed is the scientists who discovered these properties of our solar system. For example Copernicus, Newton, Galileo, and Kepler. These scientists have all created or in some way helped to discover something new about our solar system. Evolution Through the Solar System Though scientists have been studying the solar systems for years. There are still discoveries made each year. Many of the discoveries have been interesting from the formation and motion of the planets, the early revolution of the planets, and the scientists who discovered what we know today. Formation Scientists have been studying the origin of our solar system for hundreds of years. Some findings are well supported while others are not as well received. The best news is we are not done concluding the formation of our solar system just yet. In 2006, the distant ice-covered body known as Pluto was reclassified as a dwarf and changed the model of our solar system from nine planets to eight. Today a planet is defined as, “A full-fledged planet is an object that orbits the sun and is large enough to have...

...searched for life in our solar system and outside of it for years. Speculation supporting and against the probability of life on other planets has been a subject of debate in the scientific word and beyond. The probability of life mathematically is extremely low even when all the elements of life are present. Stages of evolution and development needed to create life take time. This time that it takes to develop is difficult to come by in the Universe according to some scientist. To understand what it takes to produce life scientist look to life as it evolved on Earth for an example on how this occurs. Properties of Life on Earth Life refers to any living system that can maintain homeostasis, grow or have the capacity to do so, respond to environmental stimuli, reproduce in some manner, and adapt to environmental changes. Anything that can do these things is referred to as a living organism. Life on Earth consists of carbon forms. Carbon is a key component for all life that has naturally occurred on Earth. Molecules made of carbon bond with hydrogen, nitrogen, and mostly oxygen to make complex molecules. The substance carbon is in excess on Earth. It is easy for enzymes to move and manipulate carbon molecules due the size and the fact that they are lightweight. The most common elements found in living organisms on Earth are hydrogen, nitrogen, oxygen, phosphorous, sulfur, and carbon.

...Exoplanets are planets that orbit a star outside the solar system. The universe is about 13.8 billion years old and our solar system contains planets, galaxies and stars. With this information there is a possibility that there could be life on the planets that surround exoplanets. Exoplanets have become commonly discovered in the universe. In 1995 the first announcement of an exoplanet was made when a NASA Kepler Space Telescope was used by scientists to find an Earth-Sized planet orbiting a star 540 light years away. Based on the article, “Exoplanets 101” it says, “Since the first confirmation of an exoplanet orbiting a sun-like star in 1995, and with only a few, narrow slices of our Milky Way galaxy so far surveyed, we’ve already struck many rich veins. A recent statistical...

...The Planet of Aliens An alien is what we know to be something that is not native to planet earth, also known as an extraterrestrial life form. Although I do not believe that the green, one-eyed, Hollywood-influenced alien exists, I do believe that there are living organisms on other planets in this universe. The universe is so large that it is next to impossible to be able to examine every aspect of it, as we are still discovering new species here on earth. I do not believe that Aliens have not come to our planet; however, I do believe that there is life on other planets. As Joshua Kennon once wrote: Add in the possibility of multiple, or even infinite dimensions, which means entire civilizations could exist on a planet like Earth right alongside us without us knowing it, throw in the nature of time and time travel as it interacts with gravitational forces like black holes, and the concept exceeds the human mind’s ability to grasp. (Kennon) I agree with Kennon because if there are billions of stars in the universe, there has to be one relatively similar to that of the sun, and also a planet revolving around it the same distance away as earth is to the sun. Due to this assumption, there must be some planet somewhere with conditions similar to those of earth. I do not believe that in our solar system there is one however because the planets that are in our system are either too far or too close to the sun for life to be maintained. In another solar system there must be...

...there were still many planets the size of mars and mercury moving around the solar system closet to earth. The theory was that since the earth had formed most its layers that many of the iron minerals had made its way to the core of the earth and the outer layers were made of other types of less dense materials. In theory a planet the size of mars collided with earth in which it vaporized the earth’s atmosphere and outside crust, also vaporizing the crust of the other planet. This in return heated up the planets and caused large chunks of molten masses to shoot out into space. However due to the earths strong gravity pull not all of the molten chunks escaped out into space but however was trapped by earth’s gravity and stayed in place. Over thousands of years this molten mass would eventually turn into what we know today as the moon and to explain the low iron count of the moon. Another hypothesis is that of the Nebular hypothesis. It states that the solar system as a whole started off as nebula cloud of gasses and dust. Which in time a gravitational collapse happened and the cloud started to rotate? This rotation in returned caused the mass to start to heat up due the fact the gravitational energy transitioned into thermal energy. After time the mass starts to cool off leaving rocky material to condense into partials. Eventually these particles begin to slam into one another forming asteroid size bodies in return these bodies forming into the size of planets rotating around the...

...ABSTRACT: A solar tsunami is a rare astronomical phenomenon, caused by the magnetic explosion in the sun. The sun has spurted a huge cloud towards the earth which is full of electronic ions. The planet was hit by a “Solar Tsunami” racing 93 million miles across the space. Scientists have warned that the earth could be hit by a wave of violent space storm(Coronal Mass Ejection) after a massive explosion on the sun. This huge explosion could shut down the global communication and the satellites might get destroyed. “These eruptions occur when immense magnetic structures in the solar atmosphere lose their stability and can no longer be held down by the Sun’s huge gravitational pull. Just like a coiled spring suddenly being released, they erupt into space.” This means we have a very good chance of seeing major and prolonged effects, such as the northern lights at low latitudes.” The solar explosion that causes the tsunami has been observed by many satellites along with the Solar Dynamic Observatory, NASA. The blasts will reach to a maximum level in 2020 it is estimated. Along with this blast there was another blast of cold air circumference of the sun’s northern pole. A huge cloud has been thrown in to the space with these related developments. This paper focuses on the global changes caused by the future solar activity and also presented pre actions for safe guarding our lives.

...to the planet Earth. It is located in about 500 light-years from Earth and sails through its habitable zone, resulting to potentially watery surface. The planet was put outside the edge of the habitable zone from the fact that in only gets about one-third of the energy from its star compared to Earth. Though researchers find a potentially habitable planet we still need to surmount the problem of getting there or surviving the trip. (Anonymous, 2007) stated that we still don’t have the idea on how far the nearest habitable planet is, but the assumed distance from the Earth is more or less 20 light years. It is implied that a light year is defined as the distance light travels in a year which is 186,282 miles per second. When it is multiplied the result would be 5,874,589,152,000 miles. The article also stated that the fastest astronauts have ever travelled so far is 7 miles a second and it means that it would take more than 26 thousand years for us to travel the distance of a light year. (Fernando, 2015) discuss the 5 possible problems that we may encounter in living on other planet. (1) The concept of time will be utterly screwed. Earth has 24 hours in a day and 365 days in a year and it all depends on how fast the Earth rotate on its own axis and the length of its orbit. Technically speaking, every planet have different time depending on its axis and the length of its orbit. It is also stated there that measuring time is the most crucial elements in our daily life, and it...

...(Reuters) - An Anglo-German team of astronomers has discovered a new planet orbiting a nearby sun at just the right distance for an Earth-like climate that could support life. The team actually found three new planets orbiting the star 44 light years away, but only one of them is in the so-called Goldilocks Zone, the band around a sun where temperatures are neither too hot nor too cold for liquid water to exist. "The star HD 40307 is a perfectly quiet old dwarf star, so there is no reason why such a planet could not sustain an Earth-like climate," said Guillem Angla-Escude from Germany's University of Goettingen, who led the research with Mikko Tuomi at the University of Hertfordshire in Britain. The planet has a mass at least seven times that of Earth but it orbits at about the same distance from its sun, meaning it receives a similar amount of solar energy as Earth gets. More than 800 planets have been discovered outside our solar system since the first was detected in the early 1990s, but only a handful of those have been in the habitable zone. Even more rare are planets in the zone that rotate, as this one does, to create a day-time and night-time, which increases the chance of an Earth-like environment. Those that don't spin are said to be tidally locked, with one half in constant darkness. "This is the closest one to Earth in a habitable zone that is not tidally locked," University of Hertfordshire astronomer Hugh Jones told Reuters. "Just as Goldilocks...

...modern view of the universe 1) What is our Sun and what is its role in the solar system? a) Our sun is a hot ball of glowing gases that is at the heart of our solar system. b) Our suns role is to give out energy and heat. This energy and heat allows for there to be life on earth. However, even though our sun is unique and life giving there are billions of stars that are just like it in the Milky Way galaxy. (Solar System Exploration, 2012) 2) What is our Milky Way galaxy and the sun’s position in it? a) The Milky Way galaxy is a spiral galaxy that has arms that extend out from the center like a pinwheel. Our galaxy is one of about 100 billion visible universes. (Solar System Exploration, 2012) b) The sun’s posistion in the galaxy is in the Orions arm of the Mily Way. However, because of how our planets are set up in our system there is life on Earth. The Sun has an almost circular orbit. The sun is just the right distance from the center of our galaxy to promote life. The planets and our sun are just the right distance apart for one of our planets, Earth, to have higher intelegance life on it. 3) What is the Big Bang and what does it say about the age of the universe? a) Scientist says that the Big Bang is what created our universe. Edwin Hubble was the first, in 1929, to discover that the Universe was expanding an great speeds. Now Hubble discovered that planets and galaxies that were outside our own are moving away from use and that their speeds were proportional to...
