Earth Like Solar Planets
Throughout the course of human history, astronomers have wondered about the possibility of finding life beyond the solar system. In the last 20 years, there has been more of an emphasis on identifying other earth like celestial bodies that are orbiting distance stars. This has been taking place through the launch of various orbital telescopes such as: Kepler. Monitoring over 150 thousand stars, Kepler is identifying earth like planets that have similar kinds of signatures. What makes Kepler so unique is that it can use select criteria to determine which planets are in line with these objectives. While at the same time, it is segregating those bodies that are considered to be false positives. This is illustrating how science has evolved to the point that 8 different earth types of planets have been discovered in other galaxies. To fully understand what is taking place requires examining the different discoveries. This will be accomplished through looking at: the surface temperature, planetary mass, star type, its distance from Earth and known masses of companion planets. Together, these different elements will provide the greatest insights as to the significance of these discoveries. (Seager 1 -- 15)
Gliese-58d
Gliese-58d has a surface temperature of between 0 and 40 degree Celsius. The planetary mass is about five times as large as the earth. The star type is the known for being M. class body (Galiese-581). This is about 100 billion years old. It has a red dwarf sun and is located inside the Libra constellation. The distance of the plant to Earth is 122 trillion miles. Its distance from its sun is approximately 322 million miles. The orbit of the planet is considered to be circular in motion (with the celestial body completing an orbit of the sun every 37 days). The other companion planets in this solar system include: Gliese-58c and Gliese-58g. It has similar earth...
As a result, it does belong on a list of earth like planets. This means that there is the possibility it can be able to sustain basic and intelligent life forms. (Lloyd 106 -- 115)
Gliese-58g
Gliese-58g has a temperature of between 0 and 40 degrees Celsius. The planetary mass is considered to be three times larger than Earth. The star type is the known for being M. class body (Galiese-581). This is about 100 billion years old. It has a red dwarf sun and is located inside the Libra constellation. The distance of the planet to the Earth is approximately 123 trillion miles. Its distance from the sun is about 350 million miles. The other companion planets in this solar system include: Gliese-58c and Gliese-58g. It has similar earth like temperatures that are able to sustain life and they contain water. These elements are showing how it does belong on a list of earth like planets. Therefore, there is realistic possibility that it can sustain basic and intelligent life. (Lloyd 106 -- 115)
HD-5512b
HD-5521b is the only planet that is orbiting the star known as HD-5512. The approximate temperature is about 47 degrees Celsius. The mass of the planet is .69 the size of Earth. The likely age of the star is about 25 billion years old and it located in solitary star. Its distance is approximately 250 million miles from the sun. As a result, this is only planet in this solar system that is known for having the conditions of being able to sustain life. The basic orbit is considered to be cylindrical in nature. This means that it qualifies as an earth like body that is capable of sustaining basic and intelligent life. ("A Habitable Planet")
CoRoT-7b
The temperature for CoRoT-7b is 1,800 to 2,600 degrees Celsius. The planetary mass is 1.7 times smaller than the Earth. The age of the…

Extra-Solar Planets The word planet means "wanderer" in Greek. It derives from the fact that planets within our solar system seem generally to wander eastward about the so-called fixed stars across the zodiac constellations (Kolb). There is no clear consensus precisely defining what constitutes a planet, as distinguished from brown dwarfs, which are the material remnants of burned out ancient stars whose masses where too small to form white dwarfs or
At the present energy set-up nuclear energy provides around 20% of world's electricity. This energy is produced naturally -- by the sun and other stars making heat and light- and artificially-electricity from nuclear power plants. The nuclear power plants produce more energy using less fuel compared to the fossil fuels and hence it is seen as an environmentally friendly energy source (Ansolabehere, et al., 2003). However, the true scope
The last major x-ray flare occurred in 2003 ("O'Dell). Most of the energy from an x-ray flare is absorbed by the earth's ionosphere ("O'Dell). Thus, a CME can be far more dangerous for human societies than an x-ray flare. The first and most subtle observable phenomenon signaling an upcoming solar storm are known as coronal loops, which are "kinks in the magnetic flux form" forced to the surface of the

Furthermore, he argues, a technological culture is not an inevitable feature of human evolution. If other cultures had achieved ascendancy, then science and technology would not have emerged as a reference point for measuring intelligence. SETI's requirement for an almost identical technology, although scientifically understandable, is based on an impoverished concept of intelligence. According to Munevar, the development of a scientific culture, with access to radio communication, is highly contingent,
Search for Extraterrestrial Life: The Existence of Non-Human Intelligent Beings in Our Galaxy The possibility of extraterrestrial life has always intrigued philosophers, scientists, theologians and even lay people for centuries. The fascinating question of whether there are other intelligent creatures in space, however, remains unsolved despite technological advancements in science particularly because thus far, there still lacks conclusive evidence. Motivations for the search for non-human life range from scientific and philosophical
