Extrasolar planet

Christopher Tran EAS 1601: Writing Assignment 1 13 October 2015 Why Giant-Planet Cores do not Spiral Towards their Parent Stars http://www.nature.com/nature/journal/v520/n7545/full/520040a.html Why are gas giant planets of exoplanetary systems at a distance of at least one astronomical unit from their host stars? As we learned in class, the gas giants form by accreting and colliding with smaller solid bodies from the disk. According to Duncan, this process of accretion can occur relatively fast…

observation in December 1612, Neptune was stationary in the sky because it had just turned retrograde that very day. This apparent backward motion is created when the orbit of the Earth takes it past an outer planet. Since Neptune was only beginning its yearly retrograde cycle, the motion of the planet was far too slight to be detected with Galileo's small telescope.[21] In July 2009 University of Melbourne physicist David Jamieson announced new evidence suggesting that Galileo was at least…

scientific revolution taking place around him during Renaissance-era Europe. At that time, scientists and astronomers like Kepler, Copernicus and Galileo had made astounding discoveries regarding the position and movement of celestial bodies such as planets and stars. Prior to this time, the Catholic Church held a large sway over the science of the time, and served as a “committee” that would decide what scientific theories would be published and what theories would be declared a heretic, or…

in the creation of millions of cosmic entities such as stars and galaxies. As incredible as the creation of these celestial beings are, there is something more exciting that it created; us. Along with these collections of stars and dust, comes the planet Earth and its ability to create and foster life. In the book Journey of the Universe, the authors, Brian Thomas Swimme and Mary Eveln Tucker, tell the story of the universe 's creation of life and its struggle to maintain perfect equilibrium…

named for the father of the Greek and Roman gods. Jupiter is very bright, wonder more quickly than Saturn but still not rapidly, name of the king of the gods. Mars wanders rapidly and erratically, (god of war) bright vary wildly, reddish hue, other planets are yellow and white. Venus wander but stays close to the sun, seen in the morning & evening sky, name of Greek and roman goddess of love and beauty. Mercury hangs over closing to the sun than Venus, bears the name of the swift messenger of…

Barbara Science Line. In other words, there are so many planets that, theoretically, it would be possible to count them but because to their number this task seems more like impassible. That is a big intrigue; presumably, in the universe can be uncountable number of planets similar to our planet in many ways, such as natural resources, pure water, appropriate temperature, and the others features. Otherwise, humanity has a marvelous blue planet, Earth, so why it is important and trillions of…

over again. Is it really possible to live on another planet? Few years later, I’ve did research through many space expeditions where NASA sent humans onto the moon. When the mission succeeded it was one of the greatest achievements of all time. That was when I came to believe that if we humans can set foot on the moon, and then we can accomplish many things in the world. During this year it is impossible for astronauts set foot on other planets because…

Tyson traveled around the country in order to ask people and research whether Pluto should be classified as a planet or not; this became problematic and controversial as people have different beliefs. In the film, a planet was defined as a “celestial body massive enough to clear its orbit” (“The Pluto Files”). According to the definition of a planet, Pluto cannot be classified as a planet because it interferes in Neptune’s orbit; again, this can be controversial among different people. I…

but also challenged the ancient belief in the uniform circular motions of the planets. Kepler’s new model is not only one of the greatest achievement in astronomy, but also advanced our understanding into modern physical concepts like gravity. In the sixteen hundreds, although more…

Feng Shui, which is believed to share valuable wisdom, common sense and sensitivity to nature. Feng Shui depend on astronomy to find correlations between humans and the universe. According to (Hurley, n.d). There are a lot of Chinese Dynasties that influenced Feng Shui, the Tang Dynasty, the Song Dynasty, and the Ming Dynasty. There are two types of Feng Shui, the Form School and the Compass School. Form School, the oldest school of Feng Shui, the Han Dynasty describes in it the “Book of the…
