Extract of sample "[Astronomy subject] The Galaxy Zoo"

John Q. A Astronomy 13 Aug The Galaxyzoo My experience of online ial the “GalaxyZoo” was incredible. The website offers lots of information, pictures of the galaxies and queries along with the training program. It has easy registration process, which took just 2 minutes. You need to get registered as a galaxy classifier to take part in the process of training and research, for which, you fill in the login details that include the login ID, name, email and password fields. The members of the website get access to a range of images and information, which are very unique and educational. The website has marvellous pictures of different type of galaxies, and it provides information and questionnaire related to the behaviour of galaxies, their shape and color in the space.
The GalaxyZoo website provides many interesting facts about the galaxies and the Universe. The database of the website provides an insight into galaxies and its evolution. The database stores about 250,000 samples of galaxies and the members are given a set of questions which are based on pictures of these galaxies. The visitors can take part in the questionnaire, which is based on the images of the galaxies. The visitors to the website have to look at the image and answer the questions based on his/her interpretation of the image. Some of the questions which are being studied are
Is the galaxy simply smooth and rounded, with no sign of a disk?
Does the galaxy have a predominantly clumpy appearance?
How many clumps are there?
Is there one clump which is clearly brighter than the others?
Is the brightest clump central to the galaxy?
Does the galaxy appear symmetrical?
Do the clumps appear to be embedded within a larger object?
Is the odd feature a ring, or is the galaxy disturbed or irregular?
The various researches showed the nature of galaxies such as the information related to the shapes, colours. It was assumed the color of galaxy was red and its shape was elliptical. However, it has been interpreted from the images of GalaxyZoo that one-third of galaxies are red spirals and a larger number of elliptical galaxies are blue -- which are in the process of forming new stars.
Earlier it was assumed that galaxies spin in opposite directions but research on pictures found that the two galaxies which are nearby, spin in the same direction, instead of opposite directions. This can be used to interpret the spinning behavior of galaxies. The research on galaxy disks showed the galaxies have larger contraction (bulges) which are central to redder disk galaxies. The research on disk galaxies with smaller central concentration is also significant in this context.
In the process of explaining the behavior of galaxies, GalaxyZoo found numerous new things in space which were called Galaxy Zoo peas. Certain blue objects were noticed in some images, which were named Voorwerp by the members of GalaxyZoo.
GalaxyZoo is the website which was launched in July 2007. It was based on the data set generated from millions of galaxies using a robotic telescope - the Sloan Digital Sky Survey. There are numerous projects which are handled by GalaxyZoo and several professional telescopes are used to track the images of galaxies.

...?Studying the Sun The Universe is a vast embodiment of unknown knowledge in which our tiny planet is apart of the giant picture, which makes individual humans insignificant in the grand scheme. However, humans are natural inquirers when it comes to the unknown. Civilization has come up with technology, which allows us to examine far and diverse celestial objects. Sometimes, however, observation cannot merely occur at just the visible level. Scientists are interested in the composition of these objects, especially stars due to the fact that nuclear fusion allows them to create denser elements in the core, which can serve as an indicator for how old the star is. One of these methods is through the use of spectroscopy. Spectroscopy... the Sun...

...interesting opportunities for us to take part in the hunt for radio signals from exoplanets. 2. Galaxy Zoo Galaxy Zoo simply requires identification of galaxies by participants. The project was launched in 2007 and has changed over time. The team has changed data collection methods over time, however, for the participants the calculations are not necessary and the data is processed separately by the team. The project is very simple as it only involves identifying the shapes of the galaxies. Images are provided by Hubble Space Telescope and Sloan Digital Sky Survey. We need to systematically classify and help the team in identifying...

By Tim Appenzeller Photographs by Frans Lanting Modern landscapes offer glimpses of the way our planet may have looked billions of years ago. The early Earth was a vision of hell, all scalding rock and choking fumes. Since then, its surface has cooled, continents have drifted, mountains have risen and eroded, and life has emerged, benign and green. Nearly all traces of the planet as it was have been wiped away. But from clues in the oldest rocks, deepest magmas, and even the cratered face of the moon, scientists have traced the planet's... Earth DECEMBER...

... Geological activities of earth Earth is geologically and biologically active because of two energy sources; one internal and one external. The internal energy source is earth’s molten core while the external energy source is the sun. Earth is the only planet which is having both geological and biological activities. “However, considering the fact that the solar system began as a cloud of gas and dust that was near absolute zero we might wonder where the earths internal heat came from to drive the plate tectonics.” (The Heat History of Earth) It is a confusing question for the scientific world to find out the relation between earths internal activities with solar energy. If earth’s internal activities are related to solar energy... Geological ...

...Springtime of the Universe” asserts that a dead star creates the elements in a human body. Either philosophical theory of a trivial consequence of cosmic evolution or essential step in a grand cosmic scheme is incorporated into almost every culture and religion. From the Greek and Romans worshipping the Sun god to today’s intelligent design, worldwide culture and religion is based upon consequence or grand scheme. Since there are numerous examples, the agnostic individuals and the Intelligent Design movement in the American society today will be examined. Agnostic individuals do not believe a higher power created the universe. The Big Bang Theory is given as evidence that the Earth and surrounding galaxies were created...

History of Astronomy

... History of astronomy Astronomy refers to the study of objects far away from the world. Among the sciences, astronomyis the oldest of all having begun thousands of years in the past. The ancient cultures had believes which locked them from advancing in astronomy (Shu, H. Frank, 46 ). For instance, among the Egyptians who were polytheistic there astronomy did not become anybody’s concern. People just left the subject of the cosmos because they thought the universe was under the control of gods. The Jews were the only people worshipping one God and made a predictable universe. The coming of the bible, which was associated with the Jews, made a great impact in science. According to many, Greeks were the first people to know much... of their...

They are small icy objects orbiting the Sun. Meteoroids are smaller than asteroids made of metallic and stony objects. Conclusion The study of astronomy explains the properties of our solar system and the universe. The Milky Way is just a part of the group of galaxies called the Local Group. There are innumerable galaxies in our universe and scientists do believe that there has to be life at many places in our own and other galaxies but there are no ways to establish contacts with...

...The Cosmic Perspective Fundamentals Qualitatively describe the relationship between orbital period and distance from the Sun, and then quantitatively (use numbers, equations, or relationships as described in Chapter 3) explain it in terms of Keplers third law. Any planet takes a certain period to complete an orbit around the sun which is called orbital period. The distance between the sun and the planet and the orbital period are mathematically represented which is referred to as Kepler’s Third Law or Harmonic law. This is represented as P^2=ka^3 where p is the period, a is the semi-major axis and k is the proportionality constant (Bennett et al, 2009). This became an important law in astronomy as it helps determine the...

(2004).How well does the Rayleigh Sky Model describe the E-vector distribution of Skylight in clear and cloudy conditions. According to the Rayleigh sky model the daytime pattern of the sky is described in a polarized set up. The effect of Rayleigh scattering causes the light of the sky to have a definite pattern of polarization hence the blue color through the elastic scattering. This effect is mainly attributed to the scattering of light from water, aerosols, water and light from water molecules. At each wavelength the polarization is determined by the degree of polarization and orientation...
