Planet: (a) Orbits a star‚ (b) large enough for its own gravity to make it round‚ (c) has cleared most other objects from its orbital path. Sun: The star of our solar system. Star: Large‚ glowing ball of ignited gas that generates heat and light through nuclear fusion in its core.

We chose this topic on Dark Matter as it intrigues us what is beyond our atmosphere and what is it made off. We want to know how Scientists realized

The main theme of "The Star" by Arthur C. Clarke deals with faith. Clarke defines faith as having belief and trust in God with strong conviction. Clarke believes that one must have faith not only during blissful times‚ such as during the time of creation‚ but also during time of anguish‚ such as when destruction occurs. God "created" when a star flew over Bethlehem‚ just as God destroyed a star‚ the Phoenix Nebula‚ and its surrounding planets including any life that may have lived there. God does

The movie was based on a novel by Michael Crichton. I chose this movie because I wanted to know about the perception of global health over forty years ago. Some of the contemporary diseases like SARS‚ Avian Flu‚ and swine flu that threaten global health today were either unheard of or

working at Mt. Wilson‚ Hubble proved that there were other galaxies existed‚ outside the Milky Way. By taking many photographs through the 100-inch reflecting Hooker telescope he devised a classification system for the various galaxies he observed. He divided galaxies into elliptical‚spiral‚barred spirals‚ and irregular galaxies.Not only that but‚ he sorted the galaxies by shape‚brightness‚ and distance; it was then he noticed redshifts in galaxies’ light emissions were moving away from each other at a

Edwin Hubble. Hubble made the observation that the universe is continuously expanding. He discovered that a galaxy’s velocity is proportional to its distance. Galaxies that are twice as far from us move twice as fast. Another consequence is that the universe is expanding in every direction. This observation means that it has taken every galaxy the same amount of time to

consists of billions of galaxies that each contain billions of stars. Around some stars Planets and moons trace elliptical orbits. Within these orbits there are spherical bodies. These range in size from large asteroids to tiny particles smaller than a grain of dust‚ all of this is classified as baryonic matter by Astronomers. The fundamental core of the universe is known as the atom. During the 1970’s astronomers collected information surrounding the mass of Galaxies. They calculated this by
