Captial Punishment

Captial Punishment The justification of capital punishment has been an on going debate for quite sometime. As in the case of any argument theirs two sides too each argument. In this particular argument "society's self defense" essay by Amber Young the opposed battle the idea of capital punishment and think that overall its unjust and falls under cruel and unusual punishment.Amber Young's evaluations on the issue of capital punishment reaches out to everyone and leave a trembling thought in ones mind. The thought or picture left is the number of helpless innocent victims that were brutally killed by Ted Bundy. This picture alone lets one feel no pity or remorse for Ted bundy. This essay clearly refutes the opposed arguments and brings in evidence to support her reasoning. The majority of her arguments are strong though in some of her reason's there could be a stronger persuasive voice in convincing the readers one way or the other.An ad from the Ecologist Green Party in Mexico pro...In examining the dea th penalty, this particular argument is trying to justify the death penalty through the case of Ted Bundy; Young uses good evidence and support giving a particular example of what happened when the death penalty was not in order. Young claims that Bundy had escaped twice from prison. From Bundys escape he was able to rape and murder six innocent victims, not including the previous thirty-two victims. If Bundy was only sentenced to death at least six people's lives could have been saved.(32-33) Young then furthers her reasoning showing the loop holes in the judicial system explaining that if he is not sentenced to death he still has the possible means of either escaping again, or even the possibilities of parole. This appeals to the safety of our people and questions are true safety even if Bundy is behind...

Star Clusters

Star Clusters Star clusters are just what the name says they are: groupings of stars that can include anywhere from a few dozen to hundreds of thousands or even millions of stars! There are two general types of clusters: open and globular.   Open Clusters The open clusters, such as the Beehive in the constellation of Cancer and the Pleiades that grace the sky in Taurus, are groups born in the same area of space but are only  loosely  gravitationally bound together. Eventually, as they travel through the galaxy, these stars  wander apart from each other. Open clusters usually have up to  a thousand or so members, and their  stars are  not more than 10 billion years old. These clusters  are much more likely to be found in the disks of spiral and in irregular galaxies, which contain more star-forming material than older, more evolved elliptical galaxies. The Sun was born in an open cluster that formed about 4.5 billion years ago. As it moved through our rotating galaxy, it left its siblings behind long ago. Globular Clusters Globular clusters are the mega-clusters of the cosmos. They orbit the central core of our galaxy, and their thousands and thousands of  stars are held together by a strong mutual gravity  that creates a sphere or globe of stars. Generally speaking, stars in globulars are among the oldest  in the universe, and they formed early in a galaxy’s history. For example, there are stars in globulars orbiting our galaxys core that were born when the universe (and our galaxy) was quite young.   Why Are Clusters Important to Study? Most stars are born in these big batches within large stellar nurseries.Observing and measuring stars in clusters gives astronomers great insight into the environments in which they formed. Stars born recently often are more metal-rich than those that formed much earlier in history.  Metal-rich means that they contain more elements heavier than hydrogen and helium, such as carbon and oxygen.  If their birth clouds were rich in certain kinds of elements, then those stars will contain higher amounts of those materials. If the cloud was metal-poor (that is, if had a lot of hydrogen and helium, but very few other elements), then the stars it formed will be metal-poor. Stars in some globular clusters in the Milky Way are quite metal-poor, which indicates they formed when the universe was very young and there hadnt been time to form enough of the heavier elements.   When you look at a star cluster, youre seeing the the basic building blocks of galaxies. Open clusters provide the stellar population of a galaxys disk while the globulars hark back to a time when their galaxies were forming through collisions and interactions. Both stellar populations are clues to the ongoing evolution of their galaxies and of the universe. For stargazers, clusters can be fantastic observation targets. A few well-known open clusters are naked-eye objects.  The Hyades is another choice target, also in Taurus. Other targets include the Double Cluster (an pair of open clusters in Perseus), the Southern Pleiades (near Crux in the Southern Hemisphere), the globular cluster 47 Tucanae (a  fabulous sight in Southern Hemisphere constellation Tucana), and the globular cluster M13 in Hercules (easy to spot with binoculars or a small telescope).
