The Causes of the War of 1812 essays

The Causes of the War of 1812 essays The War of 1812 was not just a battle against an external foe but stemmed from internal problems as well. The external enemy that the United States was facing was Britain, but that was not the most severe dilemma that they faced. The real problem that was occurring during this time was the internal struggle going on in the United States of America. These internal conflicts consisted of matters such as the issue of the north part of the country which was federalist did not want to go into war, but the south part of the states, which were anti-federalist wanted to go into war. Another issue was the war hawks, a group of western and southern leaders that was firmly Republican in their party's loyalty and encouraged war; the war hawks would become a cause for more internal problems facing the United States during the period around the War of 1812. One issue that supports the statement that internal struggle was a factor that led to the War of 1812 is the issue of the dispute between the northern part of the United States; which, being mostly federalist, was loyal to the British, not wanting to go to war and the southern part of the United States, having enough of the British presence on U.S. soil, wanting to go to war. This dispute was over whether or not to go to war; anger and rage flew back and forth during the heated debates about facing Britain in a battle or just backing off. The north wanted to back off and did not want war, while the south craved to get Britain out of the U.S and teach them a lesson. This caused great conflict in Congress and the government as a whole. This conflict grew in size and was one of the major reasons that the U.S. decided to go to war with Britain, without the influence spurred by this conflict, war may have never occurred. The last issue that caused U.S. internal conflict was the presence of the war hawks, a group of southern and western leaders that encouraged war against Britain due to th...

How to Find the Lyra Constellation

How to Find the Lyra Constellation The nighttime skies of the northern hemisphere summer and southern hemisphere winter feature a tiny constellation called Lyra, the Harp. Located next to Cygnus the Swan, Lyra has a long history and harbors a few fascinating surprises for stargazers. Finding Lyra To locate Lyra, look for Cygnus. Its right next door. Lyra looks like a small lopsided box or a parallelogram in the sky. Its also not far from the constellation Hercules, a hero honored by the Greeks in their pantheon of myths and legends. The Myth of Lyra The name Lyra comes from the Greek myth of Orpheus, a musician. Lyra represents his lyre, made by the god Hermes. Orpheus lyre produced such beautiful music that it brought inanimate objects to life and charmed the legendary sirens. Orpheus married Eurydice, but she was killed by a snakebite, and Orpheus had to follow her to the underworld to get her back. Hades, the god of the underworld, said he could have her back as long as he didnt look at her as they left his realm. Unfortunately, Orpheus couldnt help but look, and Eurydice was lost forever. Orpheus spent the rest of his life in grief, playing his lyre. After he died, his lyre was placed in the sky as a tribute to his music and the loss of his wife. The constellation Lyra, one of the 48 constellations of antiquity, represents that lyre. The Stars of Lyra The IAU official constellation outline of Lyra. This also shows the location of two deep-sky objects observers can search out. IAU/Sky Telescope.   Constellation Lyra has only five main stars in its main figure, but the full constellation with all its boundaries contains many more. The brightest star is called Vega, or alphaLyrae. Its one of the three stars in the Summer Triangle, along with Deneb (in Cygnus) and Altair (in Aquila). Vega, the fifth-brightest star in the nighttime sky, is an A-type star that appears to have a ring of dust around it. At 450 million years old, Vega is considered a young star. It was once our North Pole star about 14,000 years ago and will be again about the year 13,727. The Summer Triangle and the constellations that lend their stars to it. Carolyn Collins Petersen Other interesting stars in Lyra include ÃŽ µ Lyrae, which is a double-double star, meaning that each of its two stars is a double star, as well. ÃŽ ² Lyrae (the second-brightest star in the constellation) is a binary star with two members that orbit so closely that occasionally material from one star spills over to other. That causes the stars to brighten as they do their orbital dance together.  Deep-sky Objects in Lyra Lyra has a few interesting deep-sky objects. The first is called M57, or the Ring Nebula. Its a planetary nebula, the remains of a sun-like star that died and expelled its material out to space to form what looks like a ring. Actually, the cloud of star-atmosphere material is more like a sphere, but from our point of view on Earth, it looks more like a ring. This object is easiest to spot with good binoculars or a telescope.   The Ring Nebula as seen by Hubble Space Telescope, with a white dwarf at the heart of the Ring Nebula. This is a Hubble Space Telescope image. Through binoculars or a small telescope, the ring looks like a small greyish-green oval. NASA/ESA/STScI. The other object in Lyra is the globular star cluster M56. It, too, can be seen with binoculars or telescope. For observers with a good telescope, Lyra also contains a galaxy called NGC 6745. Its more than 200 million light-years away, and scientists think it collided with another galaxy in the distant past.   Scientific Findings in Lyra The constellation Lyra is home to stars with planets that orbit them. Theres a Jupiter-mass planet circling an orange star called HD 177830.  Other stars nearby also have planets, including one called TrES-1b. It was discovered crossing the field of view between Earth and its parent star (called a transit discovery), and theres some thought the star might be somewhat like Earth. Astronomers will have to do more follow-up observations to determine what kind of planet it really is. Such planetary discoveries are part of the Kepler Telescopes mission to find stars with exoplanets. It stared at this region of the sky for years, searching for worlds among the stars of the constellations Lyra, Cygnus, and Draco.
