In astronomy, Orion is the brightest one of the constellations. It stretches across the celestial equator—the projection of the Earth's equator into the sky—and can therefore be observed from almost any part of the world. At a 10:00-PM observation of the sky in the middle latitudes, Orion first appears in the east in October, reaches its greatest height in mid-January, and drops below the western horizon in late March. Moreover, Orion is among the most spectacular constellations, with many bright stars and scores of fascinating stellar objects. It can be quickly distinguished by four bright stars arranged in a sloppy rectangle around three stars set in a line—the famous “belt” of Orion.
Legends have described Orion's presence in the

Apollo, her brother, accused Orion of distracting Artemis from her duties. As a lesson, Apollo tricked Artemis into shooting Orion through the head with an arrow. When she discovered the trick, the grieving Artemis honored Orion in the sky. In other legends, Orion was punished for his arrogance. The Earth released a scorpion to sting him, and Orion jumped into the sea. Because of their enmity, the two were placed on opposite sides of the sky, which is why the constellation Scorpius appears in the east just as Orion sinks below the horizon in the …show more content…
The great Orion Nebula lies just in front of the Orion Molecular Cloud, a particularly active source of star birth. The Hubble Space Telescope has imaged many proto-planetary disks around the stars forming there. The Orion Nebula is visible to the unaided eye in the region just below Orion's belt, often referred to as Orion's sword. Binoculars or a small telescope can reveal the true splendor of the Orion Nebula. Brightly glowing clouds surround the Trapezium, a dense multiple star recently born within the nebula. The Trapezium forms the center of a star cluster that may include more than 300 young stars. Closer to the belt, there lies one of Orion's most famous features, the Horsehead Nebula. It is difficult to observe, however, without a high-power telescope, and unless specific viewing conditions are

yourself in Northern California. frozen shore of Tule Lake. Now regard what sort of shape. this constellation takes a look. It sits there like a jagged scar.
Ptoloemy first charted the constellation during the second century. According to christian mythology, draco the dragon was first known to have tempted Eve at the garden of Eden. The constellation draco the dragon takes an aera of one-thousand eighty three square degrees. Draco the dragon has five known stars that have planets around them. The brightest star in the constellation is Gamma Draconis, or Eitanin. The constellation was also called Tawarent in ancient Egypt. Draco the dragon contains some deep-sky objects. One is the cat's eye Nebula. The
According to the PewResearchCenter, about 70.6% of Americans are Christian. This shows that more than 50% of Americans believe in Jesus. Similarly, more than 50% of Americans believe that Lucifer, the fallen angel is the Devil. Kim Addonizio writes a poem, in which she speaks about Lucifer the devil. She writes in Lucifer’s persona in which he explains why he should take over God’s role. In the poem, “Lucifer at the Starlite” by Kim Addonizio, she proposes the idea that Lucifer the Devil is taking over God’s role through the use of controversial topics and symbols to relate to the reader. Also, she uses sarcasm to make the reader critically think. It is important to note that she uses these literary devices in her poem, because it grabs the
Clusters like NGC 6530 were formed from the same cloud, and as a result have roughly the same age. This makes them of particular interest to astronomers. Because clusters are all formed from the same material, have roughly the same age, and distance from earth, variations in their brightness is only due to their mass ("Open Star Clusters"). This makes them particularly useful for studying stellar evolution. This cluster was first observed by Hodierna in 1654, and later found independently by Flamsteed in 1680 when he discovered the cluster was located within the Lagoon Nebula. Like most open star clusters, NGC 6530 is relatively young; having been formed less than 6 million years ago ("Young Stars Paint Spectacular Stellar Landscape"). It is known to consist of more than a hundred known bright stars, the light of which show very little reddening as a result of interstellar matter from the nebula, this is likely because the cluster is located just in front of the
Perseus, the twenty-forth largest constellation, is depicted as a man holding a sword in one hand and the head of Medusa in the other. Ptolemy discovered the constellation during the second century. Measuring 28 degrees in length, it lies in the Northern Hemisphere and can be seen best in December around nine o’clock P.M. It can also be seen in the Southern Hemisphere during the summer from latitudes north of negative thirty-five degrees.

As Clarice Lispector was writing what would become her last literary creation, The Hour of the Star, little did she know that while her body was plagued with the devastations of cancer, her mental struggle for peace and grace in death would inspire her most renowned novel. Perhaps it is because of those circumstances, she created a novel with intuitive reflections on both life and death, as seen through the life of the main character, Macabea. The story is narrated by Rodrigo S.M., and although Rodrigo attempts to maintain a neutral stance, he is often conflicted by his own perceptions and feelings. At the book’s commencement Rodrigo spends quite some time explaining that while the story is mainly about a woman, having the book narrated by a female would weaken the richness of content. He explains that a woman is incapable of clearly emphasizing the harshness of reality; that she is too emotional and attempting to explain the life of a wretched girl would be hard because her emotions would not allow an unbiased depiction of the cruelties of life. Macabea is introduced in the novel as a poor girl who does what she must to survive in the slums of Rio de Janeiro. She is, Rodrigo remarks, nothing out of the ordinary. Physically there is nothing about Macabea which sets her apart from the other countless street rascals who live hand to mouth. He then provides readers with some of her early life history, including how she almost died at birth because of rickets, and how both her parents succumbed to typhoid fever when she was a toddler. Finally after their death Macabea was forced to move in with her aunt, who too eventually passed away, but not before procuring the child a job to support herself. In the course of the novel the popular culture, though vague and metaphorical at times, affects Macabea and the secondary characters personalities and actions.
My favorite constellation is Pegasus. Pegasus is a winged horse, and I love horses. Back in the Muggle world, I rode horses in competition, and I was watching at Hogwarts during the Goblet of Fire celebration in which the girls' academy was brought in a carriage pulled by several Pegasi. Pegasi are very influential in popular Muggle culture, in television shows such as "My Little Pony" which features Pegasi, unicorns, and normal horses. Winged horses are beautiful and pristine creatures, the ultimate show of perfection.
The constellation I have chosen for this essay is Scorpius because I am a Scorpius so I have a connection with this particular constellation. The constellation Scorpius itself lies between the constellations Libra and Sagittarius in the southern hemisphere near the center of the Milky Way. This constellation symbolizes a scorpion and has 18 main stars,the brightest of which is the star Antares. I have chosen this constellation because Scorpius is my zodiac and I have looked upon the Scorpius constellation and I have found it to be quite stunning.
Nebula away so that it can avoid certain things. In the short story, “The Star,” the priest stated,
Solar nebula is a rotating flattened disk of gas and dust in which the outer part of the disk became planets while the center bulge part became the sun. Its inner part is hot, which is heated by a young sun and due to the impact of the gas falling on the disk during its collapse. However, the outer part is cold and far below the freezing point of water. In the solar nebula, the process of condensation occurs after enough cooling of solar nebula and results in the formation into a disk. Condensation is a process of cooling the gas and its molecules stick together to form liquid or solid particles. Therefore, condensation is the change from gas to liquid. In this process, the gas must cool below a critical temperature. Accretion is the process in which the tiny condensed particles from the nebula begin to stick together to form bigger pieces. Solar nebular theory explains the formation of the solar system. In the solar nebula, tiny grains stuck together and created bigger grains that grew into clumps, possibly held together by electrical forces similar to those that make lint stick to your clothes. Subsequent collisions, if not too violent, allowed these smaller particles to grow into objects ranging in size from millimeters to kilometers. These larger objects are called planetesimals. As planetesimals moved within the disk and collide with one another, planets formed. Because astronomers have no direct way to observe how the Solar System formed, they rely heavily on computer simulations to study that remote time. Computer simulations try to solve Newton’s laws of motion for the complex mix of dust and gas that we believe made up the solar nebula. Merging of the planetesimals increased their mass and thus their gravitational attraction. That, in turn, helped them grow even more massive by drawing planetesimals into clumps or rings around the sun. The process of planets building undergoes consumption of most of the planetesimals. Some survived planetesimals form small moons, asteroids, and comets. The leftover Rocky planetesimals that remained between Jupiter and Mars were stirred by Jupiter’s gravitational force. Therefore, these Rocky planetesimals are unable to assemble into a planet. These planetesimals are known as asteroids. Formation of solar system is explained by solar nebular theory. A rotating flat disk with center bulge is the solar nebula. The outer part of the disk becomes planets and the center bulge becomes the sun.
The starry night sky is a vast and beautiful realm that appears every night. It has fascinated humanity since the dawn of time. Coupled with our wonderful gifts of creativity and imagination, the night sky was our ultimate canvas and perhaps the oldest storybook. The sky has provided a place for us to draw mythical creatures and commemorate epic heroes. Our first record of the constellations date to approximately 6000 years old and were written in cuneiform (Coder, 2012). These texts were found in the valley of the Euphrates River and are simple constellations of animals (Coder, 2012). The question is why? It could be that human brain often seeks patterns in randomness. That humanity will see images in the sky to help our brains deal with the unorganized nature of the universe. However, I feel that this sells humanity short. The constellations are much more than the brain grabbing patterns and creating something it recognizes. These groupings of stars and stellar objects now hold our history. We have been passing along the stories of the constellations for thousands of years. After all, the sky is the perfect medium. It can store pictures and help tell stories and lessons that have lasted throughout time. As a small girl I remember vividly the Legend of the Dipper. How the little girl, in search of water for her ill mother, was compassionate on her journey. For her compassion she was rewarded and a reminder of this compassion is fixed in the night's sky (Bennett & Hague, 1995). I never forgot the story, or its message. How could I? That diamond encrusted dipper appears in the sky each night! It is wonderful how the constellations reach across time, culture, and beliefs. The most recognizable constellations usually originate from...
A star begins as nothing more than a very light distribution of interstellar gases and dust particles over a distance of a few dozen lightyears. Although there is extremely low pressure existing between stars, this distribution of gas exists instead of a true vacuum. If the density of gas becomes larger than .1 particles per cubic centimeter, the interstellar gas grows unstable. Any small deviation in density, and because it is impossible to have a perfectly even distribution in these clouds this is something that will naturally occur, and the area begins to contract. This happens because between about .1 and 1 particles per cubic centimeter, pressure gains an inverse relationship with density. This causes internal pressure to decrease with increasing density, which because of the higher external pressure, causes the density to continue to increase. This causes the gas in the interstellar medium to spontaneously collect into denser clouds. The denser clouds will contain molecular hydrogen (H2) and interstellar dust particles including carbon compounds, silicates, and small impure ice crystals. Also, within these clouds, there are 2 types of zones. There are H I zones, which contain neutral hydrogen and often have a temperature around 100 Kelvin (K), and there are H II zones, which contain ionized hydrogen and have a temperature around 10,000 K. The ionized hydrogen absorbs ultraviolet light from it’s environment and retransmits it as visible and infrared light. These clouds, visible to the human eye, have been named nebulae. The density in these nebulae is usually about 10 atoms per cubic centimeter. In brighter nebulae, there exists densities of up to several thousand atoms per cubic centimete...
If the nebula is dense enough, certain regions of it will begin to gravitationally collapse after being disturbed. As it collapses the particles begin to move more rapidly, which on a molecular level is actually heat, and photons are emitted that drive off the remaining dust and gas. Once the cloud has collapsed enough to cause the core temperature to reach ten-million degrees Celsius, nuclear fusion starts in its core and this ball of gas and dust is now a star. It begins its life as a main sequence star and little does it know its entire life has already been predetermined.
One thing us as humans have never been able to fully understand is astronomy. Always having an unexplained mystery, astronomy also has served as a way to keep time and predict the future. The word “astronomy” is defined as the study of heavenly bodies, meaning anything in the sky such as stars, galaxies, comets, planets, nebulae, and so on. Many people, if not everyone, is amazed by the night sky on a clear, moonless night.
