Recommended: Essay on the life cycle of a star
Elements are often referred to as the building blocks of matter, combining to create not only life but everything surrounding it. However, these elements are not created on their own. They are forged deep within the cores of massive balls of gas dispersed throughout the universe and blasted through the vastness of space in their immense, self destructive explosions. Stars, through their violent birth to their even more violent death, manufacture the elements necessary for life. These giant balls of superheated gas begin their lives as nebulas, slowly evolving into the magnificent lights we see burning in the night sky and eventually dying by gravity, the same force that helped create them, scattering the plethora of elements they created across the universe, allowing life as we know it to occur. Stars are the source of human existence and life on Earth because through their life cycles, they create the basic elements necessary for life to occur and thrive.
Stars are born using the ingredients of hydrogen and gravity. Nebulae, clouds of stardust and gas, are “star nurseries where m...

Comparing the Stars of Bright Star and Choose Something Like a Star
946 Words | 2 PagesIn using this allusion, Frost not only continues the "poetic tradition" but adds all the depth of meaning of Keats' poem to his own. The star doesn't want much of us -- only to stay above us. He says that "when the mob is swayed" or when social, political, or moral upheaval takes place and the norm is to be radical, the star likes being above it all, condescendingly regarding the earth. When this happens, we should "choose something like a star" and concentrate on it.
Similarities Between Choose Something Like A Star And Bright Star

Black Holes
1549 Words | 4 PagesStars are born and reborn from an explosion of a previous star. The particles and helium are brought together the same way the last star was born. Throughout the life of a star, it manages to avoid collapsing. The gravitational pull from the core of the star has to equal the gravitational pull of the gasses, which form a type of orbit. When this equality is broken, the star can go into several different stages. Some stars that are at least thirty times larger than our sun can form black holes and other kinds of stars.
Informative Speech On Supernovas
1132 Words | 3 PagesHave you ever heard the phrase “We are stardust”? Chances are you have, but what exactly does that mean? As an Astronomy major and someone whose always been fascinated by the wonders of space, including the wonder of supernovas. I want to pass some of the information I have learned to you today by telling you the different types of supernova and what happens during a supernova.
What Astronomy Really Is
3723 Words | 8 PagesThe Sun is a huge, bright sphere that is mostly made up of gas that is about 5 billion years old. The Sun is the closest to the Earth, it is 145 million km distant (this distance is called an Astronomical Unit). The next closest star is 300,000 times further away. There are probably millions of similar stars in the Milky Way galaxy (and even more galaxies in the Universe), but the Sun is the most important to us because it supports life on Earth.
Orion Nebula

Cosmic Life and Death of a Star
1612 Words | 4 PagesIf 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.
Stellar Evolution
2295 Words | 5 PagesA 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...
Stars
641 Words | 2 PagesThe magnitude scale was invented by an ancient Greek astronomer named Hipparchus in about 150 BC He ranked the stars he could see in terms of their brightness, with 1 representing the brightest down to 6 representing the faintest. Modern astronomy has extended this system to stars brighter than Hipparchus' 1st magnitude stars and ones much, much fainter than 6.
Milky Way Research Paper
1417 Words | 3 PagesThe formation and evolution of the Milky Way galaxy come, on one side, from observations concerning chemical abundances in stars and gas and, on the other side, from the continuous improvement of stellar nucleosynthesis calculations (Chiappini et al, 2001). There are some important quantities relevant to the chemical evolution of the Milky Way, such as the star formation rate (SFR), the initial mass function (IMF), and gas is still poorly constrained. However, a good model of chemical evolution can allow us to impose constraints on such quantities (Chiappini et al, 2001). In particular, a good chemical evolution model should be able to reproduce observables larger in number than the number of adopted free parameters. Among the observables, there are in the center with the consequent formation of the bulge. During the second episode, a much slower infall of primordial gas gives rise to the disk with the gas accumulating faster in the inner than in the outer regions. (Chiappini et al, 2001). In this scenario, the formation of the halo and disk are almost completely dissociated although some halo gas falls into the disk. This mechanism for disk formation is known as “inside-out II scenario, and it is quite successful in reproducing the main features of the Milky Way (CMG97) as well as of external galaxies especially concerning abundance gradients” (Chiappini et al, 2001).
How Lasers Work
1129 Words | 3 PagesWhen first discovered, lasers were thought to be the ‘cure all’ for modern scientific problems. Although many limitations have been realized, lasers are slowly improving many different aspects of our lives. From eye surgery to industrial precision cutting and fabrication to medical marvels like tattoo removal, surgery, and even destroying isolated cancer cells, lasers continue to be a behind-the-scenes tool for improving our lives. Many people have heard of the lasers, but few know that the term is actually an acronym for Light Amplification by the Stimulated Emission of Radiation. Even still, fewer could explain how a laser works.
Star Formation
690 Words | 2 PagesThe sites of star formation in the galaxy are mostly located within molecular clouds – expansive, cool clouds of mostly hydrogen and helium gas. Molecular clouds are on average too diffuse to contract gravitationally, but within a cloud are regions of locally higher density, which are the sites of active star formation. It is not known exactly what causes molecular clouds and star-forming regions to be distributed as they are. However, it appears to be related to the spiral-arm structure of spiral galaxies, which is thought to be the result of density waves passing through the disk, compressing matter and igniting star formation in their wake, leaving the trails of young, hot, blue stars in their wake that are the primary feature of spiral galaxies.
