Our Solar System INT1 TASK 1 The Evolution of our Solar System • Observations of the stars, sun, and planets appearing to revolve around the Earth, which seem to be at motionless, lead ancient astronomers to believe the Earth was the center of the solar system. • Claudis Ptolemy’s version of the Geocentric Model was the most widely accepted and recognized example of the Geocentric Model. • Nicolaus Copernicus published a book on his theory of a heliocentric system, the book, De revolutionibus orbium coelstium, puts the Sun at the center of the Solar System with planets revolving around it. It also pointed out that the Earth was in motion and that motion could explain the Retrograde motion of the planets.…

The stars are the majority and most widely acknowledged astronomical components that symbolize the most essential development of the galaxies. The disbursement, age, and the framework of the night sky in the galaxy maintain a record of the heritage, evolution and characteristics of our galaxy. More important the stars are integral to the fabrication and allocation of heavy elements. Notably corresponding to oxygen, carbon, and nitrogen, is intimately associated with the capabilities of the planetary models, which in turn associate about them. Previously, the analysis of the conception, longevity, and…
Stargirl and Leo have had an impact and everyone in Mica High. In fact I often found myself comparing myself to Leo. Leo is not afraid to be himself. They both have very out going personalities. In this essay I am going to compare myself to Leo to see how we relate, how we are different and how our personalities have changed throughout the book and my life.…
Whenever history is reviewed on Astronomy, great Scientists such as Nicholas Copernicus and Galileo Galilei must be mentioned for their great contribution in the world of Astronomy. Comparing Copernicus with Galileo, we see that Copernicus made great discoveries which Galileo would later use in making his scientific discoveries and proofs. Copernicus is regarded to as the father of Astronomy because of his great contribution towards making the universe understandable to many people. This essay focuses on major accomplishments of Nicholas Copernicus and how Galilei Galileo used them later to become successful scientist explorer.…
Star stuff refers to the knowledge that all the elements in the universe are created from stars, including ourselves. The bigger the star, the heavier the elements.…
If you heat hydrogen to 10 million degrees, it creates energy that stars use to shine. When hydrogen is heated to 10 million degrees, a process called nuclear fusion takes place. It creates a new, heavier element called helium. Some of the matter in this reaction is covered to pure energy which bursts out in all direction. In this process, a new star is created. The first star was a 1000 times bigger than our own sun and it gave off deep blue color. The first elements were created in these stars. If we were to cut open a star, we would see that helium sinks to the center and hydrogen stays near the surface of the star. As Helium reacts with one another, it creates a new, even heavier element called Carbon. The process is very repetitive, causing the star to be layered like an onion. Now, even more elements were created, such as Neon, Oxygen, and Iron. The iron sinks to the center of the star. Iron cannot create another element, therefore the fusion stops. Eventually, the star stops producing the energy and collapses. As the core is compressed, the temperature of the star rises. It eventually explodes and creates what is called a Supernova. The shockwave that comes from the supernova is so powerful, that is forces the iron to form even heavier elements such as gold, platinum, and lead. This eventually leads to more and more elements being formed. It creates everything we see around us. Stars created…
Telescopes are one of the greatest inventions and have led scientists on a fantastic journey of getting closer to understanding the universe. There is no way to research and evaluate outer space without telescopes gathering all of the information that they do. This paper is going to discuss the science of telescopes and explain all of the elements relative to them.…
The needs for an instrument that would take images of the universe from the space were inevitable since there were so many challenges studying space and the universe from earth. The Hubble telescope, named after the great scientist who confirmed the big bang theory, was the solution to this and it has been in space for the more than 20 years it was supposed to live. Over the time, the telescope has sent home so much information that mankind has realized how little they knew about the universe. This paper covers the needs for the Hubble telescope in space, the impacts that it has had in physics and science and what eventually happens to the telescope when its time expires.…
The astronomers taking part in GAMA surveyed cubes of space spanning one million light years per side to observe the fact that the universe is dying. They looked at photos of 21 different wavelengths, from infrared to ultraviolet, in order to measure how much energy each galaxy from each sample was putting out. This research also helped astronomers learn more about how different galaxies form.…
In the universe, there are hundreds of billions of stars. They are formed when gas and dust from space "clump" together. As the mass grows larger, gravity takes over and a core begins to form. The core becomes extremely dense and this compaction causes temperatures within it to rise to the point where nuclear fusion (the burning of hydrogen in a chain reaction) can begin. The heat generated by fusion can reach 24 million degrees F (Fahrenheit). "That amount of heat keeps the outer gas shell expanding while the ultra-dense core keeps from collapsing under its own gravity. The star is said to be in "equilibrium" or on the "main sequence". This is the point where a star spends most of its life." (Aspire.Cosmic-Ray.org, Stars, Main Sequence).…
At first I cried. I was alone. No one could help me – how could they? Just as I was about to give up entirely and close my eyes for the last time, I looked up to the stars. Their bright lights shone down on the lake beside me, dancing upon the water. Stars are truly amazing things. They have the capacity to live for millions of years. These clusters of helium and hydrogen produce magnificent luminescence through nuclear fusion until they reach the end of their lifespan – the Supernova. This explosive death of a star results in the star obtaining the brightness of one hundred million suns, just for a short period of time. And then, the miraculous happens. When a supernova explodes protons and electrons are forced together to combine and produce a neutron star – among the strongest and most dense stars. I was the star, at the end of my lifespan. The crash was the supernova, and the embankment is the nebula – the birthplace of a new star. I had been given a second chance. I would be better, I would be stronger, and I would be…
