The source I chose to evaluate is an article called “Is Pluto a planet?” written by Graham Rax. This source was published by Kalmbach Publishing Company in 1999, and mainly talked about is the Pluto should be consider as a planet or not. For this paragraph, it mainly talks about what is planet, what the figure does the Pluto has, and it give a conclusion that we can’t define the Pluto as a planet or treat is as a member of Kuiper Belt. We can tell that the article was published by a formal…

People may suggest that everyday energy used is from power plants, which stores energy to power a whole city. It is usually thought of renewable resources, such as water, the sun, wind, etc., to be nothing but ordinary resources. Without individuals really thinking about it, they can use the everyday resources to power energy through many types of technologies used today. People have created machinery that can use the renewable resources for energy. There may be disadvantages, but current energy…

A spiral galaxy is a certain kind of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, forms part of the Hubble sequence. Spiral galaxies consist of a flat, rotating disc containing stars, gas and dust, and a central concentration of stars known as the bulge.(Sloan) Spiral galaxies resemble spiraling pinwheels, nearly 77% of space consists of spiral galaxies. Though the stars and other visible material contained in such a galaxy lie mostly on a…

Summary Assignment #1 Sunspot Cycle: A Brief History In 1610, shortly after viewing the sun for the first time through a telescope, Galileo became the first European to observe sunspots, which are visibly darker, cooler areas on the sun. A little over 200 years later (in 1843), amateur German astronomer Samuel Heinrich Schwabe discovered that there is a cyclical, eleven, and by extension to a full cycle, twenty-two year pattern to the variation of sunspot counts known as the sunspot cycle. In…

3. Tasks In order to get answers to the Mission questions, Euclid will measure the geometry , expansion rate and structure growth in the Universe as a function of redshift. This map, spanning 3/4 of the lifetime of the Universe will complement the single snapshot at z ≈1100 made by WMAP and Planck. By combining the use of Redshift measurements (4.1), Weak gravitational lensing (4.2) and Baryonic Acoustic Oscillations (4.3), both Dark Energy (DE) and Dark Matter(DM) will be investigated in the…

“The Sun is alone too but it still shines” by an anonymous author. This quote shows us that just because you are alone doesn't mean you can stop being yourself. In “All Summer In A Day”, by Ray Bradbury, the main character Margot discovers how hard it is to fit in. As Margot tries to fit in and explain the sun to her new classmates, she finds herself alone because none of the kids believe her stories about the sun. Some students then find out that she may be returning to Earth, away from the…

He used his learning to find out what way comets were facing and he found out the moon has gravity which controls the tide and the exact time the time changes. That proved the sun was in the middle of our solar system this is also known as "heliocentric model." Him finding out gravity came to him over time. All of this information backs up the facts of our next topic Earth. Isaac Newton predicted that Earth is probably a sphere flush at magnetic poles. which…

centuries, however, humankind still lacks an answer. Human beings are cognizant and curious of the world surrounding them. So much so that governments, including the United States government, spend billions of dollars on space programs to explore the solar system, the planet Mars in particular. As our earth develops into a planetary, polluted waste, Mars could eventually become our new home. Scientists believe Mars sustained or could sustain life, yet, they still can't uncover what lies…

Vistas’ path around the sun. Because of this dawn was able to catch up to Vesta and very slowly get pulled into Vestas’ gravitational pull. This was the first-time ion engines were used to send a spacecraft to orbit around a distant object in our solar system. Folger lets us know that in the beginning NASA canceled the Dawn mission because of how expensive it would be to support the mission and additionally they were concerned with the technical problems that could occur to the novel propulsion…

Stars have been mystery for quite a while in history, but Bethe's work made certain conclusions about the nuclear reactions that are possible in star, and how much energy comes from these reactions. The main goal is to measure which reactions are favored to accurately predict how stars emit energy. Also it must be proven that heavy elements are not likely to be formed by calculating probabilities of Nuclear reaction based on favored energy. The most favorable reactions in stars include the…
