The Sun

twinkling lights, also known as stars. Stars are one of the most popular astronomical objects and represents the building blocks of galaxies. A star is defined as a vast ball of gas held together by its own gravity. The nearest star to earth is the Sun. Similar to a living organism, stars have a life cycle in which they are born, they develop and grow, and eventually die. Stars begin as a vast cloud interstellar dust (mostly carbon or silicon) and hydrogen gas floating around in space. This…

ability to sustain life? In 1953, Hubertus Strughold proposed the idea of a habitable zone, which is a region outside of the sun that allows for atmospheric pressure and the ability to support liquid water. The distances of the regions from their sun can vary in different solar systems, but are based off of position in the solar system and the amount of radiation given off from the sun. The habitable…

science known today as dynamics and strength of materials. Heliocentric theory. Galileo Galilei made his assumptions based on the heliocentric theory of Copernicus stated that the Earth revolved on itself once a day, and once a year revolved around the sun. Also stated that the earth in its rotary movement, He tilted on its…

planets we can live other than earth? For decades, scientists and astronomers are devoted to these fascinating questions and have done lots of researches. Since the shining stars we can see with our naked eyes on earth are almost fixed stars like our sun, it’s absolutely impossible for life to exist there. Thus in order to search for second earth, the first thing to do is detecting Earth-sized and smaller planets in the habitable zone of stars. NASA’s Kepler Mission aims at this goal using the…

Geometry and Eratosthenes In Professor Russ physical science class, there’s a plethora of subjects you, as a student, are bound to cover. This semester we had discuss over twenty different fields of science; the first being Geometry and Eratosthenes computing circumference of earth. We started the final semester off with two worksheets. The first was the “Angles of a Triangle”, we had to cut out the three angles of the triangle and piece them together in a shape. The three angles form a…

Moon phases affect on tide, tides affect on fishing In order to understand how tides work and how tides affect fishing, the relationship between the motion of the Earth in respect to the Sun and the Moon must first be understood. Newton’s law of gravitation explains that both the proximity and mass of two relative objects increases the attraction present within them. "The Ocean's Tides Explained” article states that on Earth’s axis, the level of the ocean is centered by the centrifugal…

object known to man, the sun, and Jupiter guarded it with cautious patience. Pluto crawled to a wall that lay hidden beneath a towering obelisk, and he watched his brother leave to grab ambrosia from the great hall. Silently walking towards the glowing sphere, Pluto reached his shivering hand to the padlock of the door. His mind raced with the guilt that lingered inside of his ravaged heart, but twisted the key and swung open the magnificent entrance. Pluto then gazed at the sun with awe, and…

on the other hand, is a much more dangerous type of skin cancer, resulting in roughly 10,000 deaths each year. Here’s another frightening fact about melanoma, while BCC and SCC will usually form in an area of the body that has experienced repeated sun exposure, melanoma can be a result from just one really bad sunburn. On top of this, melanoma is also different because it can metastasize and spread throughout the body. So how exactly does ultraviolet radiation cause skin cancer? As I mentioned…

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…

refrigerator. While the sun taunts me with a beautiful spectrum of crisp orange and bright pinks creeping over the horizon, I hurry to leave my grandmother’s beach house and head over to the serene beach. On my way toward the water, dogs are seen in the distance playing in the cool sand and sticking their paws in the salty water. In addition, from laying their eggs in the sand, are long sand trails from horseshoe crabs. Finally reaching the water, I sit down and observe the sun as it slowly…
