Helium

Without carbon, our universe would be made of only hydrogen and helium and the absent items would range from rocks to trees to humans. Carbon is an important building block of the elements and is essential to almost all life. Not only is the element carbon important in its solid form, but carbon dioxide is a gas that…

When hydrogen is used up, helium begins to fuse to carbon and the larger element such as calcium and magnesium. Once the main hydrogen supply is used up the outer layers of the star begins to collapse inward toward the core. This process generates heat which temporarily counteracts…

to it as a massive nuclear reactor that burns numerous amounts of hydrogen; and just like an actual nuclear reactor, hydrogen is the essential fuel in nuclear fusion reactions. The hydrogen in these fusion reactions fuse together to form beryllium, helium, and lithium atoms. “The temperature on the surface of the Sun is approximately six thousand degrees Celsius. While at its core, it is about a million degrees Celsius” (Solarsystem.nasa.gov,2013). The Sun, just like all other stars in the…

Neptune is the most dense, even though it is the smallest out of the gas giants. Neptune was named after the Roman god of sea because it looked like a giant ocean, due to its blue appearance. Neptune is composed of many gases such as hydrogen (80%), helium (19%), and methane (1.5%). It is also overall composed of 25% rock and 60-70% ice. Neptune is 3.9 times bigger than earth. The mass of Neptune is 1.02 x 1026 kg, or 17.15 times as much as the mass of earth. The radius is 15,299 miles.…

Dr. Hinderberg Dr. Eckeners dream of a regularly scheduled Zeppelin airship service across the North Atlantic to America was finally realized with the construction of the Hindenburg. It was designed to carry 50 passengers in a luxury and comfort never before seen in Airship Travel. It was to be one of Nazi Germany's finest airships. The Hindenburg was supposed to represent the greatness of Germany and its leader, Adolf Hitler. Because of this the Hindenburg was emblazoned with large swastikas on…

The paradox Olbers Heinrich Wilhelm Olbers German astronomer by 1826 in formulated physical paradox that was previouslyJohannes Kepler (1610 in), and Halley and Cheseaux (the 18th century described) as well. The paradox is that if the universe is infinite, we'd have an infinite number of stars light of the result The combination of the sky at night it should be clear to all.However, experience to the contrary. [1] Assumptions [edit | edit source text] If 1. the universe is infinite, 2. an…

V. The Cat’s Eye Nebula One of the most famous nebulae is the Cat’s Eye Nebula (NGC-6543); it was discovered by William Herschel in 1786. NGC-6543 is located in the northern constellation of Draco; it appears as a blooming center with surrounding and expanding rings. The NGC-6543 has a historical importance because it was the first nebula to be studied spectroscopically by the astronomer William Huggins in 1864; this study revealed the distinctions between PNe and the other gaseous nebulae.…

magnetic field strength and velocity. By using a Daedalon (e/m) Apparatus paired with Helmholtz coils and a glass bulb filled with helium gas, students were able to observe electrons travelling in a circular path. This is due to the uniform magnetic field produced by the coils which is perpendicular to the velocity of the electrons, the force acting on the electrons, and the helium gas that allowed students to see the electron beam travelling in a circular path. Anyways, students…

Originating from cosmic events such as supernovas, chemical elements are the foundation of all life. Billions of years ago, a violent explosion known as the Big Bang produced helium, hydrogen, and all of the matter and energy in the universe. Generated in the cores of stars, nuclei combined to form atoms which constitute the basic unit of all chemical elements. The extensive expansion of the universe induced the birth and demise of more stars and consequently the creation of more elements.…

it provides us light, heat, and more. It can reach surface temperatures of about 5,276 degrees Celsius, and 10,340 degrees Fahrenheit. The composition of the Sun changes slowly as hydrogen is converted into helium in its core; however, it is currently made up of around 70% hydrogen, 28% helium, and less than 2% of other metals. From satellite images of the sun in space, it appears to be a great, red, fiery ball of energy. The reason why it appears to be so bright is because its intense power and…
