Helium

to Earth, which would be a big change if intelligent life would try to live there. The average temperature of the clouds on Jupiter is around negative 224 degrees Fahrenheit. Jupiter’s atmosphere is made up of mostly hydrogen and a small amount of helium (Exploring Life’s Mysteries). Considering the atmosphere and temperature intelligent life would never be able to survive on…

Theory on Lithium in Stars May Be Confirmed The light chemical element lithium is one of the few elements that is predicted to have been created by the Big Bang, 13.8 billion years ago. But understanding the amounts of lithium observed in stars around us today in the Universe has given astronomers headaches. Most heavy elements are produced during supernovae, as massive stars explode in their death throes. However, these events were believed to be too rare to produce the vast amount of…

times bigger than the sun and some can be 250 times smaller. They range in color from red to yellow to blue. Stars are made up of gases and metals. The most important gases needed to make a Star are helium and hydrogen which are two of the lightest elements. Star can shine by burning their hydrogen into helium in their core which is called nucleosynthesis. Then, later in their lives they create smaller amounts of heavier elements like carbon, nitrogen, and oxygen. When they run out of fuel, they…

The star will then start to collapse, but before it is able to completely collapse, a new shell of hydrogen gets going. This causes to outer layer of the star to puff out into a red giant. If a star is large enough, it will be able to begin burning helium to carbon. One this fuel runs out and this new process stops though, the star has absolutely no fuel it is able to use, so it releases its outer layers, which reveals the hot carbon core: the leftover material resulting from this last fusion…

wave, the star is officially born when it reaches an internal temperature of 10 million degrees Kelvin. At this pivotal temperature, the individual hydrogen protons are unable to repel each other any longer, and collide into each other forming a helium atom. This process not only forms a higher element, but also releases energy. It is this energy that we see as sunshine or light, and can feel as heat. By the time it has reached this milestone, the star has been compressed down to only 1…

change and becomes a new element. Nuclear fusion occurs when two elements “combine” and a new element is created. An equation for nuclear fusion would look like, 21H + 31H → 42He + 10n. (Nuclear Chemistry) The two Hydrogen atoms “combine” to become Helium, a new element. Nuclear Fission occurs when an large unstable element splits into smaller elements. An equation would look like, 23592U + 10n → 13956Ba + 9436Kr + 3 10n. (Nuclear Chemistry) The unstable element split into two new elements.…

How do stars form? The stars were born among the dust and scattered throughout the most galaxies. There is an example of dust cloud which is the Orion Nebula.The turbulence in the depths of these clouds produces enough mass of knots.Because its own gravitational attraction,and the gas and dust can begin to collapse. Then the material at the center begin to heat up which is known as protostar . The heart of the collapsing cloud will one day become a star. Since stars are formed from…

hydrogen is unjustified in light of modern design realities and materials. All the above described advantages of solar-electric airships will be even further enhanced by future designs that will safely use hydrogen gas at a fraction of the cost of helium. We now know that the hydrogen gas used was not the cause of the Hindenburg disaster. Bad design and old technology was at fault. Hydrogen is now safely being used in sport balloons in the U.S. and Germany, using modern envelope materials like…

together, and fused with electrons. Neutrons decay in about ten minutes, so within that time there was a set amount of elements created, including hydrogen, helium, and lithium. When astronomers measure the ratios of these elements, they match up with the perspective of the universe once being a ginormous star. 24% of ordinary elements are helium made at that time during the Big Bang. Thanks to the contributions of astronomers, we can understand our universe better than ever before.We still have…

How The Sun Produces Light and Heat Matthew K Paschall Tennessee Tech University Abstract In the center of our solar system sits the key to life on Earth, the sun. The sun provides us with light and heat among other things. The reason for this research paper is to discuss the physics behind the sun and how it creates its light and heat that is so important to our life. How the Sun Produces Heat and Light The sun is the necessary ingredient to many of the processes and phenomena that take…
