The Universe is not permanent 1. All the stars in the galaxies in the Universe generate light and heat energy through nuclear fusion. 2. The stars shine by burning hydrogen. When the source of hydrogen in the Universe is exhausted, all the stars will burn out and die.
Electromagnetic Radiation: Radiation consisting of oscillating electric and magnetic fields, namely gamma rays, X-rays, visible light, ultraviolet and infrared radiation and radio waves. Interstellar Medium: Interstellar gas and dust. Julian date: A Julian date or day number is the number of elapsed days since the beginning of a cycle of 7,980 years invented by Joseph Scaliger in 1583. Magnetic Field: A region of space near a magnetized body within which magnetic forces can be detected. Neutron Star: A very compact, dense stellar remnant composed almost entirely of neutrons.
Comet tails are made up of simple ionized molecules, including carbon monoxide and dioxide. By action of solar wind, molecules are blown away, forming a thin stream of hot gases continuously ejected from the solar corona. In case you do not know the meaning of a solar corona, it is the outermost atmosphere of the Sun. Amazingly, the thin streams of high gases move at a speed of approximately 400 kilometers (250 miles) per second (as cited in Yeomans 1991 p. 185). In addition, a comet frequently also displays smaller, curved tails composed of fine dust particles blown from the coma by the pressure of solar
How did Hubble discover it? Hubble's LAW says that the universe is expanding and the further galaxies are traveling faster away then the closer galaxies. How does the abundance of light elements provide support for the big bang picture of the universe? It shows the first elements of our universe hydrogen helium and lithium was formed 3 minutes after the bis bang. Is the universe getting warmer or colder?
There may be a small core of rock and perhaps ice at the center. This is surrounded by an ocean of liquid hydrogen and helium in the form of a metal. Above this is a layer of liquid hydrogen and helium, and above this a thick atmosphere. Jupiter is radiating energy, possibly as a result of radioactivity. The most famous feature is the Great Red Spot, which may be a huge storm in the atmosphere.
The idea could be considered as madness but others may say THIS IS PHYICS! ￼ After the giant nebula has started to converge it forms a Protostar, this Protostar is halfway between a nebula and a star. Eventually it gets to a point where it cant contract any more gas and the tremendous pressure starts to cause tremendous hear, and thus nuclear fusion begins, true story. ￼
The process of changing one element into another is called transmutation. The two main ways that a transuranic nucleus can be produced is by bombarding its nucleus with ions or neutrons. These ions or neutrons can be captured by the target nucleus and produce heavier nucleus. Transuranic element 1: U-238 is bombarded with neutrons it can be converted to U-239 which then undergoes beta decay to produce neptunium and plutonium. Pu-239 is changed to americium-241 by neutron
Science of Stars Paper SCI/151 December 14, 2011 Science of Stars Paper Stars are the most recognized astronomical objects all over the universe. They represent the most fundamental building blocks of the galaxies. The histories of the stars in the galaxies are traced through the distribution, compensation and the age and dynamics and evolution of that galaxy. However, the stars are responsible for the manufacture and distribution of heavy elements such as carbon, nitrogen, and oxygen, and their characteristics are intimately tied to the characteristics of the planetary systems that may coalesce about them. Consequently, the study of the birth, life, and death of stars is central to the field of astronomy. ]
The element used in atomic bombs is Uranium-235. Uranium's atoms are unusually large, and henceforth, it is hard for them to hold together firmly. This makes Uranium-235 an exceptional candidate for nuclear fission. Uranium is a heavy metal and has many more neutrons than protons. This does not enhance their capacity to split, but it does have an important bearing on their capacity to facilitate an explosion.
