Prominences 1. Prominences are immense clouds of glowing gases that erupt from the upper chromosphere. 2. The loops or arches of gases may shoot as high as 100 000 kilometres from the surface of the Sun. This allows some of the surface gases, mainly hydrogen and helium, to escape into space.
The Milky Way galaxy is the galaxy in which our solar system lies. It consists of four major arms and the sun is located in the Orion arm. 3. The Big Bang is the birth of the expansion of the universe and it is about 14 billion years old. 4.
How does cosmology differ from astronomy? Cosmetology studies the birth and the possible deaths of the universe where as astronomy studies the actual objects in the universe What is a galaxy? How are galaxies distributed in the universe? A galaxy is a collection of billions of stars and gasses being held together by gravity. Name the different types of galaxies and their distinguishing characteristics.
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.
This causes the comet to brighten enormously. Sometimes this develops a brilliant tail, extending millions of kilometers into space. Even as the comet recedes again, the tail is directed away from the sun. What are these spectacular comet tails composed of? Comet tails are made up of simple ionized molecules, including carbon monoxide and dioxide.
Depending on the current temperature on the stove the only way that you would be able to make the stove burn hotter would be to raise the amount of voltage. This means that the voltage would have to be multiplied to make the stove have a larger resistance thus making the heat higher. 7. The Hubble Space Telescope can see stars and galaxies where brightness is 1/50 of the faintest objects now observable using ground-based telescopes. Use the fact that the brightness of a point source, such as a star, varies inversely as the square of its distance from an observer to show that the space telescope can see about seven times farther than a ground-based telescope.
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. 
Then Kaku states that force fields can do more than deflecting laser beams because it can levitate objects by the use of magnetic force fields. To support that, he explains that when we place two magnets opposite to each other, the two magnets will repel each other. However he wrote that making force fields and to levitate heavy objects is nearly impossible since we lack advanced technology. For my response, Kaku doesn’t completely explain everything. Suppose that you have a structure on a planet or a spaceship in the middle of nowhere, and suppose you don't want the force field on all the time either because there are times when protection isn't needed.
Firstly, approximately 15 million years ago, a tremendous explosion known as the ‘Big Bang’ started the expansion of the universe. At this point, all the matter and energy in the universe was contained in one point. However, it was not a conventional explosion. Rather, it was an event filling all of space with the particles of the embryonic universe rushing away from each other. In the miniscule fractions of a second after the Big Bang, the universe was tremendously hot, and as a result, both matter and antimatter was rushing apart in all directions.
Consequently, the study of the birth, life, and death of stars is central to the field of astronomy. ] (Netting, 2011) We explore the complexity of the stars and what astronomers use to determine fundamentals of their temprature, speed , rotation, and composition.
