Summery Analysis The Milky Way is the earths’ galaxy and it’s happening’s hold the interest of many scientists. In Daryl Haggard and Geofrey C Bower’s article “Into the Heart of the Milky Way” they discuss a phenomena that was discovered in the nucleus of the Milky Way only forty years ago which is a supermassive black hole called Sagittarius A* right in the core. Throughout the article the author’s explain many unpredictable events that have been observed. The article begins by explaining the G2

The Stellar Lives of Stars Stars are giant nuclear reactors. In the center of stars‚ atoms are taken apart by tremendous atomic collisions altering the atomic structure and releasing an enormous amount of energy that makes stars hot and bright. Nuclear fusion is an atomic reaction that fuels stars. In fusion‚ many nuclei combine together to make a larger but different element‚ and the result of this process is the release of a lot of energy. Stars are powered by nuclear fusion in their cores

Carolyn Godfrey English 101 Ms. Lazzo 10/26/2010 Theories of how Life on Earth began We certainly know that our universe exists‚ however‚ this knowledge alone has not satisfied mankind’s quest for further understanding. Our curiosity has led us to question our place in this universe and furthermore‚ the place of the universe itself. Throughout time we have asked ourselves questions such as: How did our universe began? How old is our universe? How did matter come to exist? Obviously‚ the search for

What are the properties of a black hole? How do they form? Why are they invisible? “A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—including particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.” (Source 1) The collapsing or dying of a star causes the strength of gravity to be so strong that light can’t

black hole. Stellar-mass black holes are born when very massive star run out of nuclear fuel. The star will explode in a supernova and the remains will be a black hole. Scientists know less about supermassive black holes‚ which live in the centers of galaxies. 5. How do black holes differ from each other? In other words‚ what types of black holes are there? Black holes differ from each other in three characteristic properties: their mass‚ their spin‚ and their electric charge. Aside from there three

BLACK HOLE Introduction: "A luminous star‚ of the same density as the Earth‚ and whose diameter should be two hundred and fifty times larger than that of the Sun‚ would not‚ in consequence of its attraction‚ allow any of its rays to arrive at us; it is therefore possible that the largest luminous bodies in the universe may‚ through this cause‚ be invisible." -- Pierre Laplace‚ The System of the World‚ Book 5‚ Chapter VI (1798). Evolution of Stars 1. Clouds of Hydrogen begin condensing

The Origin of the Solar System A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. The disturbance could be‚ for example‚ the shock wave from a nearby supernova. As the cloud collapses‚ it heats up and compresses in the center. It heats enough for the dust to vaporize. The initial collapse is supposed to take less than 100‚000 years. The center compresses enough to become a protostar and the rest of the gas orbits/flows around it
