If you have been doing much reading on astronomy‚ you have probably come across the term "red shift". When astronomers are explaining how far away a distant object is‚ they will usually say something like "The red shift of the galaxy (or other object) indicates that it is about 4 billion light years away". What does "red shift" mean‚ and how can it tell us how far away an object is? Since most of the things we look at in the sky are so far away‚ we cannot visit them and find out what they are made

There are a large number of types of nebula‚ each vastly different from one to another. These types of nebula all have their own speciality in regard to the way they were formed and how they fit their purpose as nebula. The names of these types of nebula are; H-II regions‚ planetary nebula‚ supernova remnants and diffuse nebula. An H-II region is a region of partially ionised gas. What also distinguishes H-II region from the others is that it contains vast amounts of ionised hydrogen‚ meaning it

While quite a bit of Fontenelle sounds matter-of-certainty to us as his discussion of limitless universe‚ his hypothesis on life beyond the Milky way Galaxy and his examination of space travel; we need to recall that distributed his book three centuries back was dangerous business. The thoughts he was bandying about were intense‚ disputable‚ even prohibited. As they had been hardly known to the normal per user before he clarified and scattered them‚ these surprising thoughts abruptly turned into

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
