Milky Way Galaxy is of particular interest to the planet Earth, and the people that reside there, because the planet is one of, possibly, billions contained within it. The term galaxy is used when a large group of stars, generally a billion or more, have clustered together due to a similar attraction to some gravitational attraction. The Milky Way Galaxy is actually a conglomeration of others such as the Canis Major Dwarf Galaxy and the Sagittarius Dwarf Galaxy whose masses have been consumed by the Milky Way (Wethington, 2009). This collection of "solar masses" (Wethington, 2009) is joined by an even larger group of planets (much like the solar system in which the Earth is a resident), dust clouds, gas, comets/meteors and other debris. The Galaxy got its name from the fact that people in more ancient history than ours could see the impression of a milky, or cloud-like line in the night sky. The people...
This impression was changed in the 1600's when Galileo aimed his fledgling telescope at the night sky and determined that the assumed gas cloud was actually a large number of stars (he thought they only numbered in the thousands) just beyond normal visual sight. It was later determine, of course, that this was actually the edge of the Milky Way Galaxy.
Science teachers can utilize this article by updating their curriculum related to the universe. While textbooks currently being used convey the traditional notions of the past, newer developments need to be incorporated immediately. Most current aspects of science seem to change rapidly. Astronomers such as Fabio Governato from the University of Washington have demonstrated how supercomputers can be used to replicate the activities in space, which are invisible to our
Montessori -- Cosmic Educational Strategies The success that the Montessori system of learning has achieved is in part due to the theory of cosmic education and its affect on children. Maria Montessori wrote that the universe is "…an imposing reality, and an answer to all questions… All things are part of the universe and are connected with each other to form one whole unity…" (To Educate the Human Potential). Moreover, this
The singularity at the beginning of the Big Bang did not begin in space; it was the origin of space. Black Holes While singularities are difficult to define and to prove, black holes are not. Black holes are areas with such extreme gravitational pull that the velocity an object would need to escape them is greater than the speed of light, and, thus, unattainable. Bl.ack holes are observable and have been
