Avenue of Stars Rings - from interstellar molecular cloud to the birth of stars

When we looked up the night sky (if lucky), you might see is a little bit of visible stars. Set up a telescope, deep look into the distance outside the galaxy, is visible Stars. Stars, can be said to be the universe's basic "particle." Where did they come from? What is the process of heat and light so that they eventually boarded the "Avenue of Stars"? The current understanding of stellar astronomers is diffuse in interstellar molecular clouds bred birth. A cloud due to the shelter, it is difficult to directly use the naked eye, or visible light observations to study the star formation process. Today, let us together with astronomers through the millimeter wave, sub-millimeter wave, and infrared band observation, spy buried in a cloud, the star of a variety of interesting phenomenon was born.
