APOD 2.3

             The creation of stars must be a complex manifestation of matter and events that come together after years of build up. After reading the description and then looking at the picture, I really dont understand whats going on in the image. It appears to just be a nebula. I cant find any distictive central point, where gravity brings the star together. Also even when these gases come together, why are they hot and how do they sustan their own heat drifting through space. Space is cold, relative to our temperatures in Florida. So shouldnt drifiting gases lose their heat energy without any central energy source keeping it. Like stars hold their energy longer because of their dense core.
