Astronomy Cast Ep. 255 - Observing Hydrogen

The beginning of this episode starts off with a very true, and somewhat humorous fact. The narrator of the podcast originally wanted to call the podcast "Hydrogen", but one other person pointed out to him that there is a near infinite amount of hydrogen in the universe, and that would be way too much to cover in one podcast. So, as a result, they decided to name episode 255 to Observing Hydrogen. This episode really just sums up where hydrogen in most prevalent, and what forms it takes. For the first 20 minutes or so, they talk about the interaction of hydrogen within stars. All stars begin as a giant ball of hydrogen that is slowly fused into heavier elements such as helium, and carbon. Further on in the podcast, they state that there are many forms of hydrogen and different isotopes. "Heavy Hydrogen" is also known as deuterium, or H II. In short, it is a hydrogen atom with two neutrons. To sum up the whole idea, hydrogen is literally everywhere and there are so many different forms and configurations that exist in the universe
