Formation of interstellar molecules

William D. Watson wrote a research paper on how interstellar hydrogen molecules reacted to form many of the stars in the universe. He was a physicist who graduated from MIT and worked in theoretical astrophysics. He was led to do research on this topic because he wanted to know if hydrogen ions could react with other hydrogen molecules to create small interstellar molecules. He found that these reactions do indeed make up a good portion of interstellar gases and this was important in helping us understand the make up of the universe. This information could be important to many people who are interested in astronomy because it is an interesting topic that answers some of our questions about what is actually out there.
