Think About This!
Professor McMahon and his students aren't the only people who study molecules that can be found in space. In fact, many researchers work on similar projects. For this reason, many researchers collaborate (work together) with other researchers. These researchers could be at the same university, at a different university, or they could work for a government agency or a business.
Additionally, some research projects involve work in many different research areas. In this case it is necessary that researchers work together to solve a problem. For instance the McMahon group can make their molecules and study them, and then compare their results to those of the radio astronomers! In order to further their understanding of the research area, and to get a new perspective on their project, researchers often work with other people!
