Recently, art has received a lot of attention in science communication as a tool for engaging a potential audience. However, there are few studies that have analyzed the effects and characteristics of art in science communication. Therefore, the present research is an attempt to examine the emotional and transmission effects of art in the context of science communication. We used two works of art created through collaboration between scientists and artists. These works were then compared with other images of science communication and were analyzed for their communicative effects. Through an experiment that gauged the emotional effect of art, we found that people tend to be impressed by the novelty of a work of art. Through another experiment that probed the transmission effect of art, we also found that a work that used analogy could transmit a complex science concept better than a typical science illustration.
