Aesthetics and Astronomy: Studying the Public’s Perception and Understanding of Imagery From Space

This study examined the scientific understanding of astronomical pictures by experts and nonexperts. It explored how both groups perceive astronomical images and their understanding of both what they are seeing and the science that underlies the images. Data comprised n = 8,866 responses from a survey linked to the NASA Astronomical Picture of the Day website and four focus groups held at the Harvard—Smithsonian Center for Astrophysics. Results indicated that variations in presentation of color, explanation, and scale affect comprehension of astronomical imagery. With those who are more expert, shorter, more technical explanations are effective; however, scales are still necessary for complete comprehension. Experts tend to look at the images from a more scientific, data-oriented perspective while nonexperts are more likely to focus, especially initially, on the aesthetic or emotional values of the images. Results provide suggestions for educational outreach to the public.

Creating Public Science With the From Earth to the Universe Project

The authors propose formalizing an entity for the sciences and science communication that is akin to public art in the humanities: public science. Public science might be able to play a role in enhancing and supporting society’s relationship with science by embedding science content into everyday experiences. The authors examine one project and its potential impact in public science. From Earth to the Universe has placed astronomy images in “nontraditional” science communication venues such as parks and airports. From Earth to the Universe could serve as a model for a type of public science, an attempt to make science accessible to nonexperts in public spaces.

Examining perceptions of astronomy images across mobile platforms

Modern society has led many people to become consumers of data unlike previous generations. How this shift in the way information is communicated and received - including in areas of science - and affects perception and comprehension is still an open question. This study examined one aspect of this digital age: perceptions of astronomical images and their labels, on mobile platforms. Participants were n = 2183 respondents to an online survey, and two focus groups (n = 12 astrophysicists; n = 11 lay public). Online participants were randomly assigned to 1 of 12 images, and compared two label formats. Focus groups compared mobile devices and label formats. Results indicated that the size and quality of the images on the mobile devices affected label comprehension and engagement. The question label format was significantly preferred to the fun fact. Results are discussed in terms of effective science communication using technology.

Capturing the many faces of an exploded star: communicating complex and evolving astronomical data

This study explored how different presentations of an object in deep space affect understanding, engagement, and aesthetic appreciation. A total of n = 2,502 respondents to an online survey were randomly assigned to one of 11 versions of Cassiopeia A, comprising 6 images and 5 videos ranging from 3 s to approximately 1 min. Participants responded to intial items regarding what the image looked like, the aesthetic appeal of the image, perceptions of understanding, and how much the participant wanted to learn more. After the image was identified, participants indicated the extent to which the label increased understanding and how well the image represented the object. A final item asked for questions about the image for an atronomer. Results suggest that alternative types of images can and should be used, provided they are accompanied by explanations. Qualitative data indicated that explanations should include information about colors used, size, scale, and location of the object. The results are discussed in terms of science communication to the public in the face of increasing use of technology. Abstract
