Halloran began a new body of work is titled Your Body is a Space That Sees in 2015. This work consists of a series of large-scale cyanotypes that present the history and discoveries of a group of women known as “Pickering’s Harem,” or later as the “Harvard Computers.” Working at the Harvard Observatory from the late 1800s through the first half of the 20th century, the members of this group made significant strides in the field of astronomy through the use of photographic glass plates, establishing classification systems for the size, brightness, and chemical content of stars. The contributions of these women were highly impactful, yet they have been largely excluded from the common history of astronomy.
The works in Your Body is a Space That Sees offer the experience of a female-centric catalog of stellar objects in immersive cyan blue and visually illuminate the curiosity and richness of the night sky through depictions of craters, comets, galaxies, and nebula. Halloran's cyanotypes are created through a process of painting and printing, beginning with visual cues from the “Computers’” research. Translations of stellar objects are painted on semi-transparent film then placed on top of paper coated with light-sensitive emulsion—the film and paper are then exposed to direct sunlight. This process results in the production of two related works: a cyanotype print of the positive image in equal scale to its matching painted negative, both created without the use of a camera.
