Spectral Constellations

Spectral Constellations (video documentation excerpt), 2021

variable dimensions / generative animations on LED mosaics
A Semiconductor work by Ruth Jarman and Joe Gerhardt.

Spectral Constellations is a series of generative animations, driven by scientific data of young stars. This data, collected by scientists using a method called Spectroscopy, creates an understanding of structures around distant young stars, where gas and dust come together to form planets. Scientists study the light this matter emits using prisms to split it into its constituent wavelengths, revealing its elemental make-up. By analysing this data over time, spatial formations of the matter can be decoded.

Semiconductor have worked with this spectral data as a physical material, translating it into rings of light which resemble the gradiated discs of planetary and stellar formations. As the data ebbs and flows it introduces a sense of form and motion, waveforms merge and interfere revealing patterns and rhythms, and engage our human tendency towards pattern recognition. The fragmented LED mosaics provide partial windows from which the spectral data shifts and shimmers to create a raw visual experience.

Spectral Constellations was commissioned through a residency with the Planet Disk Connection group and DJCAD at the University of Dundee, Scotland. It has received funding from STFC (Science and Technology Facilities Council), “The planet-disk connection”, (grant number ST/S000399/1) and “Reading between the lines”, grant number (ST/V002058/1).
