The installation is a fusion of solar imagery, sunlight and a specially created sound composition by Duncan Speakman and Sarah Anderson.
Imagery for the artwork has been compiled using 400,000 photographs of the Sun provided by Astrophotographer Dr Stuart Green (taken between May 2018 to June 2024) and NASA observations of the Sun, with guidance from solar scientist, Professor Lucie Green of University College London (UCL).
Helios follows on from Jerram’s previous astronomical artworks, Museum of the Moon, Gaia, and Mars. In Helsinki, Helios forms part of the Helsinki Cathedral Parish’s Let There Be Light! themed month, which explores mental wellbeing and mental health.
