Black Rain from

Vimeo.
Black Rain is sourced from images collected by the twin satellite, solar  mission, STEREO.  Here we see the HI (Heliospheric Imager) visual data  as it tracks interplanetary space for solar wind and CME's (coronal mass  ejections) heading towards Earth. Data courtesy of courtesy of the  Heliospheric Imager on the NASA STEREO mission.
Working with STEREO scientists, 
Semiconductor collected all the HI image  data to date,  revealing the journey of the satellites from their  initial orientation, to their current tracing of the Earth’s orbit  around the Sun. Solar wind, CME's, passing planets and comets orbiting  the sun can be seen as background stars and the milky way pass by.
As in Semiconductors previous work 'Brilliant Noise' which looked into  the sun, they work with raw scientific satellite data which has not yet  been cleaned and processed for public consumption. By embracing the  artefacts, calibration and phenomena of the capturing process we are  reminded of the presence of the human observer who endeavors to extend  our perceptions and knowledge through technological innovation.

Semiconductor is artist duo Ruth Jarman and Joe Gerhardt. Through moving image, sound and multi-media installations they explore the material nature of our world and how we experience it, questioning our place in the physical universe. Their unique approach has won them many awards and prestigious fellowships such as the Gulbenkian Galapagos, Smithsonian Artists Research and the NASA Space Sciences. Their work is part of several international public collections and has been exhibited globally including Venice Bienniale, The Royal Academy, Hirshhorn Museum, BBC, ICA and the Exploratorium.
