Heliocentric uses time-lapse photography and astronomical tracking to plot the sun’s trajectory across a series of landscapes. The entire environment feels to pan past the camera whilst the sun stays in the centre of each frame, enabling us to gauge the earth’s rotation and orbit around the sun. As the Suns light becomes disrupted by passing weather conditions and the environment through which we encounter it, it audibly plays them as if it were a stylus.

It is usually all but impossible to visualize how the earth moves around the sun, even though we know it to be true. Instead we ‘see’ the sun move around us. The ‘heliocentric’ view of the universe was debated from the third century BC onwards and remained contentious into modern times.

Shooting into the sun creates many intriguing artifacts; lens flares and glare spill over the landscape, white outs burn the image, and colours bleed into one, creating aureoles. The power of the sun still exceeds what both the human eye and the artificial eye of the camera can bear. And whilst our knowledge of the universe is ever-growing, we can only encounter and know it from our own humble vantage point.

Black Rain

Black Rain (excerpt), 2009

A Semiconductor work by Ruth Jarman and Joe Gerhardt.

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.

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 Semiconductor’s 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 endeavours to extend our perceptions and knowledge through technological innovation.

Out of the Light

Over time, celestial patterns can reveal themselves through the play of light and shadow on the world around us. Out of the Light is a CGI time based sculpture, which recreates these shadow phenomena to explore how we can make sense of the world through observation; we experience a solar eclipse as observed through the branches of a tree, the rhythm of a city as its shadows phase from days to months to years and the transit of Venus observed through the construction of simple human made tools. Viewing these events with the unaided eye allows for anomalies in the quality and nature of light which are played upon here, to explore our perceptual sensitivities.

Brilliant Noise (excerpt), 2006

SD / HD / single channel + multi-channel versions
A Semiconductor work by Ruth Jarman and Joe Gerhardt.

Brilliant Noise takes us into the data vaults of solar astronomy. After sifting through hundreds of thousands of computer files, made accessible via open access archives, Semiconductor have brought together some of the sun’s finest unseen moments. These images have been kept in their most raw form, revealing the energetic particles and solar wind as a rain of white noise. This grainy black and white quality is routinely cleaned up by NASA, hiding the processes and mechanics in action behind the capturing procedure. Most of the imagery has been collected as single snapshots  by ground based observatories and satellites, they are then reorganised into their spectral groups to create time-lapse sequences. The soundtrack highlights the hidden forces at play upon the solar surface, by directly translating areas of intensity within the image brightness into layers of audio manipulation and radio frequencies.

Thanks to the following solar observatories whose data archives were used in the making of this film: Mount Wilson Observatory UCLA, Lasco/SOHO Naval Research Laboratory, TRACE/LMSAL, Big Bear Solar Observatory/NJIT, SST/Royal Swedish Academy of Sciences, Gong/National Solar Observatory/AURA/NSF Thanks also to: Steven Christie, Iain Hannah, the CSE team and all at the space sciences Lab.

Brilliant Noise was made during an Arts Council England International Artists Fellowship at the NASA Space Sciences Laboratory, UC Berkeley, California, USA.
