The festival is hosted by Exmoor National Park Authority and has been extended to run for four weeks, after the record success of last years two-week programme. New events added to the programme include Stargazing at Arlington Court National Trust this Saturday at 6.30pm. Tickets for this event and information about planetarium sessions and other events can all be found at exmoor-nationalpark.gov.uk. Airband marketing manager, Simon Britton, said: Exmoors rugged beauty and inky skies are an astronomers delight and the Dark Skies festival brings together everything that national parks represent. Were thrilled to be sponsoring the festival and continuing to strengthen our relationship with the community. In Exmoor, 81sq km of core zone was chosen as the Dark Sky reserve to minimise human habitation but to maximise open land access and points of interest.
