Exmoor hosts tenth dark skies festival to highlight UK light pollution

Exmoor National Park in south-west England has hosted its tenth dark skies festival, an event designed to celebrate the area as Europe’s first designated international dark skies reserve. Throughout October, visitors travelled from across the region to participate in the festival, where they were guided by astronomers and ecologists from the national park. The primary goal of the gathering is to allow attendees to witness the clarity of the night sky, which is often obscured by artificial lighting in other parts of the country. By bringing people into the darkness of Exmoor, the organisers aim to highlight the specific effects of light pollution that prevent many residents from seeing celestial objects at home.

Background

The United Kingdom is currently ranked as the 14th most light-polluted country in the world. This statistic underscores the difficulty many people face when attempting to observe the night sky from urban or suburban locations. Exmoor, however, benefits from its status as a protected dark skies reserve, allowing for a much clearer view of the cosmos. The festival serves as an educational platform, featuring activities such as fireside question-and-answer sessions, telescope viewings, and bioluminescence walks through the woods. These events are led by experts who explain the wonders of the universe while simultaneously addressing the environmental implications of excessive artificial light. The park’s designation as an international dark skies reserve is a key factor in its ability to host such events, providing a controlled environment where the natural night sky remains largely unimpeded by the glow of nearby towns like Tiverton.

Why it matters

The festival is not intended to advocate for the complete elimination of artificial lighting, but rather to promote the wise and responsible use of light sources. According to astronomer and teacher Jo Richardson, the focus is on education and encouraging people to think about their environment and how to protect it. Richardson noted that the vastness of space is a powerful motivator for conservation efforts; for instance, she pointed out that Saturn, which is on average 800 million miles away, is visible through a telescope in Exmoor, a feat that is difficult to achieve elsewhere in the UK due to light interference. The experience is described by participants as "mind-blowing," emphasising the emotional and educational impact of seeing the night sky without the veil of light pollution. By demonstrating what is lost due to excessive lighting, the festival aims to foster a greater appreciation for dark sky preservation and encourage behavioural changes in how light is used in daily life.

What happens next

The tenth dark skies festival has concluded its October events, having successfully brought together families and enthusiasts from across south-west England. The ongoing work of the national park and its partners will likely continue to focus on maintaining the integrity of the dark skies reserve. Future initiatives are expected to remain centred on public education, using the park as a living laboratory to demonstrate the benefits of reduced light pollution. The success of the festival in engaging the public with astronomical and ecological topics suggests that similar educational programmes will continue to be a priority for the park authorities in the coming years.
