1896 eclipse in Norway

From the NNHS historic collections

Solar Eclipse

Since its founding in 1876, the Northamptonshire Natural History Society has shared in one of astronomy’s most captivating pursuits: the observation of solar eclipses.

In an age before affordable travel and digital imaging, witnessing a total eclipse required determination and careful planning. In 1896, members of the Society undertook a remarkable journey to Norway to observe a total solar eclipse – travelling hundreds of miles in the hope of standing, briefly, in the Moon’s shadow. Expeditions like this reflected the spirit of curiosity and dedication that has long defined the NNHS.

That same spirit continues today. On 12 August 2026, a spectacular total solar eclipse swept across parts of Spain, Iceland and Greenland, while the UK experienced its deepest partial solar eclipse for decades. Across much of Britain, more than 94% of the Sun was covered as the eclipse reached its maximum close to sunset, creating one of the most dramatic astronomical sights visible from the UK in a generation. Many NNHS members travelled to the path of totality, while others gathered across Northamptonshire to witness this remarkable event.

While technology has transformed how we observe and record these events, the sense of wonder remains unchanged. From Victorian expeditions to modern-day observations, solar eclipses connect generations of naturalists and astronomers. They remind us that, however much the world changes, there are still moments when we all look up together in awe.

Astral Projection

Among the photographs taken during the NNHS expedition to Norway for the 1896 solar eclipse is a striking image of the Sun at totality, its disk completely obscured and surrounded by the delicate streamers of the solar corona. To late nineteenth-century observers, such images could appear almost otherworldly.

The radiating structures of the corona – captured imperfectly by early photographic methods – were sometimes described in terms that reflected the wider intellectual interests of the time, including ideas about unseen energies or even “astral” emanations.

Today, these features are understood as part of the Sun’s outer atmosphere, shaped by complex magnetic fields and visible only during total eclipse. Yet the photograph remains a powerful historical record: not only of a scientific observation, but of a moment when the boundaries between careful study and imaginative interpretation were still being explored. In this way, it reflects both the curiosity of the 1896 expedition and the enduring sense of wonder that continues to inspire NNHS members today.

Our experienced amateur astronomers bring a wealth of knowledge and practical observing experience, from the Solar System to distant galaxies, nebulae, star clusters and variable stars. Knowledge is freely shared, whether you want advice on observing and equipment, want to develop your existing skills, or are simply fascinated by what lies beyond our planet.

You don’t need to own a telescope or be an expert to join us. All levels of knowledge are welcome – from complete beginners to experienced observers.

Come along, ask questions, share what you know and discover more about the universe with us.

Clouds at Night

Noctilucent clouds, often called “night-shining clouds,” are one of the most magical sights you can catch in the sky. Unlike ordinary clouds, they form incredibly high above Earth—so high that even after the Sun has set for us, they can still be lit up from below the horizon. This gives them a glowing, electric blue or silvery appearance that almost looks unreal. They’re most often seen during summer evenings near the horizon, especially in northern regions. If you ever spot thin, shimmering clouds lighting up the twilight sky, you might be looking at one of the rarest and most beautiful cloud types on Earth.
